Showing gridview when no records present

Here is an easy solution to get a GridView to show headers when there are no records to show.

Code snippet:

DataTable dt = getResults(); //getResults would query your datasource and return a datatable

if (dt.Rows.Count > 0)
{
GridView1.DataSource = dt;
GridView1.Databind();
}
else //part that generates the Gridview with headers only
{
dt.Rows.Add(); //adds blank row to table
GridView1.DataSource = dt;
GridView1.DataBind();
GridView1.Rows[0].Visible = false; //makes blank row invisible
GridView1.Rows[0].Controls.Clear(); //removes any controls for row
}
