Creating TemplateColumns for a grid at runtime

[Jeremy Chapman]

At run time I've added a TemplateColumn to a DataGrid.

Now I'm trying to add a Table control to the TemplateColumns's
HeaderTemplate and ItemTemplate.

In essence, I'm trying to do in code, the equilavent of this html:

<asp:TemplateColumn>

<HeaderTemplate>

<asp:Table>

<asp:TableRow>

<asp:TableCell>

</asp:TableRow>

<asp:TableRow>

<asp:TableCell>

</asp:TableRow>

<asp:Table>

</HeaderTemplate>

<ItemTemplate>
<asp:Table>

<asp:TableRow>

<asp:TableCell>

</asp:TableRow>

<asp:TableRow>

<asp:TableCell>

</asp:TableRow>

<asp:Table>

</ItemTemplate>

</asp:TemplateColumn>

I'm trying to do just that at the moment. It's a little involved. What you
do is put everything between the <HeaderTemplate> and </HeaderTemplate> tags
(not the tags) into an .ascx file, like a user control. Then
you load that file into your template column.

Trouble is, I find this method really slow. There's an alternative which is
even more complicated:

Let me know if you learn a way that performs well ...

Good luck

I'm going to try the second solution. Looks like it could be a good one.
