#Property Value

Type Description
CriteriaOperator

The filter criteria created by the FilterBehavior.

#Remarks

The following code sample shows how to use the FilterBehavior to allow the Filter Elements to work with the ListBoxEdit.

<dxe:ListBoxEdit Name="listBoxEdit" ItemsSource="{Binding Products}"
                 FilterCriteria="{Binding ElementName=filterBehavior, Path=ActualFilterCriteria}"/>

<!-- -->    

<dxfui:CheckedListFilterElement FieldName="CategoryName">
    <dxmvvm:Interaction.Behaviors>
        <dxfui:FilterBehavior x:Name="filterBehavior" ItemsSource="{Binding ElementName=listBoxEdit, Path=ItemsSource}">
            <dxfui:FilterField FieldName="CategoryName">
                <dxe:ComboBoxEditSettings ItemsSource="{Binding Categories}"/>
            </dxfui:FilterField>
        </dxfui:FilterBehavior>
    </dxmvvm:Interaction.Behaviors>
</dxfui:CheckedListFilterElement>

Run Demo: FilterBehavior

Use the FilterString / FilterCriteria property to create a filter expression that consists of multiple conditions applied to multiple columns, and apply it to the FilterBehavior. Setting the FilterString / FilterCriteria property to a new value clears any filters that have been previously applied.
