GridViewExpressionColumn and GroupDescriptors issue

[Alan]

Hi,

I have an issue where I have groupDescriptors defined on a Grid.
I added a GridViewExpressionColumn with a custom AggregateFunction using the code provided in this thread:
http://www.telerik.com/community/forums/wpf/gridview/aggregate-column-footers-don-t-sum-on-data-change-caliburn-micro-mvvm.aspx 

The AggregateFunction calculation works at the Grand Total level, but not at the GroupDescriptor level.

See screenshot attached. (2nd one)

Did somebody ever encountered the problem before?

Thank you,
Alan

Hello Alan,

 
In case you have added a group descriptor to RadGridView, it would be the expected behavior. I would suggest you to use a ColumnGroupDescriptor. Please take a look at this help article for a reference.

Hi Vera,

thanks for your quick reply.
It works beautifully, however I am now having this bug:

Do you have a temporary way to have a column grouped without showing it?

Thank you,
Alan

Nevermind, I see that it has been fixed in the last release.
