Hi,
Thank you for your interest in Syncfusion Products.
In Syncfusion Tree View, the nodes can be moved up/down by getting the reference of the selected node and then inserting the node at correct element. The reference of the selected node can be stored in a TreeViewNode object and then the selected node can be removed with the help of its index. The removed node can then be inserted at the correct index.
We hope you have been able to get help with your technical support inquiry in this Forum. In addition to our Community Forums, we have other customized support avenues like our Direct Trac Developer Support System

Thank you for your participation in Syncfusion’s Community Forums.

Lakxman Kumar C
