How to use stringformat in multibinding in WPF XAML

As you know StringFormat is of great importance for data representation in WPF. My problem is how to use StringFormat when multibinding in WPF?

If I give a very simple example:

We have variables,which are A and B and whose values are 10.255555 and 25.6999999

And we want to show them 10.2,25.6?

How can I do this with multibinding? Normally it is piece of cake with ValueConverter

Any help and ideas on this topic will be greately appreciated


Just set the StringFormat property on the MultiBinding; use placeholders ({0}, {1}...) for each binding in the multibinding, and include format specifiers if necessary (e.g. F1 for a decimal number with 1 decimal digit)

        <MultiBinding StringFormat="{}{0:F1}{1:F1}">
            <Binding Path="A" />
            <Binding Path="B" />

The {} part at the beginning is the format string is an escape sequence (otherwise the XAML parser would consider { to be the beginning of a markup extension)

To simplify you could use two TextBlock/Labels to display the values.

If you are using .Net4, you can bind in a Run Inline element of a TextBlock

    <Run Text="{Binding A, StringFormat={}{0:F1}}"/>
    <Run Text="{Binding B, StringFormat={}{0:F1}}"/>

If anyone is looking for "Time Formats" this is for 24hr Clock which is how I came to this post:

<TextBlock TextAlignment="Center">
        <MultiBinding StringFormat="{}{0:HH:mm} - {1:HH:mm}">
             <Binding Path="StartTime" />
             <Binding Path="EndTime" />

The leading 0: and 1: are the reference to the Bindings

[0:hh:mm tt] to display AM/PM
