I am trying to update a field in gridview. My update is not working, sort of. The original value is being updated with a NULL value when I click on the update button.
here is my code
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource2" AutoGenerateEditButton="True" DataKeyNames="rqt_id">
UpdateCommand="UPDATE [rqt_data] SET [rqt_title]=@rqt_title WHERE [rqt_id] = @rqt_id" >
<asp:Parameter Name="rqt_title" Type="String" />
the field rqt_title is set up as a NVarChar(25) in the db. I can't specify that for the Type property. Could that be the issue?
thx

Hi All, I am new to development of asp. I have an SQLDataSource set as the data source for a grid view. When I click on the edit link in the Gridview, change the data, and click update, the old data is still displayed in the row. I found exact same issue as here -- http://forums.asp.net/thread/1217014.aspx Solution in the above thread is to add this { if (reader != null) reader.Close(); } conn.Close(); How do I apply above solution in my situation ?

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.
When I attempt to update using a stored procedure I get the error 'Incorrect syntax near sp_upd_Track_1'. The stored procedure looks like the following when modified in SQLServer: ALTER PROCEDURE [dbo].[sp_upd_CDTrack_1] (@CDTrackName nvarchar(50), @CDArtistKey smallint, @CDTitleKey smallint, @CDTrackKey smallint) AS BEGIN
SET NOCOUNT ON; UPDATE [Demo1].[dbo].[CDTrack] SET [CDTrack].[CDTrackName] = @CDTrackName WHERE [CDTrack].[CDArtistKey] = @CDArtistKey AND [CDTrack].[CDTitleKey] = @CDTitleKey AND [CDTrack].[CDTrackKey] = @CDTrackKey END But when I use the following SQL coded in the gridview updatecommand it works: "UPDATE [Demo1].[dbo].[CDTrack] SET [CDTrack].[CDTrackName] = @CDTrackName WHERE [CDTrack].[CDArtistKey] = @CDArtistKey AND [CDTrack].[CDTitleKey] = @CDTitleKey AND [CDTrack].[CDTrackKey] = @CDTrackKey" Whats the difference? The storedproc executes ok in sql server and I guess that as the SQL version works all of my databinds are correct. Any ideas, thanks, James.
I've got a listbox that displays a list of employee's names. The employee number is the value stored in the listbox. I then have a vaccinations gridview that displays all the vaccinations received by the selected employee in the listbox. For some reason, when I click edit and modify a record and then click update it doesn't want to actually update the record. It just appears to do a postback and redisplay the record without any changes. My sqldatasource control is configured as follows: SelectCommand="SELECT * FROM [tblVaccinations] WHERE ([EmpNum] = @EmpNum)" @empnum = mylistbox.selectedvalue the update command is as follows: UpdateCommand="UPDATE [tblVaccinations] SET [EmpNum] = @EmpNum, [VacType] = @VacType, [VacIssueDate] = @VacIssueDate, [VacExpDate] = @VacExpDate, [VacInstitution] = @VacInstitution WHERE [VaccinationNum] = @VaccinationNum"
I have a gridview that is tied to a SQLDataSource control which is inside an update panel. What I'm trying to accomplish is when the page is loaded the gridview is filled from the SQLDataSource. I have some textboxes also on the page so that the user can add new items to the gridview. The update panel trigger is tied to my code behind page through a button click which added the new data to the DB with an INSERT statement. Since the gridview was inside the update panel I thought when I placed the new data into the DB and the update panel caused the portion of the page that holds the gridview to refresh that the gridview would show the newly added data but it is not. I am missing something but I do not know what. I tried adding a gridview1.databind() and SQLDataSource1.DataBind() but niether caused the update of the gridview as I had hoped. Thanks for any of your help. Ty
Hi all I have a GridView on an aspx page, that is enabled for editing, deletion and sorting. In the Page_Load event of the aspx page, i add a SqlDataSource to the page, and bind the source to the GridView. When i click the update, or delete button, it makes a PostBack, but nothing is affected. I'm sure this has got something to do with the parameters. First, i tried having the GridView.AutoGenerateColumns set to True. I have also tried adding the columns manually, but no affect here either. The code for setting the commands, and adding the SqlDataSource to the page are as follows: string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName; string selectCommand = "SELECT * FROM rammekategori"; SqlDataSource ds = new SqlDataSource(strProvider, strConn, selectCommand); ds.ID = "RammeKategoriDS"; ds.UpdateCommand = "UPDATE rammekategori SET Kategoribeskrivelse = @Kategoribeskrivelse WHERE (Kategorinavn = @Kategorinavn)"; ds.DeleteCommand = "DELETE FROM rammekategori WHERE (Kategorinavn = @Kategorinavn)"; Parameter Kategorinavn = new Parameter("Kategorinavn", TypeCode.String); Parameter Kategoribeskrivelse = new Parameter("Kategoribeskrivelse", TypeCode.String); ds.UpdateParameters.Add(Kategorinavn); ds.UpdateParameters.Add(Kategoribeskrivelse); ds.DeleteParameters.Add(Kategorinavn); Page.Controls.Add(ds); SqlDataSource m_SqlDataSource = Page.FindControl("RammeKategoriDS") as SqlDataSource; if (m_SqlDataSource != null) { this.gvRammeKategorier.DataSourceID = m_SqlDataSource.ID; } As mentioned - no affect at all! Thanks in advance - MartinHN
<!-- Trying to create a GridView Survey form: Hi [User] Do you have these assets? [Gridview] Tag Number Response 123 [Yes ] [No] [Comments textbox] 234 [Yes ] [No] [Comments textbox]

If I run it manually on sql server, it fails until the directory column is removed. The type is varchar(50), with a uniqueness constraint. However, this is same type as the title column, which doesn't have this problem. Thanks, Jessica

I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn) 'Dim cmd As New SqlCommand("pContact_Add", cn)
Catch ex As Exception Label1.Text = ex.Message End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
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 have a GridView dispalying from a SQLServerDataSource that is using a SQL Select Union statement (like the following):
SELECT FirstName, LastNameFROM MasterUNION ALLSELECT FirstName, LastNameFROM CustomORDER BY LastName, FirstName I am wondering how to create Update and Insert statements for this SQLServerDataSource since the select is actually driving from two different tables (Master and Custom). Any ideas if or how this can be done? Specifically, I want the Custom table to be editable, but not the Master table. Any examples or ideas would be very much appreciated! Thanks, Randy
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!
