>>> Thanks for the suggestion, it worked. I have another problem now. When I click on the treeview I need to know the node that is selected, but the previous node is still selected. For example, if I have nodes A, B, C and D on my treeview A is selected and I right click on C to bring up a menu, A is still selected. Is there a way around this?
