Namespace: DevExpress.Maui.CollectionView
Assembly: DevExpress.Maui.CollectionView.dll
NuGet Package: DevExpress.Maui.CollectionView
Declaration
public string FilterString { get; set; }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:
<dxcv:DXCollectionView ItemsSource="{Binding Recents}"
FilterString="StartsWith([Name], 'M')">
<!-- ... -->
</dxcv:DXCollectionView>
