Custom Aggregate for 5% of Count

[Matt]

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.
