one of my webpages uses the following sql query to allow the user to search through the database and present the qualifying data in gridview:
SELECT * FROM [Table1] WHERE ([comments] LIKE '%' + ? + '%')
how could i expand this so that the user can also search through the database but instead by searching through another column such as [type]?
thanks in advance
Hi all,
I have a gridview bound with a SQLDataSource. I am using the Update feature of the SQLDataSource to update a SQL Server database with values entered into the gridview. However I am not getting it to work. I believe this is due to the controls that contain the user entries are not the gridview itself, but rather child controls within the gridview. I have been using the names of the actual controls but nothing happens. Upon submit, the screen returns blank, and the database is not updated. Here is some code:
<asp:GridView ID="GridEditSettlement" runat="server" AutoGenerateColumns="False" BackColor="Navy"
BorderColor="IndianRed" BorderStyle="Solid" Font-Names="Verdana" Font-Size="X-Small" DataSourceID="SqlDataSource_grid" AllowPaging="True" AllowSorting="True" ForeColor="White" DataKeyNames="legid">

</UpdateParameters>
</asp:SqlDataSource>
As seen above, controls such as txtPrimarySettlement are referenced but the update is not successful. The text boxes are within the GridEditSettlement gridview. In the .aspx code I cannot use FindControl (at least I don't think it will work).
So the questions are: Is it possible to reference the child controls, if so - how? Is there another way to do this, such as in the vb code behind - in the either the gridview's RowUpdating event or the SQLDataSource's Updating event.
What is the best approach? Anyone come up against this issue before?
Thanks,

Hi, I am porting a massive VB6 project to ASP.net 2005. Most of the code is fine, however because the original developers used lots of data controls and my own time restrictions I thought to replicate the functionality by using Sqldatasource controls instead.
These data controls are bound to DBtruegrids. The project has has lots of code like...
AdodcOrders.Recordset.RecordCount > 0 or If AdodcOrders.Recordset.EOF or AdodcOrders.Recordset.MoveNext() or
AdodcDetail.Recordset!FieldName
The problem is the sqldatasource control doesn't have a recordset/dataset property which I can access and manipulate, or does it? What should I do to get round these? The project has thousands of lines like this in so its not feasible to rewrite it (although if I could I would!).
Any suggestions please gratefully appreciated.
many thanks

NET 2.0
I am using Visual Studio Express 2005 for database web developement.
I have created a database with 5 tables. Two are associative tables.
They are
SoftwarePK SoftwareID Title
SoftwareSolutionFK SoftwareIDFK SolutionID
SolutionPK SolutionID Title
CategorySolutionFK CategoryFK Solution
Category
PK Category Title
Criteria for a search with three sources of input into a SqlDataSource attached to a FormView for paged out.
The following are the Search Criteria input sources:1) ListBox in Multiple Selection Mode2) CheckBoxList with Mutiple checks posible2) TextBox with key word search in Title.
Each Solution has 0 or many Categories and 0 or many Software.
When the records are entered in the database, the associative information for Categories and Software are populated to filter thereturned values.
In NET 1.1, I would create a search string like the following in code behind by looping through the CheckBoxList and ListBox finally adding the TextBox:
SELECT Solution.SolutionID, Solution.Title FROM SolutionWHERE Solution.SolutionID IN ('2','3','5') AND Solution.Title LIKE '%Math%'
I am unable to update the SelectCommand in the ASPX page.
However, when I use the I have used theSystem.Web.UI.WebControls.SqlDataSources"SelectQuery Builder"I receive the following in the Source for ASPX: <asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT Solution.SolutionID, Solution.Title
FROM
Solution INNER JOIN CategorySolution ON Solution.SolutionID = CategorySolution.SolutionID
INNER JOIN SoftwareSolution ON Solution.SolutionID = SoftwareSolution.SolutionID">
<SelectParameters>
<asp:ControlParameter ControlID="CheckBoxList1" DefaultValue="%" Name="CategoryID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="ListBox1" DefaultValue="%" Name="SoftwareID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="txtTitleSearch" DefaultValue="%" Name="Title" PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource> I receive duplicate records and not sure if the code generated accesses the Mutiple Selected values in the CheckBoxList1 and ListBox1.Question: 1) If the SelectQuery generator will not access multiple selected values from the CheckBoxList1, how can I use code behind to replaceSelectCommand in the ASPX page?2) What is the best solution for using the CheckBoxList1, ListBox1, and TextBox for filtering my results? Sample code, references to solutions, corrections on logic, a new approach, how to use the wizard correctly would all be greatly appreciated.3) Can Multiple Selection Controls be use with a SqlDataSource SELECT Command?Thanks for your time,Sincerely,Unhistoric
Thanks for your help.
I'm just getting into ASP.NET 2.0 and started using the SqlDataSource control to declaritively connect to a database. I was wondering if I have two SqlDataSource controls on one page with two select commands querying the same database, will the that create to seperate instances of opening and closing the connection to the database, or will it open the database once, execute both queries, and then close the connection. It seems that if it creates two separate connections, it would still be more efficient to to connect to the database programmatically using ADO.NET. You would only need to make one trip to the database, pull down all of your data, and then close the connection.

