Now that I have the ColumnGrouping working correctly, I've moved on to adding print support to my grid.  I have only implemented a call to PrintPreview() and my resulting print is missing the first column from my table.  The attached screen print shows both the source grid and print preview version.  Could this be related to having the first ColumnGroup marked with IsPinned=true?

Hello Pete,

Thank you for writing.

This is a known issue within the printing mechanism of RadGridView. It is already logged in our feedback portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item. This bug report is prioritized and we will introduce a fix as soon as possible.

Until then, before printing the grid you would need to unpin your pinned columns and then restore their state.

I hope this helps. Should you have further questions please do not hesitate to write back.

Thank you, the workaround works just fine.
