DispatcherFrame.Continue Property

Gets or sets a value that indicates whether this DispatcherFrame should continue.

Namespace:  System.Windows.Threading
Assembly:  WindowsBase (in WindowsBase.dll)
XMLNS for XAML: Not mapped to an xmlns.

public bool Continue { get; set; }
Members of this class are either not typically used in XAML, or cannot be used in XAML.

Property Value

Type: System.Boolean
true if the frame should continue; otherwise, false. The default value is true.

Continue is queried at the top of each dispatcher loop.

At application shutdown, all frames are request to exit.

The following example shows how to use a DispatcherFrame to achieve similar results as the Windows Forms DoEvents method.

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public void DoEvents()
{
    DispatcherFrame frame = new DispatcherFrame();
    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background,
        new DispatcherOperationCallback(ExitFrame), frame);
    Dispatcher.PushFrame(frame);
}

public object ExitFrame(object f)
{
    ((DispatcherFrame)f).Continue = false;

    return null;
}
