With TelerikRadTreeView , I have various types of items visible in the tree.

The presentation for all tree items is always same and hence I am using single template for displaying all the items.
The difference for these items is in their context menus. For each item, depending on the type different context menus are available.

I am tring to build these context menu dynamically.  To achieve this I am doing following things -

1. RadContextMenu object is created and binded to the treeView.
2. For TreeView control , MouseRightButtonDown and MouseRightButtonUp event is handled.
    MouseRightButtonDown only contains statement e.Handled = true.
    MouseRightButtonUp , clears the items from the context menu , add few items and then IsOpen property of contextmenu is set to true.

To show the context menu properly depending on the item type (binded) I need to know for which radtreeItem mouserightbuttonup event triggered.

Is there any possiblitiy, that I can get the correct radtreeviewItem in mouserightbuttonup event ?
How one can use VisualTreeHelperExtensions functions which gives me correct RadTreeViewItem.

Hello Niranjan,

Usually , when you define a RadContextMenu within your RadTreeView, the item under your mouse is getting selected on mouse right button click. Could you try to use the  treeView.SelectedContainer in your MouseRightButtonUp event ?
On the other hand, you could examine the following demo showing a good approach when different types of context menus are needed. Feel free to ask if you need further assistance.
