Ovvio, sarebbe stato il passo successivo:
codice:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
DirectCast(FindControl("TextBox1",Me), TextBox).Text = "Find it"
End Sub
Public Function FindControl(ByVal ControlName As String, ByVal CurrentControl As Control) As Control
For Each ctr As Control In CurrentControl.Controls
If ctr.Name = ControlName Then
Return ctr
Else
ctr = FindControl(ControlName, ctr)
If Not ctr Is Nothing Then
Return ctr
End If
End If
Next ctr
Return Nothing
End Function
