    I am trying to use the TreeList widget (, but with a lot of data (~2000 rows). It seems to not handle this well as it tries to load all everything at once. 

    There is a similar TreeView widget (, which allows for a configurable method called “LoadOnDemand” ( that allows the children for a node to be loaded when the parent is expanded, but I can't seem to find a similar function for the treelist widget. 

    Is there an alternative way to achieve the same functionality (loading the children on expand of their parent)?

    Hello Mike,

    The TreeList also have load-on-demand type of binding. It is demonstrated in the Binding to remote data example which populates items per level only.