Hi,
I have a master/detail scenario whereby to populate a formview, the user selects a row in the gridview. The SqlDataSource used to populate the formview needs to check 2 columns from the gridview, ZRef (which is the SelectedValue of the Gridview) and ZName (a string).
From searching the forums it looks like I have to programmatically assign the SelectParameters in order to get ZName from the gridview. Seems fair enough, so I set the parameters in the 'Selecting' event of the SqlDataSource. (Code shown below).
However the formview never shows. In debug I can see that the values I'm setting in the SelectParameters.Add are correct; and if I set the default values for those parameters in the SqlDataSource itself, everything works fine.
Can anyone point me to some sample VB code that does this - I'm sure this must be a common situation.
Thanks.
Protected Sub sdsOff_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs)
Dim tmpSDS As SqlDataSource
Dim tmpLBL As Label
tmpSDS = CType(FormView1.FindControl("sdsOff"), SqlDataSource)
If tmpSDS Is Nothing Then
Server.Transfer("ErrorOnPage.htm")
End If
tmpLBL = Me.GridView1.Rows(GridView1.SelectedIndex).FindControl("lblName")
If tmpLBL Is Nothing Then
Server.Transfer("ErrorOnPage.htm")
End If
tmpSDS.SelectParameters.Clear()
tmpSDS.SelectParameters.Add("ZRef", GridView1.SelectedValue) 'In debug, this shows 7 - which is correct
tmpSDS.SelectParameters.Add("ZName", tmpLBL.Text) 'In debug, this shows 'Fred Bloggs' - which is correct
End Sub
Hi ... hope you can help.
I would like to use the Data Mining Web Controls which ship with the MSSQL2005 Beta 2. The installer (BetaAnalysisServicesSamples.MSI) is supposed to create a new virtual directory and should also create the DataMiningHTMLViewers.dll according to "ReadMe_Data_Mining_Web_Controls.rtf"
But the MSI only creates a few new directories with the source code and a deployment project (DMHTMLViewersSetup.vdproj) which won't open with VS2003. The solution apears to be for VS2005.
How do I install the Web Controls?
i'd like to add the data mining viewer controls into visual c# 's toolkit....is it possible...
is there a way how i could create forms and import the minned pattern into these forms using the data mining viewer controls??
Hello,
I have SQL 2005 and Visual Studio 2005 and I´m trying to install the Data Mining Web Controls. I downloaded the SQL Samples and I´m following the instructions of the "ReadMe_Data_Mining_Web_Controls.htm" file, but when I try to install de data mining web controls the setup.exe does´nt create the folder "C:Program FilesMicrosoft.AnalysisServices.DataMiningHtmlViewers " and the folder "C:Inetpubwwwrootaspnet_clientmicrosoft_analysisservices_datamininghtmlviewers ".
Then, I don´t have the file "C:Program FilesMicrosoft.AnalysisServices.DataMiningHtmlViewersMicrosoft.AnalysisServices.DataMiningHTMLViewers.dll " for using the web controls.
Can somebody help me?

