How to add a thousands separator to a Binding of a Multibinding?

Question

So I have this XAML:

 <TextBlock.Text>
     <MultiBinding StringFormat="SomeText: &#x09;{0}&#x0a;SomeOtherText: &#x09;&#x09;{1}">
          <Binding Path="SomeBoundVar" />
          <Binding Path="AnotherBoundVar" StringFormat="{}{0:N2}" />
     </MultiBinding>
 </TextBlock.Text>

And I'd like to add a thousand separator to the 2nd binding (the StringFormat as above doesn't work). How can I do that ? Or do I have to use a converter ?

Answer 1

I had a same kind of issue and following is the way I fixed.

 <TextBlock>
       <TextBlock.Text>
           <MultiBinding StringFormat="{} Balance {0} : {1:##,#0.00}">
                  <Binding Path="Currency"/>
                  <Binding Path="Balance"/>
           </MultiBinding>
       </TextBlock.Text>
  </TextBlock>

Sample Result

Balance AED : 2,456.45
