drag drop TreeView

[Sandeep]

Hi,
I am working with the drag drop functinality fo the TreeView.
After dropping the node I want to check if the node I am dropping is right/wrong. If it is right not then no problem, but if it is wrong node then I want to cancel the process means I wont allow to drop the node. Is there any way I can handle this functionality?

Thanks,
Sandeep

Hi Sandeep,

I have attached a sample in which i have checked the condition to drop the child nodes of "MailBox" alone. "Personal Folder" child nodes cannot be dropped into MailBox.

In the ClientSideOnNodeDrop event, you can check your condition (as per your requirement specify the condition) and if it is satisfied, True will be returned and the node will be dropped else the function will be cancelled.

Is there a way to do this on the server side?

Hi Kathy,

Thank you for your interest in Syncfusion products.

Server side condition checking during node drop in TreeView.

I am able to see the issue of that you have mentioned here. But we do not have any server side event to check the condition during node drop and we have only TreeView_NodeDropped event which will be fired after the node is dropped in to the treeview. So I regret to let you know that it is not possible to check the condition in server side during the node drop. Sorry for the inconvenience.
