How to bind multiple values to a single WPF TextBlock

Question

I m currently using the TextBlock below to bind the value of a property named Name    lt TextBlock Text   Binding Name     gt    Now  I want to bind another property named ID to the same TextBlock   Is it possible to bind two or more values to the same TextBlock  Can it be done with simple concatenation  like Name   ID and  if not  how else could this be approached

I know this is a way late  but I thought I d add yet another way of doing this   You can take advantage of the fact that the Text property can be set using  Runs   so you can set up multiple bindings using a Run for each one  This is useful if you don t have access to MultiBinding  which I didn t find when developing for Windows Phone    lt TextBlock gt     lt Run Text  Name      gt     lt Run Text   Binding Name    gt     lt Run Text    Id     gt     lt Run Text   Binding Id    gt   lt  TextBlock gt

If these are just going to be textblocks  and thus one way binding   and you just want to concatenate values  just bind two textblocks and put them in a horizontal stackpanel        lt StackPanel Orientation  Horizontal  gt           lt TextBlock Text   Binding Name    gt           lt TextBlock Text   Binding ID    gt       lt  StackPanel gt    That will display the text  which is all Textblocks do  without having to do any more coding   You might put a small margin on them to make them look right though

Use a ValueConverter   ValueConversion typeof string   typeof String    public class MyConverter  IValueConverter       public object Convert object value  Type targetType  object parameter  CultureInfo culture                return string Format   0   1     string  value   string  parameter              public object ConvertBack object value  Type targetType  object parameter  CultureInfo culture                 return DependencyProperty UnsetValue            and in the markup   lt src MyConverter x Key  MyConverter   gt            lt TextBlock Text   Binding Name  Converter  StaticResource MyConverter Parameter ID      gt

You can use a MultiBinding combined with the StringFormat property  Usage would resemble the following    lt TextBlock gt       lt TextBlock Text gt               lt MultiBinding StringFormat     0     1   gt               lt Binding Path  Name    gt               lt Binding Path  ID    gt           lt  MultiBinding gt       lt  TextBlock Text gt   lt  TextBlock gt    Giving Name a value of Foo and ID a value of 1  your output in the TextBlock would then be Foo   1   Note  that this is only supported in  NET 3 5 SP1 and 3 0 SP2 or later
