Finally chased this one down but it appears that in the 14.1.20141.2059 release (and previously to this as I have been hitting this for some time now but not been able to research further) that the FixedRows Collection isn't properly being cleared behind the seen and after applying a new DataSource it throws an internal index error when it attempts to fix a row that no longer exists. Previously (I have no clue when the UltraGrid stopped doing this) when you reset the Datasource the Grid cleared the Fixed Collection and you didn't have to worry about it...this is no longer the case. If I programmatically clear the Fixed Rows Collection as expected I get no error.

Hello Ian,
Thank you for your response. I will wait for your next post.
Dave-
Just had a few seconds to look over your example. I will modify your example and get it back to you as soon as I have some more time.
I was overcome by work events and hadn't had a chance to work on your example. Rest assured I will download and get something back to you.
I am following up to see if I may be of further assistance with this issue.
Thank you for contacting Infragistics.
I created the attached sample to test this issue, but I did not reproduce it.
Please take a look at it and modify it so it does reproduce the issue. Once you have done so, please attach the modified sample to this thread so I can log this issue with our developers.
Please let me know if you have any other questions about this.
