OnDeleteCommand not triggering

[Tony]

I am trying to run code behind when a row is deleted but am having trouble triggering OnDeleteCommand. It doesn't even seem like it is posting back which seems to be related to ajax but am not sure what I need to add or change to get it to trigger.

VB:

Protected Sub rgMfgLot_DeleteCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) Handles rgMfgLot.DeleteCommand
       Try
           Dim lotNo As String = e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("Lot_no").ToString()
           Dim dt As Data.DataTable = DirectCast(Session("StagedRecords"), Data.DataTable)
           Dim lineRow() As Data.DataRow
           lineRow = dt.Select("Lot_no = '" & lotNo & "'")
           dt.Rows.Remove(lineRow(0))
           dt.AcceptChanges()
           Session("StagedRecords") = dt
           BindSecondaryGrid()
       Catch ex As Exception
           Response.Write("<script type=""text/javascript"">alert(" + ex.Message + ");</script")
       End Try
   End Sub

Hello,

I am attaching a sample project with Batch Cell edit mode and advanced data binding that demonstrates the proper functionality of the DeleteCommand.
Test it on your end and see what the difference in your case is.

Thanks, Maria.

 I looked over what you posted but I don't see where I am going wrong and why the delete command never gets fired. When I click on delete it never seems to actually postback at all.

 

Thanks,

Tony

Hi,

Note that the server command will be executed after SaveChanges button is clicked. Give this a try and see if it works

Thanks, Maria. That worked.

 I didn't realize I had to save the changes to get it to postback.
