Are you adding those two columns again in PostBack?? Because you
should. The known behavior if you don't add those columns again in
postback is that the events won't fire on those columns.

Subject: [AspNetAnyQuestionIsOk] Dynamic Datagrids
Hi, I'm trying to build an ASP.NET display page using
datagrid. This datagrid must contain: ButtonColumn &
EditCommandColumn. This is part of my code:
<asp:DataGrid id="ItemsGrid"
BorderColor="black"
BorderWidth="1"
CellPadding="3"
OnEditCommand="ItemsGrid_Edit"
OnCancelCommand="ItemsGrid_Cancel"
OnUpdateCommand="ItemsGrid_Update"
OnItemCommand="ItemsGrid_Command"
AutoGenerateColumns="false"
runat="server">
<HeaderStyle BackColor="#aaaadd">
</HeaderStyle>
<Columns>
<asp:EditCommandColumn
EditText="Edit"
CancelText="Cancel"
UpdateText="Update"
HeaderText="Edit item">
<ItemStyle Wrap="False">
</ItemStyle>
<HeaderStyle Wrap="False">
</HeaderStyle>
</asp:EditCommandColumn>
<asp:ButtonColumn
HeaderText="Delete item"
ButtonType="LinkButton"
Text="Delete"
CommandName="Delete"/>
Note that I also have defined "ItemsGrid_Edit",
"ItemsGrid_Cancel", "ItemsGrid_Update" and
"ItemsGrid_Command" in my VB code.
It all works fine. However, I want to create the
ButtonColumn & EditCommandColumn dynamically (i.e.
during run-time). So I removes those 2 pieces of ASP
code (asp:ButtonColumn & asp:EditCommandColumn) from
the aspx, and in my VB code, I add this:
Dim btnColumn As New ButtonColumn
btnColumn.ButtonType = ButtonColumnType.LinkButton
btnColumn.HeaderText = "Delete item"
btnColumn.Text = "Delete"
btnColumn.CommandName = "Delete"
Dim editColumn As New EditCommandColumn
editColumn.HeaderText = "Edit Item"
editColumn.ButtonType = ButtonColumnType.LinkButton
editColumn.UpdateText = "Update"
editColumn.CancelText = "Cancel"
editColumn.EditText = "E"
editColumn.ItemStyle.Wrap = False
ItemsGrid.Columns.Add(btnColumn)
ItemsGrid.Columns.Add(editColumn)
At first, it displays the grid correctly, however,
when I click on "Delete" or the "Edit" link button, it
never raises the event OnDeleteCommand nor
OnEditCommand!
Has anybody experienced this kind of problem as well?
Thanks a lot!
Adrian
