Sort Hyperlinks Not Showing Up (ASP.NET 2.0)

[Don]

In my code I'm dynamically creating a GridView control and binding it to a
DataView object that I create form a DataSet that I get from a web service
call. It seems that no matter what I do I can not get the sort hyperlinks in
the header row to show up. I've set AllowSorting to true and various other
things but no matter what I do I can't get them to show up. Does sorting only
work with the new SqlDataSource and related objects in ASP.NET 2.0 and not
data sources like the DataView object.

Thanks

Just to help clarify here's a snippet from the problem code:

protected override void Render(HtmlTextWriter writer)
{
DataView dv = new DataView(_ds.Tables[0]);
_gv = new GridView();
_gv.AllowSorting = true;
_gv.DataSource = dv;
_gv.DataBind();
_gv.RenderControl(writer);
}

When I use this code no matter what properties I seem to set I can not get
the sort hyperlinks in the header row to show up. If I declaratively create a
GridView control it works fine. It's only if I dynamically create the control
as I've done above that I have the problem.

Ideas?