My problem is about using Data mining web controls in asp.net 2005. My SQL Server 2005 is not SP2. My problem is whenever i want to use desicion tree viewer in aspx page it gives me an error : "Error: Error (Data mining): The specified DMX column was not found in the context at line 1, column 69". I have populated database,model,tree,server properties in design time and connection property ( An oledb connection) by code-behind with that connection string :

I'm very sad because this module is very important for my homework. Please help me.
I'm trying to insert data into a table from two sources (a table and form controls) at the same time.
--this data from the tradeitem table and is inserted into the selections table
--based on the variable @builderid --no problem it works fine as is
INSERT INTO Selections ([TradeItemID], [TradeID], [ProductName], [OrigSalesPrice], [RevSalesPrice])
SELECT [TradeItemID], [TradeID], [TradeItem], [Price], [Price]
FROM tradeitems
WHERE BuilderID = '1'
However, I need these also to pull from the form controls
--These variables will pull from form controls and need to be associated
--with each record added to the seleciton table
INSERT INTO Selections ([UserDataID] = '1', [DefaultQty] = '0')
--How do I get these combined into one statement so I get the following result?
TradeItemID
TradeID
ProductName
OrigSalesPrice
RevSalesPrice
UserDataID
DefaultQty

I have a question about loading data on the page lode event. The question is more conceptual then how to.
Using C#, I would like to make a call to a SQL 2000 Server, with the use of a stored procedure return one row with eleven fields. Then use the data to fill five different controls. There is no manipulation of the data it is just presented as information. With a DataReader and the GetValues method using the resultant array I can fill the controls (or can I), or with a DataSet and the Load method do the same thing. Now this code can be placed in the code behind page or it can be implemented in a class. This is the only page that uses this combination of fields and controls; however I would think a more generic call to the data could be made then pick and chose the fields as needed. What process makes the most sense? Is what I just described even possible (as yet I haven’t tried it)?
As always thanks in advance for any thoughts, comments, and suggestions.
Hi!
I am creating a scheduling web application. I have managed to insert data into the database. The code is as follow:
Dim insertSQLDatasource As New SqlDataSource()
insertSQLDatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ScheduleConnectionString").ToString
insertSQLDatasource.InsertCommandType = SqlDataSourceCommandType.Text
insertSQLDatasource.InsertCommand = "INSERT INTO Demo_Theatre_DB (StartTime, EndTime, CompanyName, Purpose, AccountManager, Presenter, ColorCode, Status, Comments) VALUES (@StartTime, @EndTime, @CompanyName, @Purpose, @AccountManager, @Presenter, @ColorCode, @Status, @Comments)"
insertSQLDatasource.InsertParameters.Add("StartTime", StartTimeTextBox.Text)
insertSQLDatasource.InsertParameters.Add("EndTime", EndTimeTextBox.Text)
insertSQLDatasource.InsertParameters.Add("CompanyName", CompanyNameTextBox.Text)
insertSQLDatasource.InsertParameters.Add("Purpose", PurposeTextBox.Text)
insertSQLDatasource.InsertParameters.Add("AccountManager", AccountManagerTextBox.Text)
insertSQLDatasource.InsertParameters.Add("Presenter", PresenterTextBox.Text)
insertSQLDatasource.InsertParameters.Add("ColorCode", ColorDDL.SelectedValue.ToString)
insertSQLDatasource.InsertParameters.Add("Status", StatusRadioButtonList.SelectedValue)
insertSQLDatasource.InsertParameters.Add("Comments", CommentTextBox.Text)
Try
insertSQLDatasource.Insert()
Catch ex As Exception
Panel1.Visible = True
InsertMsgLabel.Text = ex.Message.ToString
Finally
insertSQLDatasource = Nothing
End Try
Now I am trying to select the values for a particular event. For example, if the user selects an event with id 40, the values that corresponds to that row will be read and filled into the respective controls. I tried the following code, but doesn't work.
Dim sqlConn As SqlConnection = New SqlConnection("ScheduleConnectionString")
Dim com As SqlCommand = New SqlCommand("SELECT * FROM Demo_Theatre_DB WHERE ID=@ID", sqlConn)
sqlConn.Open()
Dim r As SqlDataReader = com.ExecuteReader()
While r.Read()
StartTimeTextBox.Text = r("StartTime")
EndTimeTextBox.Text = r("EndTime")
CompanyNameTextBox.Text = r("CompanyName")
PurposeTextBox.Text = r("Purpose")
AccountManagerTextBox.Text = r("AccountManager")
PresenterTextBox.Text = r("Presenter")
ColorDDL.SelectedValue = r("ColorCode")
StatusRadioButtonList.SelectedValue = r("Status")
CommentTextBox.Text = r("Comments")
End While
I hope someone can help me with this.
Your help will be appreciated.

Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having. Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!

I am having problems running a stored proc from an aspx.cs file. Basically I want to extract data from webForm controls and create a new record in a DB table. I have watched the "Getting Started" videos on thi site, and the only difference between my code and the code of the demonstrator is the connection string. My conn string:- dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings["ProjectTblConnString"].ConnectionString;Demonstrator conn string:- dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings("ProjectTblConnString");When I debug with the string as shown by the demonstrator the error list reports that ConnectionStrings is a property and I am trying to use it as a mothod, which is fair enough, but I am just confused as how it worked for the demonstrator and not myself. When I debug with the code I used above I get no error, but nothing is inserted in the DB.Also, it looks as if the only class in my aspx.cs file that is actually being executed is PageLoad() - the remainder of the code seems to be ignored.

Hi,I’m new to SQL Express, but I have created a table and a stored proc to populate it.I have dragged the table into a form so I can view the data in a GridView.I have added a button to add new rows to the table. All the above works fine, except when I hit add, the data gets added, but the GridView doesn’t update and show the new data. Is there some code I can add to the add button that also refreshed the GridView? ThanksMike
View 2 Replies View RelatedI have a few Stored procedures that return values, some need parameters passing and others don't.
Up to now to access that data in a Web App I have called this procedure using VB after seting up a data block etc.
However I notice that the Web Developer express edition has some tools that look like they should help. I have used the in-built tools to create a SQL data source linked to a details view. I then specified that this should connect to my database (sql2005 hosted) and then specified Custom SQL or Stored procedure.
From the drop down I can then select the SP that purely returns values. When I try to test this query I get an error to say that the query did not return any data tables.
Is there a way to get values returned from a SP in this way?

Hi,I want to add Sql data dependency in GridView. Whenever any changes in database, same will be reflected in Grid. but this should work in both Sql server 2000 and sql server 2005. And when we click on "Pause" button it should stop refreshing.
PAUSE
Index
First name
Last Name
Address
1
Xyz
Abc
Asdf, asdf
2
Pqr

Sdsa, asad
Is there any way to fulfill this kind of requirement? Please suggest me optimal solution to do this.Regards,Mustakim Mansuri
I have a products table in a Sql Server 2005 database. One of the fields contains the products attributes in xml. The most commonly used attribute is color. An element of color is inventory. This is the only way I could think of to maintain inventory numbers of each color of each product using someone else's (opensource) code. An example of an attribute field would be <?xml version="1.0"?> <ArrayOfAttribute
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Attribute>
<Name>Color</Name> <Description>Shown in
Black</Description> <Selections> <AttributeSelection>
<FormattedValue>483 - Black</FormattedValue> <Value>483 -
Black</Value> <Inventory>25</Inventory>
</AttributeSelection> <AttributeSelection> <FormattedValue>484
- Lt. Tan</FormattedValue> <Value>484 - Lt. Tan</Value>
<Inventory>15</Inventory> </AttributeSelection>
<AttributeSelection> <FormattedValue>485 -
Pink</FormattedValue> <Value>485 - Pink</Value>
<Inventory>17</Inventory> </AttributeSelection>
</Selections> <SelectionType>SingleSelection</SelectionType>
</Attribute> </ArrayOfAttribute> How can I read this into the gridview control so that it makes sense to the user?Diane
I have a webform that I am wanting to display data from a database. Right now I am using the gridview but for future purposes when it comes to maintenance what would be the easiest way to do updates? For example, if I add a new record into the database I would like the webform to automatically update itself to show all the records including the new record I added. Do I need to use a "table" and somehow connect it to a database? Do any stored procedures need to be created? Suggestions/ideas/codes help help help would be verrrry much appreciated!!! Also I am using MS Server 2003 and C# as the programming language. Thank you!!!!
View 9 Replies View RelatedHello all,
I am trying to modify the output of a SELECT statement in a VB asp.net page that pulls data from a SQL DB. I only need to modify one column in the gridview, but I'm having some issues.
Here is the situation:SELECT TOP 24 ID, RecID, Timestamp, Answered, Holds, Dropped, Waits, Voicemail, Busied, LiveWaitsFROM mTrafficORDER BY Timestamp DESC
The Timestamp column returns a number value (i.e. 564566).In terms of a date, 564566 doesn't mean anything to the user, so I need to convert this number into a recognizable and accurate date.
The formula I need to implement is Timestamp/1440 - 1
The following SELECT statement returns the number as a date, but makes all records the same date:
SELECT TOP 24 ID, RecID, Convert(datetime, Timestamp/1440 + 1) as Timestamp, Answered, Holds, Dropped, Waits, Voicemail, Busied, LiveWaitsFROM mTrafficORDER BY Timestamp DESC
What do I need to do to implement this function dynamically into my gridview?
Thanks in advance!

