How do I get Gridview to render THEAD?

Question

How do I get the GridView control to render the tags? I know .UseAccessibleHeaders makes it p

I use the following code to do this:

The if statements I added are important.

Otherwise (depending on how you render your grid) you'll throw exceptions like:

The table must contain row sections in order of header, body and then footer.

protected override void OnPreRender(EventArgs e)
{
    if ( (this.ShowHeader == true && this.Rows.Count > 0)
      || (this.ShowHeaderWhenEmpty == true))
    {
        //Force GridView to use  instead of  - 11/03/2013 - MCR.
        this.HeaderRow.TableSection = TableRowSection.TableHeader;
    }
    if (this.ShowFooter == true && this.Rows.Count > 0)
    {
        //Force GridView to use  instead of  - 11/03/2013 - MCR.
        this.FooterRow.TableSection = TableRowSection.TableFooter;
    }
    base.OnPreRender(e);
}

The this object is my GridView.

I actually overrode the Asp.net GridView to make my own custom control, but you could paste this into your aspx.cs page and reference the GridView by name instead of using the custom-gridview approach.

FYI: I haven't tested the footer logic, but I do know this works for Headers.
