Hi Telerik! Today I've been learning about grouping (in tables, to be specific). Could you please add to your documentation that a table must first have the Detail group before you can add any other groups? I spent an unfortunate amount of time thinking that a parent row grouping could be added *before* the Detail grouping. Bummer, dude. Sad panda.
So yeah, I like to think of myself as a little mine sweeper. If I find a mine, I like to plant a little flag so that others don't have to walk over the mine. Anyhoo... yeah, Detail first, then other table groups.

Hi Greg,
There is no prerequisite to have a detail group in the Table/CrossTab/List report item. The easiest way to verify that is to drag & drop the CrossTab item onto the design surface, open the Group explorer and verify that it does not have a detail group. More structured information about the Table item, Detail and Group data is available in the Basic concepts help article.
To illustrate it in a more straight-forward and probably easy to grasp way, depending on the grouping criteria, we have:

To illustrate it in a more straight-forward and probably easy to grasp way, depending on the grouping criteria, we have:
- dynamic groups - have any Grouping expression, ex. group1.Grouping.Add(new Grouping("=Fields.Country")). For the dynamic groups, the corresponding row/column will repeat for every record of the grouped data.
- static groups - no grouping criteria at all. For the static groups the corresponding row/column is rendered only once.
- detail groups -have a single empty grouping, ex. group1.Grouping.Add(new Grouping()). Usually you have only one row -or- column detail group. For a detail group the corresponding row/column is repeated for every row of the Table's data source. You may think of the detail TableGroup as the Report's Detail section.
