How do you close open dialogs in a silverlight app?

Question

I have an automatic-lock functionality in my Silverlight app that needs to lock the screen after a certain period. The problem is that open dialogs remains open even if the app is locked.

How do I close these dialogs programatically?

you should add this like :

 dialog.DialogResult = false;
 dialog.Close();

the particular problem here is not the actual closing of the dialog, but to find the reference to the dialog. I need to first find it in the VisualTree from that point closing it works exactly like you described... – gyurisc Jun 29 '13 at 07:54

I use the following code snippet to close open dialogs in my silverlight app.

    UIElement ui = App.Current.RootVisual;
    foreach (var popup in VisualTreeHelper.GetOpenPopups())
    {
      if (popup != null)
      {
        System.Windows.Controls.ChildWindow dialog = popup.Child as System.Windows.Controls.ChildWindow;

        if (dialog != null)
        {
          dialog.DialogResult = false;
          dialog.Close();
        }
      }
    }

This only works in Silverlight 4 or newer.

Set a `DialogResult` and call `Close` can mark your App as disabled (If close animation). Just use one to prevent this... — Tonio, Jun 14 '13 at 13:53
