How to set up an NContextMenu for a TreeNode in an NTreeView?
You should display the context menu manually since there is no such property as ContextMenu per TreeNode. You may use the following code:
[C#]
//hook to the tree-view's MouseUp notification
this.nTreeView1.MouseUp += new MouseEventHandler(OnTreeView_MouseUp);
//inside the body of the handler method put the following code
private void OnTreeView_MouseUp(object sender, MouseEventArgs e)
{
if(e.Button == MouseButtons.Right)
{
if(myNode.Bounds.Contains(e.X, e.Y))
{
//the Show method of the context menu requires screen coordinates
Point screen = Control.MousePosition;
myContextMenu.Show(screen);
}
}
}
[VB.NET]
'hook to the tree-view's MouseUp notification
Me.nTreeView1.MouseUp += New MouseEventHandler(OnTreeView_MouseUp)
'inside the body of the handler method put the following code
Private Sub OnTreeView_MouseUp(sender As Object, e As MouseEventArgs)
If e.Button = MouseButtons.Right Then
If myNode.Bounds.Contains(e.X, e.Y) Then
'the Show method of the context menu requires screen coordinates
Dim screen As Point = Control.MousePosition
myContextMenu.Show(screen)
End If
End If
End Sub
