Having Trouble Configuring The SqlDataSource Control's Update And Insert Commands
Jul 24, 2007
I've just finished configuring the SELECT command for the SqlDataSource in my ASP.NET 2.0 web app. It works fine and runs against a SQL Server 2005 database, using a stored procedure that I've written.
So, then I went to configure the SqlDataSource for the UPDATE and INSERT commands, and I've written two SP's for those as well. In the designer the second form of the wizard asks for the Select statement. I've already given that for the SELECT statement in the third form, and I also select the INSERT tab to specify the SP I want to use for inserting data and the UPDATE tab to specify the SP I want to use for updating data. However, there appears to be no way that I can specify what the parameters are supposed to be for anything other than the SELECT command, through the designer. Is that correct, or have I missed something?
When I configure a SQLDataSource control I want the following where clause... WHERE (RegionID = @RegionID AND DistrictID IS NULL AND CampusID IS NULL) OR (DistrictID = @DistrictID AND CampusID IS NULL ) OR(CampusID = @CampusID AND UserRole = 'CampusAdmin') OR (CampusID = @CampusID)but it gets reformated as.... WHERE (RegionID = 'Region10') AND (DistrictID IS NULL) AND (CampusID IS NULL) OR (DistrictID = 2) AND (CampusID IS NULL) OR (CampusID = '999999103') AND (UserRole = 'CampusAdmin') OR (CampusID = '999999103')I don't think these are functionaly equivelant, are they?If not how do I stop the 'wizard' from reformatting the SQL where clause?Thanks
I can select the tables and fields, but when I click on Advanced the Check Box to Create the Commands is not available. they are dimmed out. Why is this happening, is it a setting that I have missed. Any help is appreciated.
Hi, I'm reasonably new to ASP.NET 2.0 I'm in my wizard_FinishButtonClick event, and from here, I want to take data from the form and some session variables and put it into my database via a stored procedure. I also want the stored procedure to return an output value. I do not need to perform a select or a delete. For the life of me, I can't find a single example online or in my reference books that tells me how to accomplish this task using a SqlDataSource control. I can find lots of examples on sqldatasources that have a select statements (I don't need one) and use insert and update sql statements instead of stored procedures (I use stored procedures). I desperately need the syntax to: a) create the SqlDataSource with the appropriate syntax for calling a stored procedure to update and/or insert (again, this design side of VS2005 won't let me configure this datasource without including a select statement...which I don't need). b) syntax on how to create the parameters that will be sent to the stored procedure for this sqldatasource (including output parameters). c) syntax on how to set the values for these parameters (again...coming from form controls and session variables) d) syntax on how to execute, in the code-behind, the stored procedure via the sqldatasource. If anybody has sample code or a link or two, I would be most appreciative. Thank you in advance for any help!
I've had a look at this thread - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=104399&SiteID=1 - but it's a bit old so I thought I'd try to clarify a couple of things.
I have a data flow which inserts or updates a table in a SQL 2000 database.
The insert is done via an OLE DB destination and the update is done via an OLE DB Command.
As stated in the previous thread, when these commands run concurrently issues arise with blocking etc.
The only way I've managed to get around it is by setting the access mode of the insert to OpenRowset.
So 2 questions:
1) Does anyone know how this problem occurrs and what the best way to get around it is?
2) Are there issues around NOT using the fast load options - I've read stuff about the double-byte character set etc but I admit I don't quite understand it.
I issue an insert statement to the db. While I am getting a return value of 1 (1 row was affected) the values never show up into the db when I open the DB in access. However, I can see the data when it does an SQL select inside the program. So for instance, I do an insert into ORDER values (1, 12, 5.99). (1 = item ID, 12 = quantity, 5.99 = price). I then do a select * from Order, and I get those values back. When I open the DB in access, in between doing the insert and the select, I dont see the values there either. It is like it is making a temporary copy of the DB in memory during the execution only. When I close the program and re-F5, the data is no longer there. Maybe we need some kind of commit transaction? What am I doing wrong? I am using VB.Net 2005/MS Access 2003. Here is the relevant code :
