//The event is raised when pressed key is released.
this.treeViewAdv1.KeyUp += new KeyEventHandler(treeViewAdv1_KeyUp);
void treeViewAdv1_KeyUp(object sender, KeyEventArgs e)
{
    if(e.KeyValue == 93)
    {
       //Specifies the location where Context menu needs to be shown. 
       int x = treeViewAdv1.SelectedNode.TextBounds.X;
       int y = treeViewAdv1.SelectedNode.Bounds.Y + treeViewAdv1.SelectedNode.Bounds.Height;
       Point point = new Point(x, y);
       Point ContextPoint = treeViewAdv1.PointToScreen(point);
       //Shows the ContextMenuStripEx.
       this.contextMenuStripEx1.Show((ContextPoint));
    }
}

'The event is raised when pressed key is released.
AddHandler treeViewAdv1.KeyUp, AddressOf treeViewAdv1_KeyUp
Private Sub treeViewAdv1_KeyUp(ByVal sender As Object, ByVal e As KeyEventArgs)
    If e.KeyValue = 93 Then
       'Specifies location where Context menu needs to be shown.
