After upgrading Infragistics 16.1 to 18.1, ViewState is getting corrupted


I just upgraded the infragistics dlls from 16.1 to 18.1 and started getting below error:

Sys.WebForms.PageRequestManagerServerErrorException: Infragistics.Web.UI.GridControls.ColumnResizeSettings ViewState is corrupted.

If I disable viewstate for particular page then it works fine. Is there any common solution without disabling ViewState?

    It isn't expected that upgrading would cause view state to be corrupted.  To look into this we need to be able to reproduce the issue locally.  Please provide us with a sample that demonstrates the issue.  If you aren't able to create a sample that demonstrates the issue, please provide at least the markup for the grid and any logic in the code behind that sets properties on the grid so that we can understand what is being done during the page life cycle.

    Let me know if you have any questions with this matter.
