Hierarchical databinding against ultrawintree
posted

I have a bindinglist containing three columns nodeId, NodeName and parentNodeId

When I set the datasource to that bindinglist how do I get the ultrawintree to handle the hierarchy so that each node is connected to the correct parent?

    Hi,

    The tree binds to the structure you give it. If you give the tree a flat BindingList, then it will only show a flat list.

    If you want to create a hierarchy, you have to give the tree a hierarchical data source, or else manually populate the tree without data binding.

    So one way to do this would be to use a DataSet instead of a BindingList. The DataSet support hierarchical data via Relationships.

    Another option would be for the items in your BindingList to have a property that returns the child BindingList<T> that contains the child items.
