GridSummaryItem.FieldName Property

Gets or sets the name of a dataset field whose values are used for summary calculation.

Namespace:DevExpress.XtraGrid
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Property value

Type: String
A string value specifying the name of a data field whose values are used for summary calculation.

Expanded Remarks

If the SummaryType property value is DevExpress.Data.SummaryItemType.Count, you can leave the FieldName property set to an empty string (or set to any other value). If the SummaryType property value is DevExpress.Data.SummaryItemType.Custom, setting the FieldName property value is optional. If you want to use the GridView.CustomSummaryCalculate event's DevExpress.Data.CustomSummaryEventArgs.FieldValue parameter, you must initialize the FieldName property with the required field name. If you don't want to use the this parameter, the FieldName property can be set to any value.

If the SummaryType property is set to DevExpress.Data.SummaryItemType.Min, DevExpress.Data.SummaryItemType.Max, DevExpress.Data.SummaryItemType.Sum or DevExpress.Data.SummaryItemType.Average, the FieldName property must specify the name of a field bound to the column whose values must be used when calculating. Otherwise, no summary will be calculated.
