If set to empty string the method gets the next max number + 1 from the data. if parendid is null the node is added as root. If the parentid is valid id of existing row the data is added as child of the that row. Data is a data to be inserted.| | ||

| * When we initialize the grid and the data is read, the datatype is automatically set to local. This is required because treegrid supports autoloading tree nodes. This means that, for speed or efficiency, you can load the data only for the root level first and load the data for a particular child node only when the operator clicks to expand that node. The grid will determine that there is no data and try to load the node from the server, but in this case the data that is sent to the server has to have additional parameters. Setting datatype to local permits intervening before the request is made to build the request correctly.
