How to do Multibinding in metrostyle app ?

Question

Is Multibinding supported? If so the below code is not compiling.

<TextBlock>
                            <TextBlock.Text>
                                <MultiBinding  StringFormat="{}{0} ({1})">
                                    <Binding Path="LongName"/>
                                    <Binding Path="ShortName"/>
                                 </MultiBinding>

                            </TextBlock.Text>
                        </TextBlock>

 

Thanks,

Answer 2

I can't find MultiBinding in the consumer preview either.  When can we expect to see it?

Answer 3

Multibinding is not implemented in WinRT

Answer 4

PLEASE, PLEASE, PLEASE put Multibinding at the top of the priority list after RTM!  I am wasting a lot of time adding in hundreds of lines of code and hacks to work around the lack of multibinding.  Along with relativesource ancestor, are absolutely key to be able to use the magnificent data binding facilities that are part of XAML!

Answer 5

I was also a little disappointed to see the blue line show up below my MultiBinding declaration. Hope we can get this in the next version.

Answer 6

I was looking for a way to bind to multiple visual states, and thought of MultiBinding at first.  But then I found a blog post that demonstrates Peter Blois's BindingListener class.  I succeeded in applying it in a Metro-style app as seen in my answer to my question on the subject.  So you can apply BindingListener in your specific situation, or perhaps create your own general-purpose MultiBinding class with it.

Answer 7

I am also desperately waiting for MultiBinding; please consider adding it to WinRT in the RTM build.
