is there any documentation about the "StringFormat" property used by the PropertyAggregateDescription?
Only useful resource i found was for Kendo UI (http://docs.telerik.com/kendo-ui/framework/globalization/numberformatting).
I have no clue how to set the Format to n0 and add a postfix string (the result should look like 10,045 FOO$). I've tried "n0 'FOO$'", but it keeps ignoring the n (so i dont get any separators). "0 'FOO$'" works, but does not give me the desired number format.
