Hello everyone

I have a RadGridView whose DataLoadMode is set to Asynchronous, and I'm experiencing some trouble with sorting.

In my case the grid is filled with approx 14,000 elements, that can be represented by trips made by clients. Each client has a number, and has made several trips. The columns are, among others, the client number, and the destination of the trip.

Here are the steps that reproduce my problem :
1. I first select only one client number in the standard filtering from the client number column. The display is refreshed and only the trips of the selected client are displayed (~ 4-5 elements)
2. Now I click on header of destination column, normally causing the alphabetical sorting with respect to destination. But instead of this behaviour, the grid refreshes and no elements are shown.

I have put some breakpoints, and found out that the display is not in cause, as the grid.Items is simply set with an emply collection when I click on the column header.

The surprising thing is that it always worked correctly before, when I was using synchronous data load mode.

Am I the only one experiencing trouble with this feature ?

Thank's in advance for your time

Kind regards,
Olivier
