title: Programmatically insert a TextBox control into GridView.FooterRow
body: <p>You can modify the columns and the <strong>ItemTemplate</strong> of columns in a <strong>GridView</strong>'s <strong>HeaderRow</strong>. But the same is not possible on the <strong>FooterRow</strong> since it's read-only.</p>
  
  <p>Is there any way that I can programmatically  add a <strong>TextBox</strong> control to a FooterRow in a <strong>GridView</strong> control?
  <br/>

  Note: I don't need databinding on the controls I add.</p>
