Any built in way to format WPF bindings?

Scenario

I can't seem to find a way to format bindings in WPF using an IFormatProvider. Currently I've a property on my data source:

public int PersonNumber { get; set; }

This property is bound to a Label in XAML:

<Label Content="{Binding Path=PersonNumber}" />

As you can see it's a number, but should be formatted like 0000.00.000. Currently we use a separate IFormatProvider for such things in our old WinForms application.

Questions

• Is formatting like this possible in WPF?
  • If yes, our preferred way is to still use an IFormatProvider, also possible?
  • If开发者_开发百科 no, what is a good alternative?

Thanks in advance!

You're looking for the ContentStringFormat property, which is on all ContentControl descendants including Label.

<Label Content="{Binding PersonNumber}" ContentStringFormat="000" />

I'm not sure whether WPF's formatting can make use of an IFormatProvider, though.

And to be complete, you could just add a String property to your ViewModel to get full control in C#:

public int PersonNumber { get; set; }
public string PersonNumberText { get { return ... } }

You can use the property StringFormat of Binding

In addition to the posted answers, there's always available the converter way.
