WPF padding with StringFormat - wpf

Question

How can I pad a string in wpf by means of StringFormat?
I'm using a multibinding:
<MultiBinding StringFormat="Name: {0}, age: {1}">
<Binding Path="Name"/>
<Binding Path="Age"/>
</MultiBinding>
Is there any way to pad the string such that column Age begins at position 50 for instance? I am looking for something that is similar to
string.PadLeft(50)

Answer 1

You should be able to pad your value in the string format like this:
<MultiBinding StringFormat="Name: {0}, age: {1,50}">
<Binding Path="Name"/>
<Binding Path="Age"/>
</MultiBinding>
However, you should note that your request is not how padding works. Instead of starting at position 50, the Age value will be padded with 50 spaces after the Name value.
There is no way that I am aware of that will enforce an exact starting position for your Age value when it is in a MultiBinding, unless it is the first value to be data bound. Also, this will only pad the actual value and not the age text.

Other way may be to use Converter:
public class PaddingConverter : IMultiValueConverter
{
public int Width { get; set; }
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
string name = values[0] as string;
string age = values[1] as string;
var text = String.Format("Name: {0}, age: {1}", name, age);
return text.PadLeft(Width);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
and your xaml:
<local:PaddingConverter x:Key="PaddingConverter" Width="50"/>
<MultiBinding Converter={StaticResource PaddingConverter}>
<Binding Path="Name"/>
<Binding Path="Age"/>
</MultiBinding>
