Want Error Message To Appear When No Database Results Were Returned In GridView, Also Other GridView Issues.

Jun 12, 2008

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!

Refreshing Data In GridView

Sep 18, 2006

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

Gridview && SQL Data Source

Jul 22, 2007

I 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?
Regards
Clive

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]?

How To Use Xml Data From A Sqlserver Table In A Gridview

Jan 6, 2008

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

Mar 19, 2008

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!!!!

Changing Format Of Data In Gridview Using VB

Mar 24, 2008

Hello 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!
 
Chris

Display Data In A Gridview In A Little Diiferent Way

Apr 25, 2008

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

Filter Data And Update GridView

May 11, 2008

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.

Why Can't I Enable Editing On A Gridview That Gets It's Data From A View Through An SqlDataSource?

Nov 22, 2007

Hi,
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,
Patrick

Error Editing Data Records In Gridview When Using Convert Function.

Jan 24, 2008

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

Asp.net Page Is Unable To Retrieve The Right Data Calling The Store Procedure From The Dataset/data Adapter

Apr 11, 2007

I'm trying to figure this out
 I have a store procedure that return the userId if a user exists in my table, return 0 otherwise
------------------------------------------------------------------------
 Create Procedure spUpdatePasswordByUserId

@password varchar(20)
AS
Begin
Declare @userId int
Select @userId = (Select userId from userInfo Where userName = @userName and password = @password)
if (@userId > 0)
return @userId
else
return 0
------------------------------------------------------------------
I create a function called UpdatePasswordByUserId in my dataset with the above stored procedure that returns a scalar value. When I preview the data from the table adapter in my dataset, it spits out the right value.
But when I call this UpdatepasswordByUserId from an asp.net page, it returns null/blank/0
 passport.UserInfoTableAdapters oUserInfo = new UserInfoTableAdapters();
Response.Write("userId: " + oUserInfo.UpdatePasswordByUserId(txtUserName.text, txtPassword.text) );
 Do you guys have any idea why?

Retrieve Text File Data In SSE For Data Acquisition System

Oct 24, 2007

Hey All,
I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.

Retrieve Data

Mar 18, 2008

Hello,

Before I ask a question, I am visually impaired and cannot read printed words only on a screen. I am 51 years old and have been coding professionally since I was 23 (yes that long). I have four apps on the market and run a small consultancy company in the UK and my SQL knowledge is scant. I have read two books on the subject and thought I had an idea on how SQL works.

I used to belong to another forum but they gave me a hard time so please go easy on me.

I developed an ADO app ages ago and remembered some of it ...

I have four tables (the following is a simplified version of the real thing)

MainTable (Contact data like name address etc. 23 fields)
Towns (Two fields TownUIN and TownName)
Counties (Two fields CountyUIN and CountyName)
Countries (Two fields CountryUIN and CountryName)

My database is normalised to 3NF and contains no duplicate or redundant data.

My problem ...

Sample data

Main:
MainUIN MainName MainTown
1000 Fred Bloggs 1
1001 Fred Smith 2

Towns:
TownUIN TownName
1 Bradford
2 Leeds

SELECT MainName,MainTown FROM Main WHERE MainUIN=1000 returns
'Fred Bloggs' 1 (the TownUIN)

I want ...
'Fred Bloggs' 'Bradford'

It was suggested I use
SELECT MainName,MainTown FROM Main,Towns WHERE MainUIN=1000 AND TownUIN=MainTown
This returned 'Fred Bloggs' 'Bradford' but was slow.

My question is what am I doing wrong?

I am using SQL Server 2005 Express with VB.Net 2005 on Vista Business and XP.

I am sorry my SQL knowledge is weak please dont get angry just tell me the basic thing that I do not know.

