Then I have several methods attached with following events Get video of hundreds of ASP. On Row Editing - Edit Record On Row Cancel Edit - Cancel Record On Row Updating - Update Record On Row Deleting - Delete Record As I set Auto Generate Columns property to false so I am going to manually write the fields name that I need to appear in the way I want.
So I have to specify how I want them to appear in the normal view and edit view.
There are two buttons at the top - Update and Cancel - that are common for all the rows of the Grid View.
They are enabled only when the Grid View enters edit mode.

I'm pretty sure I need to change my Update Command of the sql Data Source that feeds my Grid View, and/or add code to my dropdown box's but I'm at a loss of how to do that.
Here is the template field of my Grid View: "UPDATE [Activity] SET [Name] = @Name, [Category] = @Category WHERE [Id] = @original_Id AND [Name] = @original_Name AND (([Category] = @original_Category) OR ([Category] IS NULL AND @original_Category IS NULL))"I've seen similar questions asked many times, but can't seem to find one that's exactly my problem.
I will be using Sql objects directly into methods to keep the example simple and straight forward. Thanks a bunch to you and the Regards Hema '''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''''''''''''''''''''''''''''''''''' reply From Brianbk [email protected] The code it update Datagridview believe me was running try this one Dim constr As String = "Data Source=localhost; Integrated Security=True" Dim sqlstr As String = "select * from Customers" Dim dt As New Data Table() Private Sub btn Load_Click(By Val sender As System. Clear() 'fill the datatable with data in the Database Dim dpt As New Sql Data Adapter(sqlstr, constr) dpt. Dispose() 'display the Table in the datagrid datagridview1. i have a problem with this code which i used it before and it really works. Now the code of Grid View rowupdating events is: Text Box txt City = (Text Box)Grid View1.(Text Box)Grid View1. Text was the updated value but the old value returns. i compared also my source code into the other which is working but there is no difference from it. Related to this problem, but much worse: I have a Grid View, which isn't bound in the ways mentioned above; I need to use a custom data source, and create the data grid cells programmatically from it. But within the Row Update event handler, everything goes null. Sorry for the wrapping in the second snippet, I just don't think there's a way to make it more eye-friendly, even if I'd raze the leading spaces. protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) please help me. i went through for loop and if loop and did all things which were of total failure i came across this right now. The code which you provided roughly a fortnight has done wonders for me. Click 'Display the Table with data in the gridview 'clear the current content of the Table dt. Find Control("txt City"); and i assume that the txt City. Old Values and New Values both have length 0, and the Text Box approach described above gives a null reference after conversion. I've posted the ASP Code, and decided to skip the actual binding code, since it works great; checked it with the debugger. NET Grid View control provides an easy way to edit and update data with the help of Command Field column type.The default Command Field arrangement is such that the Edit, Update and Cancel buttons are displayed in a column as shown below: The problem with this design is that the Grid View edit column always occupies some screen real estate.
