Having hardcoded text with a binding in a TextBlock

Question

In WPF, is there any way to have the Text property of a TextBlock to contain both hard coded text and a specific binding?

What I have in mind is something along the lines of the following (ofcourse, the below doesn't compile):

<TextBlock Text="Number of Fans: {Binding Artist.Fans.Count}"></TextBlock>

There is, if you are on .Net 3.5 SP1

<TextBlock Text="{Binding Path=Artist.Fans.Count, 
                 StringFormat='Number of Fans: {0}'}" />

Is this possible to use multiple outputs, similar to args[] in the string.Format([1], [2], [3],...[n])? – Johan Aspeling Jul 12 '16 at 07:06

it's missing escaping \{0\} – WeSam Abdallah Nov 28 '17 at 20:07

In using the above approach:

<TextBlock Text="{Binding Path="Artist.Fans.Count, 
                  StringFormat='Number of Fans: {0}'}" />

I found it somewhat restrictive in that I couldn't find a way to bold face inside the StringFormat nor could I use an apostrophe in the StringFormat.

Instead I went with this approach, which worked better for me:

<TextBlock TextWrapping="Wrap">
    <Run>The value</Run>
    <Run Text="{Binding Path=MyProperty1, Mode=OneWay}" FontWeight="Bold" />
    <Run>was invalid. Please enter it with the format... </Run>
    <LineBreak/><LineBreak/>
    <Run>Here is another value in the program</Run>
    <Run Text="{Binding Path=MyProperty2, Mode=OneWay}" FontWeight="Bold" />
</TextBlock>

... or use 2 bindings in the same `TextBlock` – CAD bloke Jan 31 '20 at 00:21 — CAD bloke, Jan 31 '20 at 00:21

Use Binding.StringFormat:

<TextBlock Text="{Binding Artist.Fans.Count, StringFormat='Number of Fans: {0}'}"/>

hi Danko - would you know how to make it work with property element syntax? – BenKoshy Jul 17 '17 at 07:43

Here the binding value(clouds.all) is added with "%". You can add any value you want after "\{0\}".

 <TextBlock Text="{Binding Path=clouds.all, StringFormat=\{0\}%}"/>

Could you please [edit] in an explanation of why this code answers the question? Code-only answers are [discouraged](http://meta.stackexchange.com/q/148272/274165), because they don't teach the solution. – Nathan Tuggy Oct 29 '15 at 02:33

With XAML using Template 10 and MVVM:

Just to be clear:

By definition, binding binds values to properties of controls.
Under the MVVM paradigm as implemented in the 'Template 10' framework, the values are initialized in the ViewModel associated to the relevant XAML page.

Here is how to have hardcoded text together with a binding in a Text property:

    <Page
        ...
        xmlns:vm="using:doubleirish.ViewModels"
        xmlns:sys="using:System"
        xmlns:controls="using:Template10.Controls"
        ...

        <Page.DataContext>
            <vm:StocksViewModel x:Name="ViewModel" />
        </Page.DataContext>

        ...

        <controls:PageHeader ... Text="{x:Bind sys:String.Format('Ticker : {0}', ViewModel.Ticker)}">

    ...

    </Page>

The solution that worked for me:

<Label Content="{Binding Artist.Fans.Count}" ContentStringFormat="Number of {0}"/>

But your solution is for `Label`, not `TextBlock` as asked in the question. – Klaus Gütter Dec 27 '22 at 07:00
