Property Value

Type	Description
String

A string that specifies a filter criteria applied to data the DXCollectionView displays.

Remarks

When you apply a filter, the view displays a subset of items that meet the specified criteria. You can filter data in the DXCollectionView against single or multiple data fields.

To create filter expression strings, use Criteria Language.

You can also set the FilterExpression property to specify a filter expression. Note that the FilterExpression and FilterString properties are dependent. If you update one of them, the other changes as well.

Call the CriteriaOperator.Parse method to convert a filter string to its CriteriaOperator equivalent.

Example

The following example filters out persons whose name starts with the letter M:

XAML

xaml

<dxcv:DXCollectionView ItemsSource="{Binding Recents}"
                       FilterString="StartsWith([Name], 'M')">
    <!-- ... -->
</dxcv:DXCollectionView>
