Hello, I'm having a problem where the DataPager won't work if my RadListView has more than approximate 1,800 records. Everything is fine with small record counts returned in sql. Is something wrong with my Panels or AjaxManager? Please advise.

Hi,
I set width=100%, because I want that my editor resizes every time I do the resize of my browser window, like responsive layout. (I would set a minimum width of 600px)
But it does not work: the editor does not resize and the scrollbars appear.how can I do? thanks


to be more clear: I want to act like when it opens in full screen mode!
