[CLOSED] Remote validation when reordering rows

[RCN]

I would like to implement a custom validation when reordering rows in a GridPanel, as shown in the following example https://examples2.ext.net/#/DragDrop...ws_Reordering/. Unfortunately i did not found a way to accomplish this task. I would like to know whether there is something close from the approach implemented in TreePanel https://examples2.ext.net/#/TreePane..._with_Service/

Hi,

Unfortunately, there is no such functionality in Ext.NET. And it's not a simple task.

I would use DragDrop events to:

1. Cancel dropping.
2. Saving what and where should be dropped.
3. Firing a request to server (I would use a DirectMethod) to validate dropping. Then in a success handler of DirectMethod make "dropping" manually if it's allowed.

Thank you Danill, please mark it as resolved

Daniil, i wonder why ext offers this functionality if i does not offer any validation as provided in TreeViewDragDrop. What is the purpose of this functionality?

Seems I am a bit confused what the functionality you are talking about. Please provide more details.

I will review your solution tomorrow.
