=== Definition ===In Xamarin, before converters can be used, they need to be defined in the page's ''Resources'' tag. Make sure to include the <code>UBIK.CPL.Converters</code> namespace in the namespace definitions!The following example shows how the <code>NullToBoolConverter</code> can be defined:<syntaxhighlight lang="xml"><ContentView x:Class="UBIK.CPL.Resources.UBIKChildArea" xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:converters="clr-namespace:UBIK.CPL.Converters;assembly=UBIK.CPL"> <ContentView.Resources> <ResourceDictionary> <converters:NullToBoolConverter x:Key="NullToBool" /> </ResourceDictionary> </ContentView.Resources> <!-- Cuztomizing --> </ContentView></syntaxhighlight>The key ''NullToBool'' makes this converter accessible from the customizing in this page.===Usage===This description A converter can only be used in conjunction with a <code>{Binding}</code>. The following is an easy example, showing how the ''NullToBool'' converter, defined above, can be used.<syntaxhighlight lang="xml"><Label Text="My Text" IsVisible="{Binding MyBindableProperty, Converter={StaticResource NullToBool}}"/></syntaxhighlight>If '''MyBindableProperty''' is ''null'' or an empty string, the converter will follow soonreturn '''true''', making the Label visible! === Parameter ===Some converters accept a '''ConverterParameter''', that passes additional information. Closely read the description of the available converters to find out which accept or even require a parameter to work properly. In Ubik, some converters accept a string parameter, consisting of multiple individual parameters separated by <code>|</code>.
