Hi Telerik Team,
I am getting a strange exception, when have a grouped gridview and refresh the datasource.
I delete in a background operation some rows and go to the database to refresh the datasource, which is binded to the grid. I get a "Specified argument was out of the range of valid values. Parameter name: index" - Exception on the setter of the datasource.
I similar problem was discriped in this thread, but I couldn't solve it for WPF.
