The user could customize the context menu to display the name of the selected node when right clicked on the SelectedNode by handling the MouseDown Event handler in the following way.The user have to get the right click point of the selectedNode.Then if the selectedNode is not equal to null, the a new menu item is created and added,such that the item displays the selectedNode's text name.

For displaying only the selectedNode text at a time when right clicked,the menu items must be cleared.

C#

private void treeViewAdv1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

{

if(e.Button==MouseButtons.Right)

{

//Clear the contextMenu Menuitems

this.contextMenu1.MenuItems.Clear();

this.treeViewAdv1.SelectedNode=this.treeViewAdv1.GetNodeAtPoint(new Point(e.X,e.Y));

//If the selected node is not equal to null, check for the condition

if(this.treeViewAdv1.SelectedNode!=null)

{

//Create MenuItem for the SelectedNode

MenuItem menuitem=new MenuItem(this.treeViewAdv1.SelectedNode.Text);

this.contextMenu1.MenuItems.Add(menuitem);

}

}

}

VB

Private Sub treeViewAdv1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)

If e.Button=MouseButtons.Right Then

'Clear the contextMenu Menuitems

Me.contextMenu1.MenuItems.Clear()

Me.treeViewAdv1.SelectedNode=Me.treeViewAdv1.GetNodeAtPoint(New Point(e.X,e.Y))

'If the selected node is not equal to null, check for the condition

If Not Me.treeViewAdv1.SelectedNode Is Nothing Then

'Create MenuItem for the SelectedNode

Dim menuitem As MenuItem = New MenuItem(Me.treeViewAdv1.SelectedNode.Text)

Me.contextMenu1.MenuItems.Add(menuitem)

End If

End If

End Sub
