GridView - Show headers on empty data source

Question

In C# how do I still show the headers of a gridview, even with the data source is empty.

I am not auto generating the columns as they are all predefined.

Answer 1

ASP.Net 4.0 added the boolean ShowHeaderWhenEmpty property.

Note: the headers will not appear unless DataBind() is called with something other than null.

GridView1.DataSource = New List(Of String)
GridView1.DataBind()
