nodeCreating event for diagram

Hi,

I have a problem that needs a solution.

Problem : When i drop a shape from the nodelistview control to the diagram or a container i need to do some check to see if that shape can be dropped. Based on that condition i need to allow and block the shape from getting added to diagram or container. I can do this in nodeCreating event. But unfortunatelly Mindfusion is not exposing such an event. So how can i achieve this?

I need a solution like below.

Let me know if there is any appropriate method to override.

Thanks
Kiran B

Hi,

This version raises nodeCreating also while dragging from the NodeListView:
https://mindfusion.eu/_beta/mvcdiag_js.zip

Unlike the case when drawing with mouse on the canvas, the actual node that will be added to the diagram does not exist yet, and args.getNode() returns what will be its prototype.

I hope that helps,
Stoyan
