CustomSummaryEventArgs.FieldValue Property

Gets the processed field value.

Namespace: DevExpress.Data

Assembly: DevExpress.Data.v24.2.dll

Declaration

C#

public object FieldValue { get; }

VB.NET

Public ReadOnly Property FieldValue As Object

Property Value

Type	Description
Object	An object representing the processed field value.

Remarks

Default summary calculation algorithms process values that belong to a field specified by a summary item. When calculating a summary value manually, this column’s values are passed to corresponding event handlers via the FieldValue property. Use this property to access the processed value immediately and update the CustomSummaryEventArgs.TotalValue property value accordingly.

Note that sometimes you may need to include several fields in your summary calculations. In this case, you will need to use the CustomSummaryEventArgs.RowHandle parameter to identify the row being processed and access its values within the desired fields.
