TreeviewAdv Control ItemDrag - Enters a Recursion [Ver 3.0.1.0]

[Administrator]

Hi,

I'm using syncfusion ver 3.0.1.0 and am facing problem during drag and drop functionality in TreeviewAdv.

Sometimes, it gets into a recursive loop and emits triggers ItemDrag event handler more than once.

Here is my stack trace.

Is there some property I need to set to overcome this problem?
