Customizing Group Expression

[Mazdak]

I'm Customizing Group Header expression like this demo page:

http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/expressions/defaultcs.aspx

I have a TotalCharge field which shown its Sum in footer, I also want when I make this field grouped, Sum of group also shown in Header text.

The problem is I use drag and drop columns to do the grouping so don't know how to make it works.

I think I should do it some how with GroupChanging event. Could you please help me make this works?

Regards
Mazdak
