How to close RadWindow(s) programmaticaly?

[Dean]

I need to close RadWindow(s) which are children of Application.Current.MainWindow programmatically but RadWindows present as "Telerik.Windows.Controls.InternalWindow.ChromelessWindowHelper+WindowHostWindow: Window Header" so I'm unable to cast that back to RadWindow and use Close() method. Here is what I tried:

                foreach (var w in Application.Current.Windows)
                {
                    var rw = w as RadWindow;
                    if (rw == null) continue;
                    rw.Close();
                }

                foreach (var rw in Application.Current.MainWindow.ChildrenOfType<RadWindow>())
                {                    
                    rw.Close();
                }

So, how exactly do I close RadWindow(s) which are children of Application.Current.MainWindow programmatically?

Hello Dean,

Thank you for contacting us.

The easiest way of closing all of the RadWindow instances in the current application is to use the RadWindowManager class and call its CloseAllWindows() method. More information could be found in our online help here. The next code snippet shows the described approach:

private void CloseAllRadWindows(object sender, RoutedEventArgs e)
{
    Telerik.Windows.Controls.RadWindowManager.Current.CloseAllWindows();
}

Hope this is helpful.
