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

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.