How To Retrieve Data As XML From SQL Database

Feb 28, 2007

Hi,
I have a website which is designed to search for employee information. I have the search system working which does exactly what I want to, but as an added feature I want there to be a button which, when someone clicks on it, it takes whatever the previous search was and generates a set of data in XML format which is based on the results. For example:
User searches for all entries with Forename = John; Results are listed in a gridview as per expected.
User then presses button with XML on it, and page pops up with just the XML output on it, i.e. whatever results are on the gridview but in a nested XML format
<records>    <record>       <Forename>John</Forename>       <Surname>Smith</Surname>       <Email>j.smith@blah.com</Email>       <Ext>1234</Ext>       <DeptList>History</DeptList>    </record></records>
I have created a stored procedure which will take the parameters from the search boxes and return the above information, but I don't know if this is the best way. Here it is for those interested:
CREATE PROCEDURE ps_record_SELECT_NameSurnameEmailExtDeptasXML
@Forename varchar(50),
@Surname varchar(50),
@Email varchar(50),
@Ext varchar(4),
@DeptList varchar(50)
AS
SELECT Forename, Surname, Email, Ext, DeptList
FROM dbo.record
WHERE Forename LIKE COALESCE(@Forename,Forename) AND
Surname LIKE COALESCE(@Surname,Surname) AND
Email LIKE COALESCE(@Email,Email) AND
Ext LIKE COALESCE(@Ext,Ext) AND
DeptList LIKE COALESCE(@DeptList,DeptList)
FOR XML AUTO, ELEMENTS
If someone could be kind enough to help me out with this, I'd be really grateful.
Many thanks,
Tom

Right Way To Retrieve Data From Sql-server

Mar 19, 2007

Last night I face performace problems in web site. I got like 100 000 users and site fails because of sql-connections.
Currently I'm making a new connection for every query, and my code looks like this:Public Shared Function executeQueryReturnDataset(ByVal strsql As String) As DataSet
Dim sqlConnection As New SqlConnection(Connstr)
Dim sqlCommand As New SqlCommand(strsql, sqlConnection)
Dim sqlDataSet As New DataSet

Try
sqlConnection.Open()
Dim myDataAdapter As New SqlDataAdapter
myDataAdapter.SelectCommand = sqlCommand
myDataAdapter.Fill(sqlDataSet)
Catch e As Exception
Console.Write(e.ToString())
Finally
sqlConnection.Close()
End Try
Return sqlDataSet
End Function I was wondering would it be better to save an instance from connection object to memory and use that same connection for all querys?

Retrieve Data From SQLDataSource

Jan 23, 2008

Background:I am using Visual Studio 2005 Standard SP1 to create an ASP.NET website that accesses an SQL 2005 database.  I am using vb.net as well.I am passing an ID in a query string from one page to the next, where I retrieve it using an SQLDataSource.  The data will only be one row; it is returning customer information.Problem:I need to be able to get specific fields from the SQLDataSource and populate some textboxes.  Honestly, I'm not really sure where to begin.  For the sake of argument, let's say that I am working with this:'My TextboxDim LastName As Textbox'My SQLDataSource (filtered by query string using the customer's ID to only get 1 customer's information at a time)SQLDataQuestion:So, how would I go about retrieving the lastname field from SQLData and inserting it into the textbox LastName?Thanks,    J'Tok

How To Retrieve Data From SQL Server?

Mar 14, 2006

Let us suppose that there are 900 rows in One table, and that table contains neither primary key, nor Identity column.
How can I retrieve all the roows from 201 to 250?(like the middle limits)
In oracle there is a property called RowID, but is there any such item in SQL server?

How Do I Retrieve Sql Data In A Distinct-like Way?

Jul 23, 2007

I wonder how to get top 1 row per account number. Let's say I have

--snip--
IDENTITY_ID | ACCT_NUMBER
0001 | 1111-2222
1001 | 1111-2222
2002 | 2222-0000
3003 | 2222-0000
4004 | 1111-2222
--snip--

I used the SQL-Query here


Code:


SELECT * FROM BACKUP_LOG ORDER BY IDENTITY_ID DESC
[code]

Since they are in descending order by IDENTITY_ID, so I only want to get 1 distinct account number somehow.. Like this...

[code]
4004 | 1111-2222
3003 | 2222-0000



I couldn't figure it out.

Thanks...
