DropQuery and DragQuery events not fired

[Lorenzo]

Good morning
As the title say, RadDragAndDropManager dont fire the DropQuery and DragQuery events.
in XAML:

                dragDrop:RadDragAndDropManager.DropQuery="rTreeListView_DropQuery"
                dragDrop:RadDragAndDropManager.DropInfo="rTreeListView_DropInfo"
                dragDrop:RadDragAndDropManager.DragQuery="rTreeListView_DragQuery"
                dragDrop:RadDragAndDropManager.DragInfo="rTreeListView_DragInfo" 
 
and, in code behind, there is the implementation of events.
Setting a breakpoint into the events, it's never hit.
Need the DropQuery event because, in my application, there are rules that allow or not 
the drop of an element under another element;
and (as i read from help) i would like to set the QueryResult to false, cancelling drop.
The second question is:
I would like to show an icon (like denial of access)  when the DragCueItem is on an item 
on which drop operation is not allowed.

Hello Lorenzo,

I have tested how the Drag and Drop events are fired with the Q2 SP 1 version of the RadControls.

When I define them in XAML, like you have shown, they are fired fine. Along with them I set those 2 properties as well:

dragDrop:RadDragAndDropManager.AllowDrop="True"
dragDrop:RadDragAndDropManager.AllowDrag="True"

Have you defined those two properties as well?

Regarding your 2-nd question, yes, you could use an Image for the DragCue. For more information please refer to this forum post.
