private void treeViewAdv1_BeforeExpand(object sender, Syncfusion.Windows.Forms.Tools.TreeViewAdvCancelableNodeEventArgs e)
{
   Point p =this.treeViewAdv1.PointToClient(Control.MousePosition);
   TreeNodeAdv node=this.treeViewAdv1.GetNodeAtPoint(p,true);
   if(node!=null)
   {
      if(node.TextBounds.Contains(p))
      {
         e.Cancel=true;
      }
   }
}

Private Sub treeViewAdv1_BeforeExpand(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeViewAdvCancelableNodeEventArgs)
   Dim p As Point =Me.treeViewAdv1.PointToClient(Control.MousePosition)
   Dim node As TreeNodeAdv=Me.treeViewAdv1.GetNodeAtPoint(p,True)
   If Not node Is Nothing Then
      If node.TextBounds.Contains(p) Then
