Is it possible to hide one group in a RadGrid?
===

Quick background of the grid as it exists:

The requirements I've been given require the grid to be grouped into categories, with inserting and editing to be done by clicking a "dummy row" (as I've dubbed it) as the first item in the grid, and editing it's properties in some text boxes at the bottom of the page. Basically, I get the DataTable, then before I set the DataSource (in NeedDataSource), I add a row to the DataTable with information that amounts to "Click here to insert a new row."

Editing the data this way seems somewhat silly to me, but this is how it must be. My question is, can I hide one group? The grouping is done using a GroupByExpression with GroupByFields and SelectFields.
