How to get AutoComplete / filtering functionality for RadComboBox so that the list gets smaller as a user types?

<telerik:RadComboBox x:Name="TankComboBox"
                     IsEditable="True"
                     DisplayMemberPath="TankName"
                     ItemsSource="{Binding TanksObs}"
                     SelectedItem="{Binding SelectedTank, Mode=TwoWay}"
                     TextSearchPath="TankName"
                     Placeholder="Select tank...">
    <telerik:RadComboBox.FilterDescriptors>
        <telerik:FilterDescriptor PropertyName="TankName"
                                  Operator="Contains"
                                  IsCaseSensitive="False"/>
    </telerik:RadComboBox.FilterDescriptors>
</telerik:RadComboBox>

Hello Steve,

ComboBox does not provide filtering functionality. This is logged as a feature request here: https://feedback.telerik.com/maui/1576473-combobox-add-filtering-support 

Both controls are different controls with different implementation, so you cannot define the autocomplete filtering inside the ComboBox control. If you want to use filtering I suggest you use the AutoComplete control.
