Changes

* Require a custom [[SYSCLS_CHILDAREATEMPLATE|Child Area template name]] to work. This customizing will not work applied to the UBIKChildArea.

* Work directly on the Children.Items collection. While filters are active, anything derived from this collection (such as Children.Items.Count or custom datasources like [[XAML_Changes_in_UBIK_WinX_3.5#Filtering_by_expressions|ListCollectionView]] / [[Xamarin_XAML#Content_filtering|sfDataSourceExt]]) will also be affected.

== Usage ==

* ClearPropertyFilters: Clear out all existing filters at the current level before executing the command. This is optional and defaults to false;

* All other parameters: KeyValue pairs used as filter criteria where the Keys are the names of the metaproperties by which you want to filter.

==== ItemsSource ====

Note that you will then need to remove references to the DisplayText, as the x:String value becomes the value used to filter.

==== GUID Properties ====

<br>

Note that in this example, a Properties.AllItems[LK_PLANT_QUERY] is added to the Content object to provide the list of items displayed by the Picker, as a workaround to the Children.Items[0] approach.

== Displaying Results ==

</Entry.Behaviors>

</source>

<br>

{{Hint|"&amp;quot;" and "\" are used for escaping the special characters in XAML and C# code respectively. "{0}" and "{1}" are placeholders and get replaced by the property name and the filter value. The end expression being executed in this example is <code>Content["PROPERTY_NAME"].Value.ToString().Equals(FILTER_VALUE)&#61;&#61;true</code>}}