Private m_Connection As OleDbConnection
''' <summary>
''' Defines the path to the database.
''' </summary>
''' <remarks></remarks>
#If CONFIG = "Debug" Then
Public Const DB_PATH As String = "DBsDB_Test.mdb"
#ElseIf CONFIG = "Release" Then
Public Const DB_PATH As String = "DBsDB_Production.mdb"
#End If
Sub connect(ByVal p_path As String) Implements IPartyDBase.connect
Dim connect_string As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & p_path
m_Connection = New OleDbConnection(connect_string)
Throw New Exception("Bad addStockToDB into Stock " & tempInt)
End If
End Sub
Sub anotherSub
p_dbase.connect(PartyDBaseAccess.DB_PATH)
p_dbase.someSub()
p_dbase.close()
End Sub
Edit : During execution, looking under bin/debug/DBs, there is a copy of the database that has all the transactions I did during execution... but the actual DB isnt being updated/copied over.
Ok, this seems really straightforward, but I'm completely lost. I created a sqldatasource control that uses an INSERT stored procedure. I can click on test it tests just fine, inserts everything into the database.Now, I want this sqldatasource control to fire when a button is clicked, but I have no idea how to do this, I looked at the parameters and cant find an execute or anything like that to use. Let me know how to execute this sqldatasource, it'd really help me out. I know you can do EVERYTHING in the code behind file, but I'm rather new to VB and I'm probably gonna save that for another day. Here's what I have now:basic sqldatasource : <asp:SqlDataSource ID="SqlProcDS" runat="server" ConnectionString="<%$ ConnectionStrings:pubsConnectionString %>" InsertCommand="ins_test" InsertCommandType="StoredProcedure" SelectCommand="ins_test" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:ControlParameter ControlID="TextBox1" Name="a" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox2" Name="b" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox3" Name="c" PropertyName="Text" Type="String" /> </SelectParameters> <InsertParameters> <asp:Parameter Name="a" Type="String" /> <asp:Parameter Name="b" Type="String" /> <asp:Parameter Name="c" Type="String" /> </InsertParameters> </asp:SqlDataSource>in the vb file : Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click 'Somehow execute sqlProcDS here?!End Sub
Hi, I need to UPDATE the IP Address of a newly created user into a table (the value is currently set to default - " Not Available"), and I really dont know the syntax required to do this. So far I've derived all the variables needed using the following code: protected void ContinueButton_Click(object sender, EventArgs e) { //Get the ip address and put it into the customer table - (the instance of this user now exists) MembershipUser _membershipUser = Membership.GetUser(); Guid UserId = (Guid)_membershipUser.ProviderUserKey;<--------------------------------------------------------------I can see the UserId here if I pause the prog SqlDataSource customerDataSource = new SqlDataSource(); customerDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); customerDataSource.UpdateParameters.Add("IPAddress", Request.UserHostAddress.ToString());<---------------------------------------I can see the IPAddress here customerDataSource.UpdateCommandType = SqlDataSourceCommandType.Text; what next I've not got a clue as to what to write next. There is a try / catch statement after this using : rowsAffected = customerDataSource.Update(); which remains at 0 no matter what I try. Any help greatly appreciated.
Hi, I am a newbie in using ASP.NET 2.0 and ADO.NET. I wrote a hangman game and want to record statistics at the end of each game. I will create and update records in the database for each authenticated user as well as a record for the Anonymous, unauthenticated user. After a win or loss has occurred, I want to programmatically use the SQLDataSource control to increment the statistics counters for the appropriate record in the database (note I don't want to show anything or get user input for this function). I need a VB.NET codebehind example that will show me how I should set up the parameters and update the appropriate record in the database. Below is my code. What happens now is that the program chugs along happily (no errors), but the database record does not actually get updated. I have done many searches on this forum and on the general Internet for programmatic examples of an update sequence of code. If there is a tutorial for this online or a book, I'm happy to check it out. Any help will be greatly appreciated.

