Select an Entity

[Abdallah-BIM]

I have a desktop application that is using two 3DDrawingControl controls each an old version and a newer version to compare the two of them

I'm showing the data for the changed elements on a new WPF form to show the change data in a data grid I want to wire the data grid selection changed event to select the specified element on the drawing control

but that isn't working as expected

here's a picture showing the two drawing controls and the data grid form
