How to add additional text (or string) to a binding in xaml

Question

I have this:

<Label Text="{Binding Height}" AbsoluteLayout.LayoutBounds=".9,.17,-1,-1" TextColor="White" AbsoluteLayout.LayoutFlags="PositionProportional" HorizontalTextAlignment="Center" HorizontalOptions="Center" FontSize="Medium"/>

Obviously {Binding Height} takes up the entire text.

The binding is currently a double, and needs to remain so, I just need to concat an 'm' at the end to represent meters.

I have tried {Binding Height} m and {Binding Height + m} but obviously xaml doesn't work the same way a regular string concatenation would work.

Answer 1

Try using StringFormat. Like this:

Text="{Binding Height, StringFormat='{}{0}m'}"

Edited for clarity:

You can write anything you want after the {0} argument.

For example, the above will produce values like 25m, 10m etc.

You can write something like this if you like:

Text="{Binding Height, StringFormat='{}{0} is a good number.'}"

The above will produce, for example:

10 is a good number.
