How to access winforms data from wpf interop?

Question

There are 2 projects in my Solution.

-WindowsFormsApplication8
-WpfControlLibrary1

I am using ElementHost from WPF Interoperability to host UserControl1 from the WpfControlLibrary1.

_________________________
Form1             - [] x |
-------------------------

  ..........
  | label1 |  // label
  ..........

// elementHost1 
// wpf control has one 
// button and nothing else
   ____________
  |            |
  |  ClickMe1  |
  |____________|

__________________________

Now,

<Canvas>
    <Button Click="btnclick">hello</Button>
</Canvas>

private void btnclick(object sender, RoutedEventArgs e)
{
    MessageBox.Show(); // this msgbox
}

I want "this msgbox" to show contents of label1.

How do I do this?
