Remarks

The compact panel can display predefined filter items. When clicking a filter item, the TreeListView displays only those items that meet the filter criteria.

The code sample below demonstrates how to define a set of predefined filters.

XAML

<dxg:GridControl ItemsSource="{Binding Employees}">
    <dxg:GridControl.View>
        <dxg:TreeListView CompactPanelShowMode="CompactMode" SwitchToCompactModeWidth="400">
            <dxg:TreeListView.CompactModeFilterItems>
                <dxg:CompactModeFilterItem DisplayValue="All" EditValue="" />
                <dxg:CompactModeFilterItem DisplayValue="From London" EditValue="[City] = 'London'" />
                <dxg:CompactModeFilterItem DisplayValue="From Madrid" EditValue="[City] = 'Madrid'" />
            </dxg:TreeListView.CompactModeFilterItems>
            <dxg:TreeListView.DataRowCompactTemplate>
                <!-- data template -->
            </dxg:TreeListView.DataRowCompactTemplate>
        </dxg:TreeListView>
    </dxg:GridControl.View>
</dxg:GridControl>
