Real CustomAggregate group footer example needed.......

[540YMX]

Searched everywhere for a good example where a column with Aggregate = "Custom" performs a calculation based on the values of 2 or more other group footer values

Plenty of requests for help but replies don't really seem to get the issue and keep referring to online help/samples which don't appear to address the problem other than identifying the OnCustomAggregate event.

The closest useful example I have seen is:-

http://www.telerik.com/community/forums/aspnet-ajax/grid/how-do-the-built-in-footer-aggregate-functions-work.aspx but this only deals with manipulating the group footer value based on the line item value.

What I am interested in is to have a grid calculate the Cancel % in each footer based on values in the group footer for Total & Cancel:

Group 1
Total    Complete    Cancel    Cancel %
100            50               50         50% 
200           180              20         10%
300            225            75          25%
Group Footer 1
600            455            145        24.2%

Group 2
Total    Complete    Cancel    Cancel %
200           150             0           50% 
300           270             30         10%
400           320            80          20%
Group Footer 2
900            740          110        12.2%

Thanks
