{{Hint|Note how the EvalExpressionParameters have been adapted to reference a StoredProfileParameter, rather than the input control.}}

=== Item Selection ===
Filter value persistence works also when the user input method is to select an item from a picker.
<tabs>
<tab name="Xamarin">
<source lang = "xml">
<controls:PickerExt
x:Name="ExamplePicker"
ItemsSource="{Binding Children.Items[0].PropertyItems[PROPERTY].MetaProperty.SelectiveList, Converter={StaticResource SelectiveListToItems}, TargetNullValue='', FallbackValue=''}"
ItemDisplayBinding="{Binding DisplayText}"
SelectedValuePath="Value"
SelectedValue="{Binding StoredProfileParameters[key]}"
SelectionChangedCommand="{Binding StoreProfileParameterCommand}"
SelectionChangedCommandParameter="{Binding SelectedItem.Value, Source={x:Reference ExamplePicker}, StringFormat='key={0}'}"/>
</source>
</tab>

== Known Issues ==
** If filtering a GUID property, ensure the same values are compared; DisplayString if the user is inputting readable text, UID if the user has selected an item from a list.
