Hello,
I'm doing a small project and just upgraded to the latest version of WPF telerik control. In my project I had some drag and drop between grid and listbox. Pretty much the same as the one in the demo (http://demos.telerik.com/silverlight/#DragAndDrop/TreeToGrid) this one but the wpf version. I used to be able to drag my item from the list without any problem but now it just doesn't work. The new WPF demo does not seem to work too.
Any ideas to what is wrong?
thank you very much

Hi Francois,
Please, try setting this attached property to True on these ListBoxItem instances that you are going to drag: Telerik.Windows.DragDrop.DragDropManager.AllowCapturedDrag. The easiest way to achieve this is to use a style like this:

Hi Ivan,
thank you for you quick answer, but is this suppose to work for the WPF control?
Telerik.Windows.DragDrop.DragDropManager.AllowCapturedDrag does not exists in the assembly that I have. Maybe I have the wrong version but the online help doesn't state a properties by that name either.

Hello Francois,
Tsvyatko

DragDropManager.AllowCapturedDrag is relatively new property available after version 2011.2.718. It is used in scenarios in which we need to perform drag drop operations on control that captures the mouse and interferes with drag drop framework execution (as in WPF listbox). We are currently updating our help articles as well in order to include this information as well.

Hi Ivan,
I tried to upgrade to the latest version available and I still can't see that propertie. I downloaded 2011.2.0725 for .NET 3.5
is this property only available while using .NET 4.0 ? My project can only use .NET 3.5

Hello Francois,
It is available in 2011.2.725 for .NET 3.5. I am attaching a screenshot that provides some more extensive information of its location.

i have basically the same problem (drag doesn't work from list box in WPF). I have downloaded the hotfix 2011.2.0808 for WPF for .net 4.0. However the AllowCaptureDrag property is not available as you can see in the screenprint. Am i doeing something wrong here or has the new property disappeared?
TIA

Hi Ronald,
the property can be found under Telerik.Windows.DragDrop.DragDropManager
you are currently looking at Telerik.Window.Controls.DragDrop.RadDragAndDropManager
I made the same mistake at first ;)
