Failed to sort by column header of nonexistent column

Yes, I confirm that this is a bug inside iGrid. It appeared in the iGrid.NET 6.0, a big major update we released recently.

We'll fix it in a day or two. I'll post in this thread when it is done.

The problem has been fixed. The updated demo on the website contains a new build of iGrid.NET with the bug fix.

To try it, uninstall the demo you have, re-download the archive with the demo from our website, and install it again.

Post a message here to let us know whether the problem has been really fixed.

Thanks, error fixed.
