[Solved] Group By Columns Throws Exception

[Andrew]

When I attempt to drag a column of the grid to the group by section I get the following exception that throws over and over:

System.ArgumentException: Value does not fall within the expected range.

The whole application hangs at this point. This has worked for me in the past, but I cannot figure out why I continue to get this exception now. Any ideas as to what may be causing the error?

Hello Andrew,

May you test your application with the binaries from our latest internal build ? Furthermore, you may take a look at this forum thread for a reference.

 

All the best,

Upgrading did indeed fix the issue. Thank you.
