Hello,

I have a Gantt that only can have two levels. I guess drag&drop is the best and easiest way to do this (Is it a better solution like editing the order value directly in the TreeList area?)

I want to implement order change in the following way. 

1. If user changes parent task order, he has to drag that parent task (A) and drop on another parent task (B). This way, task A will take task B order value (Shall task B take task A order?). If user drops parent task A on any child task, no order change will happen.
2. Drag of any child task only will be valid in the same parent. I mean, dropping child task in any parent task or in other parent child task will do nothing.

Could you send me any example of this behaviour?

Regards!
