Call mainwindows from UserControl

Question

I have a Window(mainwindows.xaml) where there's a label.Now,i've created a UserControl(Just a basic button)..On Window_load,i'm adding the UserControl in a canvas(in mainwindow) using this :

Dim con as new myUserControl

Canvas.Children.Add(con)

Now What i want is,when i click the UserControl,the label will be hidden..How do i do this ??

I've tried creating a WPF CUSTOM CONTROL LIBRARY but don't know how to work with it ??

Go, so you also create custom controls and class libraries in C #. Then we have something in common ;-) — Héctor M.

Fixed it myself....Guess that was really easy.In usercontrol,just used this :

   Dim hm As MainWIndow = Window.GetWindow(Me)
   hm.Lbl1.Visibility=Visibility.Hidden

That's pretty horrible code really. For a start, it requires Option Strict Off. The UC shouldn't have to have such specific knowledge of the window it's on. The correct way to do that is for the UC to raise an event and for the window to handle that event and hide the Label itself.
