WcfInstantFeedbackSource.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.v24.1.dll
NuGet Package: DevExpress.Data
Declaration
Property Value
| Type | Description |
|---|---|
| CriteriaOperator | A CriteriaOperator object specifying the filter expression applied to data on the data store side. |
Remarks
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 WcfInstantFeedbackSource.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 WcfInstantFeedbackSource.FixedFilterString property is modified accordingly.
A data-aware control bound to a WcfInstantFeedbackSource can provide its own filtering. Changing the filter via the data-aware control does not modify the FixedFilterCriteria property and vice versa.
