Introduction
In this tip, I would like to share the code that I have written for converting numeric value to its words format. It is a very simple prototype and can be extended to be used as a full fledged application or user control.
In this example, I have a list of numbers which is to be populated in combo box. At the time of displaying numbers in combo box, they should be shown in words. For example, 1 -> one, 2 -> two …..
For this purpose, I have created a Data Converter inherited from IValueConveter interface provided by the WPF library.
public class DataConverter : IValueConverter
Whenever any class is implementing IValueConverter, it needs to implement two methods provided by interface:
public object Convert(object value, Type targetType,
object parameter, System.Globalization.CultureInfo culture)
public object ConvertBack(object value, Type targetType,
object parameter, System.Globalization.CultureInfo culture)
In Convert method, I have written the logic to convert numeric value into words and return the string.
Coming to the UI side, the window contains just a combo box to be populated with list using data context (binding). The list contains all the numbers, hence we need to put converter to convert numeric values to words.
<ComboBox
ItemsSource="{Binding list,
Converter={StaticResource DataConverter}}">
Finally the application looks like:
