Hello,
I've recently encountered a problem with the GridView where I get an InvalidOperationException when the grid is refreshing after changing the number of child elements on an item that already has elements and is expanded and visible within the GridView. It doesn't matter whether I'm increasing or decreasing the number of child elements. My stack trace is as follows :
Has anybody run into any similar sounding problems with the GridView ?
Edit: Upon further investigation, I've found that this problem arises in Extended selection mode, Single works just fine. For a bit of clarification, the object with the collection of child elements that's changing must be expanded in the GridView.
