Retrieve the clicked item when the RadContextMenu is opened.

Solution

You can derive from the RadContextMenu class and add an additional dependency property.

Deriving from the RadContextMenu class and adding an additional dependency property

C#

	public class ExtendedContextMenu : RadContextMenu
	{
	    public static readonly DependencyProperty ClickedItemProperty =
	        DependencyProperty.Register("ClickedItem", typeof(FrameworkElement), typeof(ExtendedContextMenu), new PropertyMetadata(null));

	    public FrameworkElement ClickedItem
	    {
	        get { return (FrameworkElement)GetValue(ClickedItemProperty); }
	        set { SetValue(ClickedItemProperty, value); }
	    }
	}

VB.NET

	Public Class ExtendedContextMenu
	    Inherits RadContextMenu

	    Public Shared ReadOnly ClickedItemProperty As DependencyProperty = DependencyProperty.Register("ClickedItem", GetType(FrameworkElement), GetType(ExtendedContextMenu), New PropertyMetadata(Nothing))

	    Public Property ClickedItem As FrameworkElement
	        Get
	            Return CType(GetValue(ClickedItemProperty), FrameworkElement)
	        End Get
	        Set(ByVal value As FrameworkElement)
	            SetValue(ClickedItemProperty, value)
	        End Set
	    End Property
	End Class

To assign a value to the dependency property, override the OnOpened method and call the GetClickedElement method. This method will allow you to retrieve the first element of the given type at the click point coordinates.

In the following example, the custom RadContextMenu is used in the RadTreeListView control and a reference to the clicked TreeListViewRow instance is retrieved in the OnOpened method.

C#

	public class ExtendedContextMenu : RadContextMenu
	{
	    public static readonly DependencyProperty ClickedItemProperty =
	        DependencyProperty.Register("ClickedItem", typeof(FrameworkElement), typeof(ExtendedContextMenu), new PropertyMetadata(null));
	
	    public FrameworkElement ClickedItem
	    {
	        get { return (FrameworkElement)GetValue(ClickedItemProperty); }
	        set { SetValue(ClickedItemProperty, value); }
	    }
	
	    protected override void OnOpened(RadRoutedEventArgs e)
	    {
	        base.OnOpened(e);
	
	        this.ClickedItem = null;
	        this.ClickedItem = this.GetClickedElement<TreeListViewRow>();
	    }
	}

VB.NET

	Public Class ExtendedContextMenu
	    Inherits RadContextMenu

	    Public Shared ReadOnly ClickedItemProperty As DependencyProperty = DependencyProperty.Register("ClickedItem", GetType(FrameworkElement), GetType(ExtendedContextMenu), New PropertyMetadata(Nothing))

	    Public Property ClickedItem As FrameworkElement
	        Get
	            Return CType(GetValue(ClickedItemProperty), FrameworkElement)
	        End Get
	        Set(ByVal value As FrameworkElement)
	            SetValue(ClickedItemProperty, value)
	        End Set
	    End Property

	    Protected Overrides Sub OnOpened(ByVal e As RadRoutedEventArgs)
	        MyBase.OnOpened(e)
	        Me.ClickedItem = Nothing
	        Me.ClickedItem = Me.GetClickedElement(Of TreeListViewRow)()
	    End Sub
	End Class
