I bind a WebHierarchicalDataGrid to a List<MainItem>. "MainItem" is my custom object and has List<SubItem> member which is initially not populated.
I want to be able to expand "MainItem" rows and get subitems only when it is needeed. I don't want to prepopulte the list of subitems on initial databind.
Please provide an example.
Did you ever get a reply or get htis solved?
I am trying to do something similar and would be interested in the solution
