For i As Integer = 1 To 5
    Dim wuc As Control = LoadControl("~/WebUserControl.ascx")

Hi John

is LoadControl the only way to do this?

Is there any way to strongly type the user control so you can manipulate and assess the methods and variables? What about handling events?

Add reference to the control in directive:

<%@ reference Control="~/wu.ascx" %>

This also allows to create new instance of this type and cast to it:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim w As Wu = LoadControl("~/wu.ascx")
        w.ID = "someid"
        form1.Controls.Add(w)
        AddHandler w.evt, AddressOf wu_evt
    End Sub

    Protected Sub wu_evt()
        Me.Title = "usercontrol event happened"
    End Sub

    Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim w As Wu = DirectCast(Page.FindControl("someid"), Wu)
        Me.Title = w.test
    End Sub

LoadControl method is needed for child controls of the user control to be created, as I have understood.
