Hi 
   I had divided main page into two Frmeset. For header frame source will 
be Hedaer.Aspx and for second frame source will be Login.Aspx page . 
Header.aspx contain login User Name as Label control (id = lblUser) which 
will be blank on the Login page(Login.Aspx). But after validating user 
name I like to show it on Header Page from Login.Aspx page. 
   I had tried to do it with following code, but it is not working. Can 
anybody please help me to solve this problem.

Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As 
System.EventArgs) Handles btnSubmit.Click
 Dim objFrmHeader As New Header()
 Dim objLbl As New Web.UI.WebControls.Label()
 objLbl = objFrmHeader.FindControl("lblUser")
 objLbl.Text = "Welcome User "
 server.transfer("NextPage.aspx",true)
End Sub

I hope you people are understanding what I want to say. If need further 
elobration please let me know.

Thanks In Advance
Neeta
