 '''Converters''' are used to prepare application data to format a UI defined by a XAML markup. These converters make it possible to show elements only when specific conditions (like data being available) are met. This allows the creation of a good UI with XAML code only, improving code readability while also decreasing code complexity.

 In the following example, which is the same example from above, the '''StringFormatConverter''' will be additionally defined. To add more formatting possibilities, it has two extra properties, which need to be prefilled during initialization. Henceforth, these properties can be prefilled with static values or with static references.

 The usage is pretty simple: Similar to the converters, it needs to be defined in the '''Page Resources'''. Then, a '''Key''' and '''Expression''', as well as an '''ItemsSource''' have to be defined. Last, but not least, the the converter can be used within the '''ItemsSource''' property of a Syncfusion '''SfListView'''. See the following example:
