Hi,
I am looking for one customization with Diagram,

If User drag the Shape on any existing shape of Diagram then Dragged shape should connect with existing Shape.

So the Dragged Shape will become Destination & existing shape will bcme Origin.

Will this be possible to do with Telerik Diagram Control?

Hi,

 You can achieve this by handling the Drag event and check what items have been dragged and their new positions. Then, you can check if the dragged shape (if one) is over another shape (intersection of the bounds) and add a connection between the two shapes.

All the best,
