That's not true. Just try add "console.info('dnd');" to treegrid dnd demo's "onLoadSuccess" function,
http://www.jeasyui.com/extension/downloads/treegrid-dnd.zipYou will find it triggered every time when leaf is droped,
But if you add the same code to datagrid dnd , it will not work as the same way treegrid do.
http://www.jeasyui.com/extension/downloads/datagrid-dnd.zipIn my app, I need to change the display of data after data loaded (can't use formatter, because I need to add params), so I put some code into onLoadSuccess to do the work. treegrid-dnd triggered "onLoadSuccess" every time when data is droped, but datagird did't do it , I don't konw what to do now , I really need it works.
