    Hi,

    I have the following structure in my application:
    RadOutlookBar
        -RadOutlookBarItem
            -RadPanelBar
                -RadPanelBarItem
                    -RadTreeView (with Items)

    So, a RadOutlookBar with a RadOutlookBarItem contains a RadPanelBar with RadPanelBarItems. The RadPanelBarItem contains a RadTreeView with RadTreeViewItems.

    In the RadTreeView is also a RadContextMenu.

    When I right-clicked on a TreeViewItem of the TreeView, the ContextMenus opened-event is fired and ContextMenu.GetClickedElement<RadTreeViewItem>(); will return the right RadTreeViewItem. Then I click on a MenuItem and the ItemClick-event is fired. So far, so good.

    Well when I do this a second time, the ContextMenu.GetClickedElement<RadTreeViewItem>(); returns the RadPanelBarItem which contains the TreeView.
    As I see the RadPanelBarItem inherits from the RadTreeViewItem and the documentation says, GetClickedElement<T>() will return the top-most element of T. I think this is an incorrect behavior, because it returns two different elements and the second time the top-most element of T.
    The error occurs, when at the first time the ItemClick-event of the ContextMenu was fired, after a MenuItem was clicked.

    Got it?

    GetClickedElement<T>() should always return the last element (the innermost) of T or am I wrong?

    Thanks,
    Daniel

    Hi Daniel,

    Just to be clear - on Opened you always get the correct (top most) element but in ItemClick event you get different element, right?
    GetClickedElement should be called only in RadContextMenu Opened element. After that mouse moves and you will get different element.

    I've attached simple example using your test scenario. In Opened event you always get the correct treeviewitem.
    I don't call GetClickedElement at ItemClick event. Instead you should save the clicked element in Opened event in a local variable and clear it on Closed event.

    Let us know if you need more information.

    All the best,
