[RESOLVED] Plzzzzzzz Help Meeeeeeeeeeee

this code just call parent node of treeVIew how we call Child Node
if (treeView1.Nodes[1].IsSelected == true)
{
frmPersonalNo personal = new frmPersonalNo();
personal.Show();
}

I believe you can check for

if(treeView1.Nodes[1].Nodes[4].Selected==true}

Since Nodes is a NodesCollection object.
