    I am using the TreeList to load a tree from a JSON Service. I have the requirement that on double clicking a node not only one level should be expanded but all remaining levels. Is there any way to do this?
    One part that I find tricky is to find out which rows belong to a certain parent row. Another thing is that the expand method of the TreeGrid does not return a Promise which makes it difficult to know when a level has been loaded.

    Hello Michael,


    You can use expand method to expand a row and recursively expand all its children. There isn't built-in API for this.


    You can check whether a level is loaded by inspecting the loaded state of the TreeListModel.
