I am currently reviewing the latest radcontrols to decide if I'm going to upgrade from our current 2008 Q2 version of the classic version. In this progress I got the comment from our users that the they have some problems with the new interface of the filebrowsers (image manager etc)
1. the new manager is slow (minutes in stead of seconds) in showing about 1000 items (without paging) where the non ajax browser didn't have those problems.Why is the newer version so much different in loading the items? I know paging is faster but this results in the following point.
2. when paging is turned on we have to problem the that finding a specific file in the list is tedious as the default sorting is unclear on how it sorted and the users have to look at every page to see if there file is there. if sorting is turned on however it still takes longer to find a file then it used to and more actions from the user.

I am willing to customize the dialogs but I rather limit that to a minimum so there will be a lower maintenance.

Kind regards

Hi Ruud van der Veer,

Could you please try the solution provided in the following article: Setup virtual scrolling in the RadGrid embedded in RadFileExplorer?

The RadEditor's dialogs are based on the RadFileExplorer control, so you can use the FileBrowserContentProvider provided in this KB article with the dialogs as well. You need to follow the steps shown in this online demo in order to change the provider of the ImageManager dialog(the same is for other dialogs).

As an alternative, you could use the approach described in this KB article.


All the best,
