I’ve used the Xamarin.Forms Button in a number of projects and while it has slowly improved (adding support for images etc) it’s still lacking in a few areas. Recently I needed to add support for wrapping and truncation options and these are mysteriously absent from the stock control.
For inspiration I looked at the Label control as this has a LineBreakMode property which allows you to use a variety of truncation or wrapping modes. This seemed perfect and rather than re-invent the wheel I set about adding the same property to the Button. Both iOS and Android support these options via LineBreakMode and Ellipsize properties respectively. Along the way I found it was necessary to improve the logic on iOS for sizing to fit content and the InTheHand.Forms.FormattedButton was born. I was also able to use this opportunity to fix a niggly issue with the iOS button where it fitted the label to the full width of the button so if you used a background the text was jammed against the left/right edges which looks ugly.
It’s intuitive to use from XAML:-
<cc:MyButton LineBreakMode="WordWrap" Text="This is a wrapping button with no other special properties set just a single long descriptive text value"/>
