We have a grid with its ItemsSource bound to a QCV (and an EF query as source). There has to be a sorted column so that Paging works properly. However, I can also completely remove a sort which means paging is no longer working. How can I prevent the user from "un-sorting" a column? What I would like to have is instead of a threestate sorting (asc, desc, unsorted) only a twostate sorting (asc, desc). Any idea?

Hi Neils,

As to your second question, you can modify the way sorting is applied Ascending or Descending with a code similar to: 
void clubsGrid_Sorting(object sender, Telerik.Windows.Controls.GridViewSortingEventArgs e)
{
    if (e.NewSortingState == Telerik.Windows.Controls.SortingState.None)
    {
        if (e.OldSortingState == Telerik.Windows.Controls.SortingState.Ascending)
            e.NewSortingState = Telerik.Windows.Controls.SortingState.Descending;
        else
            e.NewSortingState = Telerik.Windows.Controls.SortingState.Ascending;
    }
}

I hope this helps.
