Andre's example will work great. This is a common question so I also  
created a lesson that shows how to create a custom property for your  
data grid that returns aggregate values. The example uses the dgData  
property which will be faster than using the dgText property.

You should note that adding values in "FillInData" won't provide  
accurate information since FillInData is called multiple times for  
each row as you scroll through the data in the data grid.
