Unexpected items selection on Drag and Drop on Grid

[Mihai]

Hi,

 I'm using telerik version 2014.3.1202.1050 with Silverlight 5.

I have a drag and drop functionality implemented to drag one or more items from a RadGridView to a RadScheduleView.

The scenario I'm having issues with is the following:

- I select one item on the grid.

- Click on another item on the grid and drag it to the schedule view but I don't drop it on the schedule view.

- Move the mouse back on the grid and drop it back there.

 Now when I move the mouse on the grid up and down without having clicked anything or having the Shift key pressed all the items which are hovered are selected.

 

Any ideas why?

 

In the meanwhile I added a behaviour which cancels the SelectionChanged event when this scenario occurs, but this is a workaround.

 

Thanks and regards,

Mihai

Hi Mihai,

Actually, this is a known limitation in Silverlight. Check out the "Corrupted Extended Selection" article for a reference.

Hi Maya,

 Thanks for your reply. I was not aware of this limitation. Thanks for pointing out the article.
