I am getting a strange error occurring intermittently with a xamDataGrid in WPF. The stack trace is as follows. Please advise as to what may be causing this issue. I presume it is something to with the scroll manager inside the xamDataGrid?

System.OverflowException: Negating the minimum value of a twos complement number is invalid.

The XAML is fairly straightforward databound grid:
