Aggregates Overview

Updated over 6 months ago

The DataGrid exposes an Aggregates API through the RadDataGrid.AggregateDescriptors property where you can add PropertyAggregateDescriptors or DelegateAggregateDescriptors.

The PropertyAggregateDescriptor enables you to utilize a set of available functions, while the DelegateAggregateDescriptor allows you to implement a custom function through the IAggregateFunction interface.

The PropertyAggregateDescriptor supports the following KnownFunction aggregates:

• Sum—The SUM function.
• Min—The MINIMUM function.
• Max—The MAXIMUM function.
• Average—The AVERAGE function.
• Count—The COUNT function.
• Product—The PRODUCT function.
• StdDev—The STANDARD DEVIATION, based on a sample function.
• StdDevP—The STANDARD DEVIATION, based on the entire population function.
• Var—The VARIANCE, based on a sample function.
• VarP—The VARIANCE, based on the entire population function.
