problem in get the requested page in main page

[prabunewindia]

i have a treeview in one frame(frame1)
and a gridview in another(frame2) both frames are in one page
when i select a node in tree i want the same page again with sorted data in
gridview.
i coded like below in my code file

protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{

Response.Redirect("DisplayFull.aspx?categoryID=" + TreeView1.SelectedNode.Value );
}
now the new page containing both tree and gridview is opening in the frame1
but i want this in full page instead of frame1
plz help me to complete my project
thanks
