  It looks like an AfterSort event exists on some of the other platforms for the FlexGrid control. Does anything like that exist on the Xamarin FlexGrid control? I am trying to remove the row selection when sorting occurs.

  You can use the SortChanged event of the FlexGrid’s CollectionView.

  http://help.grapecity.com/componentone/NetHelp/XamarinEdition/C1.CollectionView~C1.CollectionView.C1CollectionView`1_members.html

  First add the handler:

  ((C1CollectionView<object>)grid.CollectionView).SortChanged += GettingStarted_SortChanged;
  

  Then you’ll need to remove the selection when the event fires:

          private void GettingStarted_SortChanged(object sender, EventArgs e)
          {
              grid.Select(new GridCellRange(-1, -1), false);
          }
  

  The same pattern will hold true for other CollectionView derived behaviors like filtering and grouping.

  Thanks

  Works great - thank you very much! Good to know I can handle those CollectionView events like that. That will definitely be useful.
