FrameworkContentElement.ContextMenuClosing Event

Definition

PresentationFramework.dll

Occurs just before any context menu on the element is closed.

C#

public event System.Windows.Controls.ContextMenuEventHandler ContextMenuClosing;

Event Type

ContextMenuEventHandler

Examples

The following example implements a handler that changes the cursor over a named region DisplayArea (not shown). The comment hints at a UIElement usage, but in fact this sample would be identical if DisplayArea were a FrameworkContentElement.

C#

private void CursorTypeChanged(object sender, SelectionChangedEventArgs e)
{
    ComboBox source = e.Source as ComboBox;

    if (source != null)
    {
        ComboBoxItem selectedCursor = source.SelectedItem as ComboBoxItem;

        // Changing the cursor of the Border control 
        // by setting the Cursor property
        switch (selectedCursor.Content.ToString())
        {
            case "AppStarting":
                DisplayArea.Cursor = Cursors.AppStarting;
                break;
            case "ArrowCD":                        
                DisplayArea.Cursor = Cursors.ArrowCD;
                break;
            case "Arrow":
                DisplayArea.Cursor = Cursors.Arrow;
                break;
            case "Cross":
                DisplayArea.Cursor = Cursors.Cross;
                break;
            case "HandCursor":
                DisplayArea.Cursor = Cursors.Hand;
                break;
            case "Help":
                DisplayArea.Cursor = Cursors.Help;
                break;
            case "IBeam":
                DisplayArea.Cursor = Cursors.IBeam;
                break;
            case "No":
                DisplayArea.Cursor = Cursors.No;
                break;
            case "None":
                DisplayArea.Cursor = Cursors.None;
                break;
            case "Pen":
                DisplayArea.Cursor = Cursors.Pen;
                break;
            case "ScrollSE":
                DisplayArea.Cursor = Cursors.ScrollSE;
                break;
            case "ScrollWE":
                DisplayArea.Cursor = Cursors.ScrollWE;
                break;
            case "SizeAll":
                DisplayArea.Cursor = Cursors.SizeAll;
                break;
            case "SizeNESW":
                DisplayArea.Cursor = Cursors.SizeNESW;
                break;
            case "SizeNS":
                DisplayArea.Cursor = Cursors.SizeNS;
                break;
            case "SizeNWSE":
                DisplayArea.Cursor = Cursors.SizeNWSE;
                break;
            case "SizeWE":
                DisplayArea.Cursor = Cursors.SizeWE;
                break;
            case "UpArrow":
                DisplayArea.Cursor = Cursors.UpArrow;
                break;
            case "WaitCursor":
                DisplayArea.Cursor = Cursors.Wait;
                break;
            case "Custom":
                DisplayArea.Cursor = CustomCursor;
                break;
            default:
                break;
        }

        // If the cursor scope is set to the entire application
        // Use OverrideCursor to force the cursor for all elements
        if (!cursorScopeElementOnly)
        {
            Mouse.OverrideCursor = DisplayArea.Cursor;
        }
    }
}

Remarks

To suppress closing context menus, handlers of the event should mark it as handled.

To use this event as an EventTrigger in a style, you must reference the underlying service event identifier:

XAML

<EventTrigger RoutedEvent="ContextMenuService.ContextMenuClosing">
  <!-- storyboard here ... -->
</EventTrigger>

(This usage is required because the event implementation on FrameworkContentElement that exposes the underlying service event does not correctly map the ContextMenuClosing identifier for use in triggers).
