Hello Team,

Can u pleas let me know if WPF- Diagraming component supports detection of overlapping.

If so can you please let me know the following:

1. How to detect overlapping

2. Any samples which can highlight this feature

Hi Rohan, 

 

Thanks for contacting Syncfusion Support. 

 

Requirement: Need to detect the intersection/overlap state. 

 

We have provided support to achieve your requirement in SfDiagram. We have provided support for events (DragEnter, DragOver, DragLeave) to notify the intersection/overlap state. We have explained in detail as below.  

 

Event Name	Functionality
DragEnter	This event will fire when one Node starts to intersect with other Node.
DragOver	This event will fire when one Node drag(mouse) over the other Node.
DragLeave	This event will fire when drag leaves the other Node, without dropping on another Node.
ItemDrop	This event will fire when one Node dropped on the other Node.

 

We have provided simple sample to represent these events. Please refer to the sample as below and test the sample with the above patch.

Hi,

Thanks for the demo.

Is something similar available in the classic version i.e. Syncfusion.Diagram.WPF

Also; can you tell me if we can detect this once the items are dropped and diagram is create (maybe on click of a external button)

I found one link in your forum but I cannot download the  same.
