Hi,
I've included a right click function on a treeview1 to delete a gandchild node.
But the thing is after deleting I want the treeview1 to refresh so that the user can't see the deleted granchild node.

I tried treeview.Refresh();but it did'n work.I hope someone can offer me some help or advice.
Thanks in advance.
