Use controls from other forms

Question

Hi there,

I'm in needing of help of using controls from another form. Here is what I want to use it in:

if (form2.checkbox1.IsChecked)

{

messagebox.Show("Form2 Checkbox1 is selected!");

}

But it doesn't show the controls on form2 when I type:

 private void Window_Loaded(object sender, RoutedEventArgs e)

        {

         Form2.

        }

Any help will be greatly appreciated! :)
