wangxuebin Posted November 5, 2012 Author Share Posted November 5, 2012 I find the reason. With UniGui TuniTreeView,you can't use following statements for webmode: unitree.Items.BeginUpdate; ... unitree.Items.EndUpdate; for desktop app,above statements work ok,for webapp,it comes out an error, is it a little bug of UniGui?
