Instaed of a place holder put a frame and change the src attributes of the frame.

    if (TreeView.SelectedNode.Text =="Data Entry Screen")          {                   frame1.Attributes["src"] = "ReportCriteria.aspx";           }

but you I thinks code above !1
It will run
but I have a error

[Shashi Sadasivan]

the error lies in the declaration of default2.aspx

Have you changed the inheriting class of it?
