I have a TreeView which has 5 level of child nodes, the thing is I've placed an AfterSelect event after clciking on the 4th level to generate my 5th level of child nodes.But the problem is when ever I click on the same 4th level the same thing will generate again @ the 5th level.
How can I stop it from duplicating the same nodes?
My code for the AfterSelect Event is something like this.
//Connected to database
// Populate 5th level in TreeView
foreach (DataRow dr in ordt.Rows)
TreeNode newNode = new TreeNode();
newNode.Text = dr.ToString();
