I’ve made a new ReportDataSource that needs to return many distinct values; some of which happen to be datasets. I would like to know how to group all these values under a single heading (key) in the report designer tree. I put all my values into a dataset, but nested datasets don’t seem to show their own columns in the tree of keys. You guys have accomplished this with nested queries (you can see the columns of the child dataset by expanding their tree). I’ve considered them being separate keys, but this would clog up the tree in the report designer unnecessarily. What sort of structure do I need to produce from my ReportDatasource to have multiple levels of keys available to the user?
edit: I should add that the dataset of all my values is just a single row where each value has its own column. This was my attempt at grouping the values under one heading.
