I’ve seen this done a few different ways, but I think this is the best way because you can reuse it. Below is the converter, notice the 2 public properties.
public class BoolToTextConverter : IValueConverter
{
public string TrueText { get; set; }
public string FalseText { get; set; }
public object Convert(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)
{
return ((bool)value) ? TrueText : FalseText;
}
public object ConvertBack(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
Then in your XAML resource section you would set the properties:
<localHelpers:BoolToTextConverter x:Key="boolToTextConverter">
<localHelpers:BoolToTextConverter.TrueText>
Sent
</localHelpers:BoolToTextConverter.TrueText>
<localHelpers:BoolToTextConverter.FalseText>
Not Sent
</localHelpers:BoolToTextConverter.FalseText>
</localHelpers:BoolToTextConverter>
So this is setting the 2 public properties. The final part is to bind this to the TextBox, in this example I’m binding to a boolean property named “sent”. The result is that the text will be “Sent” if it is true and “Not Sent” if it is false.
<TextBlock Text="{Binding Path=sent, Converter={StaticResource boolToTextConverter}}"
VerticalAlignment="Center" Margin="4"
TextAlignment="Center" />
