Format number with + and - sign

I have some WPF textblocks in a stackpanel that I want to databind and format.

E.g. the following formats a date 24h style without the seconds part:

<TextBlock Text="{Binding MyCustomObject, StringFormat={}{0:HH:mm}}" />

Now, I would like to bind an integer and also display the + and - sign (i.e. +6 or -4). 

<TextBlock Text="{Binding MyOtherCustomObject, StringFormat={}{0:+#}}" />

This however, does not work. Is this possible or do I have to write a complete converter just for this?

EDIT

Nikolays post led me to the answer:

<TextBlock Text="{Binding MyOtherCustomObject, StringFormat={}{0:+#;-#;''}}" />

In essence you provide a format for positive numbers, negative numbers and an optional part what to do with zero. In this case I stated that a zero should be displayed as an empty string.

Regards,

Michel

Try this:

<TextBlock Text="{Binding MyOtherCustomObject, StringFormat={}{0:+#;-#;''}}" />
