DragVisual position relative to cursor

[Vincent]

Hi,

I use an Image that is shown when dragging:

args.DragVisual = new ContentControl { Content = MyImage, Width = 25, Height = 25 };

This image always shows up at a certain position relative to the cursor.
Can I influence this position? I tried DragVisualOffset but - maybe I used it incorrect -
that didn't result in a change of position.
Thanks in advance,
Vincent

Hello Vincent,

You can use the DragVisualOffset property in combination with the RelativeStartPoint properties of the DragInitializeEventArgs to achieve the desired effect. 

Hope this helps!

Hello Nik,

the property RelativeStartPoint has an internal setter which I therefore can't change in the OnDragInitialize eventhandler which is passed to the DragDropManager:

DragDropManager.AddDragInitializeHandler(control, OnDragInitialize, true);

Should I change this property (together with DragVisualOffset) somewhere else instead of in this handler? 

Kind regards,
Vincent

Hello Vincent,

The RelativeStartPoint property gives you the relative coordinates of the mouse pointer when starting a drag operation. You cannot set it. You can use it to calculate your own offset, and set it to the DragVisualOffset propery.

Hope this helps!

Hi,

the reason it didn't work in my case was that I probably used absolute X,Y-coordinates instead of calculated relative to RelativeStartPoint. I found the right piece of code in this topic:
