Creating an EditCommandColu mn from code

[Ian]

Hi

I have used the following code to essentially late bind an EditCommandColu mn
to my datagrid in ASP.NET.

EditCommandColu mn ec = new EditCommandColu mn();
ec.ButtonType = ButtonColumnTyp e.PushButton;
ec.CancelText = "Cancel";
ec.EditText = "Edit";
ec.HeaderText = "Rename";
ec.UpdateText = "Update";
ec.CausesValida tion = true;
dtgResults.Colu mns.Add(ec);
ec = null;

However, the edit command that affects the grid in respect of changing
labels to textboxes does not fire even though I have set the datagrid to have
an OnUpdateCommand as follows

<asp:DataGrid id=dtgResults runat="server" AllowSorting="T rue"
OnDeleteCommand ="DataDelete "
OnCancelCommand ="DataCancel " OnEditCommand=" DataEdit"
OnUpdateCommand ="DataUpdate "
AllowPaging="Tr ue" PageSize="10" CellPadding="3"
BackColor="Whit e"
BorderWidth="1p x" AutoGenerateCol umns="False"
AllowCustomPagi ng="false"
PagerStyle-Visible="false" >

<FooterStyle CssClass="GridF ooter" />
<SelectedItemSt yle CssClass="GridI tem" />
<ItemStyle CssClass="GridI tem" />
<HeaderStyle CssClass="GridH eader" />
<AlternatingIte mStyle CssClass="GridA lternateItem" />
</asp:DataGrid>

FYI, if i use the class method of creating the EditCommandColu mn in the HTML
page, everything works fine

Any help would be appreciated
Ian
