Hello Everyone,

I have a problem when I try to extend a custom class from CalculatedField. I need to add a custom formula: the count of fieldA / sum of fieldB, but both always return the sum function, not the count for the first field.

protected override Telerik.Pivot.Core.Aggregates.AggregateValue CalculateValue(IAggregateValues aggregateValues)
       {
            
           var aggregateA = aggregateValues.GetAggregateValue(this.fieldA); //I need the count function here
           var aggregateB = aggregateValues.GetAggregateValue(this.fieldB); //and the sum function here


I will appreciate any sort of help greatly!

Hi Sigsa,

By design the PivotGrid uses a SumAggregate when getting the aggregated value of the RequiredField in a custom CalculatedField and you won't be able to override that behavior. However I logged that as a feature request in our Feedback portal, you can track and vote for it on the following link:
http://feedback.telerik.com/Project/143/Feedback/Details/136167-provide-an-option-to-change-the-aggregate-function-of-the-requiredfield-in-a-cust

Hope this helps. If you have any other questions or concerns, please let us know.
