GridSummaryItem.SummaryType Property

Gets or sets the aggregation function type.

Namespace:DevExpress.XtraGrid
Assembly:DevExpress.XtraGrid.v17.2.dll

Expanded Syntax

Property value

Type: SummaryItemType
A DevExpress.Data.SummaryItemType enumeration value specifying the summary type.
The default is SummaryItemType.None.

Expanded Remarks

Use the SummaryType property to specify the type of aggregate function used to calculate the summary value. The following predefined aggregate functions are available:

  • sum;
  • minimum value;
  • maximum value;
  • average value;
  • the number of records.

These five aggregate functions do not limit the types of summaries you can use. You can implement your own aggregate functions. For this purpose, set the SummaryType property to the DevExpress.Data.SummaryItemType.Custom value and write a GridView.CustomSummaryCalculate event handler.
