Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.PivotGrid.v23.2.Core.dll

NuGet Packages: DevExpress.PivotGrid.Core, DevExpress.Win.Navigation

Declaration

C#

[DefaultValue(UnboundExpressionMode.Default)]

VB.NET

<DefaultValue(UnboundExpressionMode.Default)>
Public Property UnboundExpressionMode As UnboundExpressionMode

Property Value

Type	Default	Description
UnboundExpressionMode	Default	An UnboundExpressionMode object that specifies how the specified data field’s unbound expression is calculated.

Available values:

Name	Description
Default	The default parameter value.
UseSummaryValues	An unbound expression is calculated against summary values.
DataSource	An unbound expression is calculated against each data source record, and then the resulting values are summarized.
UseAggregateFunctions	An unbound expression is calculated using aggregates.

Remarks

Note

This member is not supported in Optimized, OLAP, and Server modes. Use ExpressionDataBinding/OlAPExpressionBinding instead.

By default, the unbound expression is calculated against each data source record, and then the resulting values are summarized. If necessary, you can calculate unbound field values on the visualization (or summary) level. You can also use a specified set of summary functions (such as Sum, Avg, etc.) to summarize data source records. The UnboundExpressionMode property allows you to specify the mode used to calculate unbound field values.
