For the sake of the others, please update your custom sorting guide to include IsCustomSortingEnabled on the columns. I spent almost a day figuring out why the sorting didn't work anymore (It sorts once but the NewSortingState property doesn't stick). This is very frustrating and is nowhere mentioned as a requirement.

I am having the same problem as this. On the data loaded event I did the following
foreach(var column in dataGridView.Columns)
          {
              column.IsCustomSortingEnabled = true;
          }

but after performing my custom sort the NewSortingState doesn't persist? Any other ideas?
Here is my sort

private void dataGridView_Sorting(object sender, GridViewSortingEventArgs e)
    {
        //Checks if the value of the collection is null.
        if (CurrentDataTable == null)
        {
            e.Cancel = true;
            return;
        }
        if (e.OldSortingState == SortingState.None)
        {
            e.NewSortingState = SortingState.Ascending;
            SortASC(e.SortPropertyName);
        }
        else if (e.OldSortingState == SortingState.Ascending)
        {
            e.NewSortingState = SortingState.Descending;
            SortDESC(e.SortPropertyName);
        }
        else if(e.OldSortingState == SortingState.Descending)
        {
            e.NewSortingState = SortingState.None;
            ClearSort();
        }
         
        e.Cancel = true; 
    }

Hello,

 Can you post more info about your version? I've checked our demo and everything worked properly. 

Kind regards,
