setting the value of a checkbox programmatically in c# (wpf)

Question

I\'m working on a small wpf project using c#. I have 2 windows. When I go from one window to the next, i need to have some items preselected on the 2nd window. I have a check

Answer 1

Using this:

        Window2 w2 = new Window2();

        //This doesn't work             
        w2.Checked = true;

You're setting the Checked property of the window not the control. It should be somehting like this:

        Window2 w2 = new Window2();        
        w2.MyCheckBox.IsChecked = true;

Answer 2

I'd say that you should move towards pushing the view model into the view via IoC or some other fashion. Tie the value to a property and let the framework make your life easier via binding, instead of having to hard code values all over the place.

Answer 3

You can use the IsChecked property.

I hope this helps. Damian
