Hello Laurent,

I have prepared an example project that illustrates a basic drag and drop scenario between a RadPropertyGrid and a ListBox. Would you please shed some more light on your requirements, especially on RadRichTextBox's role, in case that you have met any obstacles while adapting the approach from my project to your needs? I am attaching the example for your reference.

Best wishes,

Thank you very much Ivan,

I
see the principle well now.

Unfortunately, I have just tested your application and this one does not function,

function
 
e.GetElement<PropertyGridField>(Mouse.GetPosition(this)) 

always
return null

I have just remade some tests with your application, apparently, that functions but it takes PropertyGridField located at the top of that selected.

Therefore, that operation not if I Drag "Age", but if I Drag FirstName, it find Age

Moreover, that functions only if I am in full screen.

I found the solution, it seems to me.

In
private void OnDragQuery(object sender, DragDropQueryEventArgs e) 

I
have replace

PropertyGridField field = e.GetElement<PropertyGridField>(Mouse.GetPosition(grille)); 

by


PropertyGridField field = e.Options.Source as PropertyGridField;

With the new DragDropManager (instead of RadDragAndDropManager), how to get the PropertyGridField when mouse is dragging over it?
(The DragEventArgs is not the same as DragDropQueryEventArgs.  It doesn't have GetElement().

Hello,

You can use the e.OriginalSource property in combination with the ParentOfType extension method to get the target PropertyGridField.
var field = e.OriginalSource as PropertyGridField ?? (e.OriginalSource as FrameworkElement).ParentOfType<PropertyGridField>();

Hope this helps. 


Regards,
Nik
