When data binding two elements together, how can I include the binding information AND text as in the case below where I want my label to say:

The font size is 8.5

<Grid>     <StackPanel>         <Slider Name='theSlider' Margin='5' Minimum='8' Maximum='14'></Slider>         <Label Content='The font size is: {Binding ElementName=theSlider, Path=Value}' FontSize='{Binding ElementName=theSlider, Path=Value}'></Label>     </StackPanel> </Grid>

Thank you, so here is the solution using ContentStringFormat in .NET 3.5:

<Grid>     <StackPanel>         <Slider Name='theSlider' Margin='5' Minimum='8' Maximum='14'></Slider>         <Label Content='{Binding ElementName=theSlider, Path=Value}' ContentStringFormat='The font size is {0}.'/>     </StackPanel> </Grid>

    If you’re using 3.5 SP1 you can use the StringFormat property in your Binding: http://blogs.msdn.com/llobo/archive/2008/05/19/wpf-3-5-sp1-feature-stringformat.aspx
