Ran into a problem with creating groups via XAML GroupDescriptors. I would like to set some basic groups to start with when the grid loads, and still allow the user to add new grouping using the "drag and drop into the group panel" interface. For example, load the grid grouped by county, then allow the user to choose if they would like to further group by state, city, whatever.
My problem is, when I attempt to add another group via the interface, the grouping works but each new group only has one child row even if many are available. If I then click the row header of the new grouped column, the data in the one visible row changes. So... the other rows are there somewhere, I can just see one at a time. Very odd.
If I attempt the same thing using only drag and drop with no predefined GroupDescriptors it works wonderfully.
Am I missing something, or have I run into a limitation of Grouping in the RadGridView?
Thanks for any help!
