LabVIEW's native tree control does not have a standard data format to save and share the tree data hierarchy, state and its values. In additional to this, the native tree control is slow to load large data sets. Considering these two major issues that users come across when using trees in labview can be eliminated by using an XML file based tree control. XML file acts as a standard format that helps to create the tree structure and also share the tree structure and values with other users. It also helps to load only subsets of large data set, thus eliminating the time to load the complete data set at once.This approach was used in one of the projects I worked and has helped to address many of these issues in the tree control effectively. Components to this control includes: XML File, XML Driver and a Tree XControl.
