Handling PreviewMouseRightButtonUp event on parent and child element separately

Hello All,

I have readonly texbox inside ListViewItem's data template. I have handled PreviewMouseRightButtonUp  event on ListViewItem to show some context menu.

As textbox by default have context menu on right mouse button click for copy paste menu. but I have handled PreviewMouseRightButtonUp  event at ListViewItem level . My textbox's default menu is not popping up.

I want to  Pop up default context menu if user right clicks in text box and my custom context menu otherwise.

How to handle this. Please provide solution.

Thanks in advance.
