SelectedItem is null after cell edit and auto sort

Hi,
I have a RadGridView bind to a datatable and sort by Name column. My problem is after I modify the Name column, the RadGridView performs a 'auto sort' and the current selected row is deselected and the SelectedItem is Nothing.

How can I preserve the selected row after the 'auto sort'?

Thanks,
Chris

Hi all
in the current q1 sp1, RadPanes are inside the docking if docking has a smaller width. this was not a problem in the previous q1 release. please use the following code to generate the error. I am also attaching the screen shot.

schedule view not compatible with windows phone 7.1

I am building an application in Windows Phone 7.1, which uses Silverlight 4 controls.
Now I need to use RADScheduleView control of telerik, which needs Advanced version of Silverlight (5.5).
I have Installed Silverlight 5.5 but not able to add its reference in my Windows Phone express edition 7.1 OS

Map is stalling causing update glitches.

I am using the Telerik map, I am driving the map with custom controls, that I have on a timer update function
When I move the map struggles to catch up & becomes quite jerky. I need to drive the map this way I don't have a choice in this. Using the Telerik controls to drive it is not an option unfortunately.

From what I can tell it looks like the map or the provider is blocking the UI thread which causes the stall.
This bug is more apparent in high resolutions.

Below is the code I am using to generate the error (I know the code isn't perfect but it highlights the bug)

turn these defines on to change timer methods (1 at a time please) or turn them both off to use the onIdle event

#define DISPACTTIMER
#define THREADTIMER

Escape does not work properly for Rad TreeView

We have used Rad TreeViewControl in our WPF application. When we press 'Escape' key, sometimes it does not reset the value and retains the value entered.

Docking problem on Citrix

Hi, one of our customers are getting exceptions when they are docking toolwindows. The exception occures when dragging a window to one of the arrows in the "diamond". They are running the application on a 2003 windows server with Citrix. I'm guessing they are running into a Citrix or network issue as this behavior is not reproducable in test environments. The exception beeing thrown is:
