Does Silverlight support StringFormat in binding?

Question

I know that WPF 3.5 SP1 supports a StringFormat in a binding, but can Silverlight do the same? I thought it could, but damned if I can make it work!

Here's a snippet of my XAML:

<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding StartTime, StringFormat=t}" />

It compiles OK, but I get a runtime error when it gets to the browser...

Answer 1

It does not but you can use a Value Converter and specify the ConverterParamenter in the binding. You'll have to create your own Value Converter by deriving a class from IValueConverter like I've shown here. Michael

Answer 2

Thanks Michael.

Yes, I've already gone down the IValueConverter route.

It just gets a little confusing when working in both WPF and Silverlight as to what's supported in each environment! :-)

Answer 3

I don't know which version of Silverlight introduced it, but you now can. I'm using Silverlight 4 Beta.

   <data:DataGridTextColumn Header="Date" 
     Binding="{Binding CreateDt, StringFormat=\{0:d\}}" />

Here's info on Formatting Types, and more for DateTime.

Here's full documentation on Silverlight Binding.

Answer 4

The string format noted by Simon is in Silverlight 4. There is even support in Blend for setting the format.
