WcfServerModeSource.FixedFilterCriteria Property

Specifies the criteria used to filter objects on the data store side. These criteria are never affected by bound data-aware controls.

Namespace: DevExpress.Data.WcfLinq

Assembly: DevExpress.Data.v23.1.dll

NuGet Package: DevExpress.Data


public CriteriaOperator FixedFilterCriteria { get; set; }

Property Value

Type Description

A CriteriaOperator object specifying the filter expression applied to data on the data store side.


For information and examples on how to create criteria, see Creating Criteria.

You can also specify a string representation of the filter criteria via the WcfServerModeSource.FixedFilterString property. These two properties are synchronized. When a filter expression is assigned to the WcfInstantFeedbackSource.FixedFilterString property, an equivalent CriteriaOperator is created and assigned to the FixedFilterCriteria property. When a CriteriaOperator is assigned to the FixedFilterCriteria property, the WcfServerModeSource.FixedFilterString property is modified accordingly.

A data-aware control bound to a WcfServerModeSource can provide its own filtering. Changing the filter via the data-aware control does not modify the FixedFilterCriteria property and vice versa.
