Problem with right click in treeview(URGENT )

[sugee]

hi,
I have a treeview when rightclicked a context menu should appear. but first time wen i right click the context menu of that node(ie, add,delete) appears whereas when i right click another node the context menu of the previously selected node appears.ie, context menu with add, delete appears instead of add,delete and edit.can anyone help in this issue. Here is my code.
if(e.Button==Mo useButtons.Righ t)
{
treeView1.Selec tedNode = this.treeView1. GetNodeAt(e.X, e.Y);
//MessageBox.Show (this.treeView1 .SelectedNode.T ext);
Point clickPoint = new Point( e.X,e.Y );
TreeNode clickNode = treeView1.GetNo deAt( clickPoint );
if ( clickNode == null ) return;
else
{
treeView1.Selec tedNode = clickNode;
// Convert from Tree coordinates to Screen coordinates
Point screenPoint = treeView1.Point ToScreen( clickPoint );

// Convert from Screen coordinates to Form coordinates
Point formPoint = PointToClient( screenPoint );

if(treeView1.Se lectedNode.Text =="collection ")
{
treeView1.Conte xtMenu= popUpMenu;
treeView1.Conte xtMenu.Show(thi s,formPoint);
}
else if(treeView1.Se lectedNode.Text =="TestCase")
{
treeView1.Conte xtMenu=TreeMenu ;
treeView1.Conte xtMenu.Show(thi s,formPoint);
}
}
}
