But according to our requirement, we will give users list box with field C.
So when they select any name on the list box C, whole hierarchy of that name should be appear.
When User select Chris from List box with filed C, total hierarchy of Chris should appear as tree view.
Right now we can only see Chris and above him in the tree view list box, but we want to see Samantha also who rolls under Chris. (like when user select Chris, we should be able to see Micheal to Samanta with chris highited in the tree view list box.) is that possible?
