Currently there is not sorting method implemented in RadTreeView and the nodes are added in the order they have been added as it is shown in the Programmatic DataBinding demo.
If you want to implement some custom sorting I will recommend you to do it additionally as in the code:
SqlDataAdapter adapter =
"SELECT * FROM Employees"
DataSet links =
DataView view = links.Tables[
// To sort in ascending order:
// To sort in descending order:
// view.RowFilter = "LastName = 'Fuller'";
// view.Sort = "LastName" + " DESC";
treeView.DataSource = view;
Hope this will be helpful.
