Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Uc1.Username = "Message text changed!"
End Sub

This is the user control code

System.EventArgs) Handles MyBase.Load

Label1.Text = Username
End Sub

End Class
----------------------------------------------------------------------------

Hi,

You need to have a member declaration for the user control at the Page as
you have already for the Label in the user control.That means a member whose
name matches the ID of the user control and type matches the code-behinc
class type of the UC.

Protected WithEvents Uc1 As uc

(Please do not cross-post)
