HandledBy (Inherited from Intersoft.Client.Framework.ISRoutedEventArgs)	Gets or sets the source object that handles this event.
IsHandledByPrimitive (Inherited from Intersoft.Client.Framework.ISRoutedEventArgs)	Determines whether this event is handled internally by control infrastructure.
OriginalSource (Inherited from Intersoft.Client.Framework.ISRoutedEventArgs)	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.
RoutedEvent (Inherited from Intersoft.Client.Framework.ISRoutedEventArgs)	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.

The following example shows how to prevent a window from being closed by handling its Closing event and set the Handled property of the event data to true.

C#

public partial class HomeWindow : UXWindow
{
    public HomeWindow()
    {
        InitializeComponent();
        this.Closing += new Intersoft.Client.Framework.WindowEventHandler(HomeWindow_Closing);
    }

    void HomeWindow_Closing(object sender, Intersoft.Client.Framework.WindowEventArgs e)
    {
        if (DocumentNotSaved)
        {
            MessageBox.Show("Your document has not been saved. Close aborted");

            // When the Handled is set to true, the window will cancel the Close command.
            e.Handled = true;
        }
    }
}
