Bug: Can't "unclick"/release a scrollbar (Only tested with the vertical scroll bar)
My Telerik.windows.controls.gridview version is 2010.2.812.1040
Cause
1. Have a grid view with enough items such that it creates a scroll bar
2. Click and hold the scroll bar
3. Whilst you are holding the scroll bar, some event should block access to the grid. (e.g. I have a busy indicator around the grid and the IsBusy becomes true the false)
You are now unable to release the scroll bar, and it is in a permanently "clicked" state

Hi Alex,
Can you give us some more details about point 3 - how exactly are you setting IsBusy="True" upon scrolling the grid ? It will be best if you send us a sample application (via support ticket) where we will be able to debug and investigate the problem. Thank you.

I am setting it off with a DataLoading event from my client side data source (That links to RIA) and it is bound to the DataSource.IsBusy
(A similar issue also occurs when moving a radwindow, if you loose focus whilst holding down and moving the window, you can't let go of it)

Hi Alex,

Unfortunately, we are unable to reproduce your case so is it possible to send us a sample application that demonstrate it ? In this way we will be able debug the problem and to provide you with appropriate solution. To do this you need to open a separate support ticket and to attach your application there.

Hi Alex,
I think I know the problem you are talking about.
It is easy to replicate with a RadGridView which is used with VirtualQueryableCollectionView, When you scroll UP or DOWN the grid, and you have Scroll back pushed with mouse button, the problem appears when VirtualCollectionView starts reading data for the scrolled region and Busy indicator kicks in.
Try the ScrollMode= Deferred instead of Realtime as work around to this problem
Hope it helps
