Sorting results

Is there a way to extend the DataFilter so that you can select how the Filtered Results get sorted from within the editor? Something like, Sort Ascending or Descending that shows up in the drop-down list.

Thanks,
Shawn

Drag And Drop Exception in UserControl

Hello.

I have a simple wpf application based on the RadWindow which contains an UserControl. In the UserControl i have two controls: ListBox and RadScheduleView. i used very good example from Telerik WPF Demos "RadScheduleView Drag And Drop" section. It works good when everything placed into a Window (or RadWindow). But when i am using UserControl instead of window and i am trying to drag some item from the ListBox i get exception: "Value cannot be null. Parameter name: second"

Stack Trace:

   at System.Linq.Enumerable.Union[TSource](IEnumerable`1 first, IEnumerable`1 second)
   at Telerik.Windows.DragDrop.Behaviors.DragPayload.PartialTrustPayload.GetFormats(Boolean autoConvert) in c:\TB\117\WPF_Scrum\Current_HotFix\Sources\Development\Core\Controls\DragDropManager\Behaviors\Common\DragPayload.cs:line 107

GridView isBusy while pasting

Hi,

Is it possible to have the GridView set to isBusy while a pasting operation is underway? Sometimes it takes a few seconds to complete a large paste and it'd be nice to be able to have it show the user it is busy. Thanks
