DevExpress Filtering UI for MAUI - List form item

To use a FilterCheckedListPickerItem in your filtering UI, bind its Context property to the data control’s FilteringContext (DataGridView.FilteringContext or DXCollectionView.FilteringContext). Then specify the FilterCheckedListPickerItem’s FieldName property to set by which data source property values the data control should filter its items:

XAML

<ContentPage ...
             xmlns:dxe="clr-namespace:DevExpress.Maui.Editors;assembly=DevExpress.Maui.Editors">
             <!--...-->
                 <dxe:FilterCheckedListPickerItem Context="{Binding}" FieldName="Status"/>
             <!--...-->
</ContentPage>

FilterPage FilterPage => filterPage ??= new FilterPage() { BindingContext = dataControl.FilteringContext };

The FilterCheckedListPickerItem shows its list of options on a separate page. As an alternative, use the FilterCheckedListItem to show a checked list of available options on the same page. If you need users to select a single option, consider using a FilterRadioListItem or FilterRadioListPickerItem.

To show check boxes for items, set the ShowCheckBoxes property to True.

You can also replace the default editor with a custom editor. To do so, specify the FilterCheckedListPickerItem‘s FilterModelTemplate property. Use the FilterCheckedListPickerItem‘s FilterModel property to obtain the binding context for the template.
