    I have the following aggregate to calculate the count of people in my data.


    radPivotGrid1.AggregateDescriptions.Add(new PropertyAggregateDescription()
    PropertyName = "personId",
    AggregateFunction = AggregateFunctions.Count


    I want to add a custom aggregate that calculates 5% of the count, always rounding up to the next integer value. For example, if there were 102 people, the customer aggregate would yield 6. (102 * 5% = 5.1 rounded up = 6)

    How can I do this?

    Hello Matt,

    Thank you for writing.

    In order to achieve your task, you would need to create a custom aggregate function. We have a documentation article providing an example: RadPivotGrid | Custom Aggregation.

    I hope this information is useful. Should you have further questions please do not hesitate to write back.
