Try this, Assigning the Click Event to Button,
AddHandler Button1.Click, AddressOf Button1_Click
Button Click Event,
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Redirect("Message.aspx? Qoestion=" & TxtTopic.Text, False)
End Sub
This would help, I believe....
