  I’m using C1FlexGrid and I’ve encountered a problem with scrolling.

  I have a grid with one row in the ColumnFooters panel. When I scroll down to the last item using the mouse wheel, everything is OK and the last item is visible.

  

  But when I scroll down by clicking the buttons on the scroll bar, then the last item remains invisible, sort of hidden behind the footer row, even though the scroll bar has reached the maximum.

  

  I have reproduced the issue in a sample app using C1.WPF.FlexGrid.4.5.2.dll, version 4.5.20211.739 as well as 4.5.20212.747. I am in the process of upgrading from an older version of C1FlexGrid, specifically 4.0.20123.282, where I did not see this kind of behavior.

  Is this a bug in C1FlexGrid or am I doing something wrong?

  Hi,

  We are happy to inform you that this issue has been fixed with the latest build 2021v3.
  
  So, we would request you to upgrade to the latest build using ComponentOne control panel. Just in case if you don’t have ComponentOne Control Panel, you can download it from https://www.grapecity.com/componentone/download.
