I've read the blog http://blogs.infragistics.com/blogs/devin_rader/archive/2010/01/07/creating-custom-summery-operands.aspx
We use xamGrid 11.1
It's working fine for data in grid.DataSource. We have UnboundColumn with ValueConverter and this value doesn't have a property in DataSource. So I can't get this value in method Summarize() in custom SynchronousSummaryCalculator. Is there any way to work with such properties?
Hello,

where a similar issue like yours is discussed. Please let me know if this helps you or you need further assistance on this matter.
Looking forward for your reply.
Thanks for reply.
I solved the problem by adding one more contructor for Operand and Calculator. I get full UnboundColumn with its ValueConverter and get the result one more time to summarize it.