Good Day, Please help me, I have a database that looks like this, Building No. Floor No. Room No. Customer Name Appliances Appliances Codea 1 01 John TV 12a 1 02 //up tob 20 10 james Ref. 22b 20 10 joe Microwave 15 //and soon so if you would notice some rooms are vacant, as it usually happens, the buildings, floors and rooms are fixed except for the customers and the appliances. so at first i made this gridview and display this data in this manner:Customer Location (Building + floor) total rooms Used Rooms Available rooms A1 2 1 1 B2010 2 2 0 so if you would look at the table above, it just SUM up all tenants in a specific Location then Group it by Customer location,but i need to add the appliances in a different format like this: Customer Location (Building + floor) total rooms Used Rooms Available rooms TV Ref Microwave
A1
2 1 1 tick
B2010
2 2 0 tick tick so this is what i need to show, i already have done the first table (w'o appliances) but how can i make this second table?? please help me, SALAMAT PO.,Thanks
I have a GridView that gets data from an SqlDataSource. It works fine, but now when I want to filter the results and add more parameters to my sql query, nothing happens. My initial select statement in the SqlDataSource contains only 2 parameters, so now when a user clicks a Button, onclick I call a function that is supposed to change the select statement of the SqlDataSource, add 2 more parameters taken from 2 controls, and then update the GridView. This is what I use: dataSource.SelectCommand = "new select command here"; dataSource.SelectParameters.Add("State", txtState.Text); dataSource.SelectParameters.Add("City", txtCity.Text); grid.DataBind(); It compiles, but when I click the button to filter the results, the GridView always looks the same as if nothing happened. I do not know if this is the right way to do it, or am I on the wrong track? Help is appreciated. Thank you in advance.
View 2 Replies View RelatedThe function that is supposed to delete a row, is not working. The function is called, and the windows is refreshed, but the row is not deleted.Can anyone see anything wrong with this code:public static void DeleteBlog(int original_BlogID) { string insertCommand = "DELETE FROM Blog WHERE BlogID = @BlogID"; SqlConnection myConnection = new SqlConnection(Blog.ConnectionString); SqlCommand command = new SqlCommand(insertCommand, myConnection); command.Parameters.Add(new SqlParameter("@BlogID", original_BlogID)); myConnection.Open(); command.ExecuteNonQuery(); myConnection.Close();}
View 3 Replies View RelatedHi,
I think the title explains it all really. I cannot configure the SqlDataSource to add Insert, Update and Delete statements - not through the wizard anyway.
The view combines two tables, each containing 3 columns. I have tried using different combinations of columns, and ended up selecting all of them (making sure the foreign key column of the first table was given a different alias to the primary key column of the second table) but I still cannot enable editing.
Cheers,

Hello, i currently have a gridview that is populated with data from a SQLServer datasource. I have put an output mask in the select statement, so the date and time attributes are displayed in the format i prefer them to be in. SELECT PatientNo, ConsultantName, HospitalName, CONVERT (varchar, Date, 101), CONVERT (varchar, Time, 8) FROM [Appointment];
However when i click the 'edit' link for a record in the gridview, i am unable to edit the date/time attributes and when i click update to confirm any changes to the other attributes, the values in the date/time attributes are emptied. How can i solve this update problem. I'm guessing i need to configure my SQL UPDATE statement, but bit stuck how i do this. Please help!
Thanks,
James
