can drag and drop and drop the leaf node to unleaf node. but how to update the field "pid" to parent's node's id?
after drag and drop, how to get current node's parent id in codebehind?

Hi @hdsoso,

You can use a TreeView's Drop DirectEvent and pass a parent node's id as an extra parameter.

it's DirectEvent not DirectListner?

[Baidaly]

Hello!

You can use either DirectMethod or DirectEvent. But you should submit required IDs.

can do with directlistner,
but how to do with direct Event? how to get destination note id with direct Event?
do you have an example?

[Daniil]

Do you mean a DirectMethod under "directlistner"? Please demonstrate how you did it and we will be happy to port your code using a DirectEvent.
