Public Property FixedFilterCriteria As CriteriaOperator
| Type | Description |

| CriteriaOperator |
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.