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:
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, KB
I am trying to Insert or Update a record in MSSQL with a datetime variable which is modified using the DateAdd function.
Basically, I have a table of Coupons which need to expire 'x' days in the future. When I use GetDate() for the Issue Date, I have no problems. But then, when I use DateAdd to return a date in the future, I can not Insert or Update this result into the record.
I get various errors having to do with type mismatch or function not found, etc.
Hello, I am trying to use the forms view control to do a simple web app. My issue is, I cant get the connection to automatically generate insert, update and delete statements. I tried to do this manually but I always get an error. I have read that I need all the keys selected--this still didnt work. I have about 6 tables picked in my view, and if I pick one of them then this advanced feature works. I have the primary keys selected. here is my saved view. this is in SQL 2000.

I have 2 Gridviews and a DetailsView for each GridView. The first Gridview and DetailsView work fine and I can Insert, Delete and Update the DetailsView just fine. However the second Gridview/DetailsView will only let me Insert but not Delete or Update. When I click on the "Delete" button it just ignores me. If I do an "Edit", when I try to click on the "Update" button it is ignored again and I have to click on "Cancel". I don't get any error messages...
I’m trying to create a sqlDataSource using the wizard, I can get the select statement, the here clause and the order by clause but when I click on the Advanced button the options to generate the insert, update and delete statements are not available. Does anyone know what am I doing wrong?
I have an SQL data source on my page and I select "Table". On the next screen I pick the fields I want to show. Then I click the "Advanced" button because I want to allow Inserts, updates and deletes. But its all greyed out abd I can't check this option. The UID in the connection string I am connecting under has the correct permissions in SQL server to do inserts, update and deletes too. Anyone know why it would be greyed out? The connectionstring property in the aspx code is dynamic but this shouldn't be the reason because I have used this before with success

Hi,I'm new to ASP.NET and having a problem configuring the SqlDataSource control. I am using the standard ASP.NET 2.0 "aspnetdb" database to manage user accounts. The problem is this:When using the wizard to configure my SqlDataSource control, the option to auto-generate the Insert/Update/Delete SQL statements are grayed out. I've searched this forum and found that this can be a symptom of no primary keys in the tables. However, there are primary keys (UserId), which is the default schema as generated by asp.net (aspnet_regsql.exe). When I use the wizard, I make the following choices:How would you like to retrieve data from your database?-> Select "Specify columns from a table or view"-> Select the "vw_aspnet_MembershipUsers" view from the "Name:" drop-down list-> Select "UserId", "Email", "UserName" from "Columns:"After this, still no option to auto-generate I/U/D statements. Any thoughts on why this isn't working??? Thanks,Leah.
In a web site the user has to choose one out of several sql tables to deal with. He will then be allowed to view the selected table data through a GridView, to insert a new row into and to update a row in the selected table by means of an array of TextBoxes created dynamically on the base of the selected table. I think it is possible to solve the problem fully by properly configuring at run time an SqlDataSource. I have solved the issue of data display by declaring in the code behind within the OnPageLoad sub the following: SqlDataSource1.SelectCommand = "Select * FROM " & selectedTable While for the GridView1 I have added the selected table columns to the columns collection as follows: for i=0 to ColumnCount-1 Dim cac As BoundField = New BoundField cac.HeaderText = HeaderNamesArray(i) cac.DataField = ProductNamesArray(i)Me.GridView1.Columns.Add(cac) next I have difficulty on how to do similar declarations for the insertcommand and update command.
I have several Sql Tables, each containing more than 100 fields, on which I need to perform display operation through GridView, Insert and Update through an array of dynamically created and databound TextBoxes. I would like to use a single page to manage all Sql Tables on the basis of the name of the specific one invoked by the user. In order to achieve that, I need to dynamically configure the SqlDataSource Web Control present on the page for each Sql Table. In particular I need to generate at runtime the InsertCommand and the UpdateCommand. On how to do it I have no idea. Federico
Hello, I have specified a default database in my web.config like this: <dataConfiguration defaultDatabase="scsLocal"/> <connectionStrings> <add name="scsLocal" connectionString="server=DRLSWARTEBRV;database=SCS;uid=******;password=******;" providerName="System.Data.SqlClient"/> </connectionStrings> Now I would like to configure a SQLDataSource control to use this default database, yet it prompts me for a connectionstring. I know I can program it in the code behind file (if I ommit connection string, it will use the default), but then I can make no use of the wizard for configuring the SQLDataSource which would safe me a lot of coding. Is there a way to configure the SQLDataSource to use the default database that is specified in the web.config? Thanks! Veerle
I'm creating a report with a Datetime parameter. There's no available values, so the calendar control comes out automatically when I run/preview the report. Now, when I select the date in my calendar control, say for example I select 2/5/07 (2nd of May) and run the report, it gives me data from 5th of Feb. Can anyone help me with this date format problem ???
Not sure if it's related to my problem, I did edit the language tag in the XML source code of my report to have en-AU so that the dates field is showing in the correct dd/mm/yyyy format.

Do you have to use the sqldatasource in conjuction with another control like gridview or dropdown list? I'd like to check to see if a record exists in one table before inserting data into another.

I have created a SqlDataSource control, which is 'connected' to my SQL server.Now my question is how i can put data in the database throw the control, and read data from it. I've read the site, but it's still unclear for me..Greetings!

Hello, what i want is simple. This is a simple forum, it has several topics (that the users can create), when a user create a topic, its stored in forum_topics. The user can then view the topic and post a response that is store in forum_answer, the user can also add this to his favorite list, forum_favorites is simple, contains a TopicID that refers to the topic, a username of the user that has the topic on his favorite list and a auto increment id to be able to delete specified topic favorites. Now my question is: when a user posts a answer to Topic X, i want a predefined message to be sent to post_inbox for all the users that has Topic X in their favorite list. How can i get MS SQL 2005 to get all the users from Topic X and then loop thru them and insert a new post into post_inbox?
