'Declaration Public Overloads Sub RefreshSort( _ ByVal nodes As TreeNodesCollection, _ ByVal recursive As Boolean _ )
public void RefreshSort( TreeNodesCollection nodes, bool recursive )
The UltraTree control will automatically refresh sorted nodes when the Sort or SortComparer property is changed or when a node's Text is modified. So it is not required to explicitly call the RefreshSort method in these cases. However, it may be necessary to call RefreshSort if a customer SortComparer is being used to sort on a property other than Text. For example, if sorting is being done on the Tag property of a node, the control will not refresh the sort when a Tag is changed. Calling RefreshSort will re-sort the nodes.
