Using and Creating Behaviors for your UI controls in Xamarin Forms

Don't you wish you could add functionality to UI controls without having to subclass them and do all kinds of complex stuff? You can with Behaviors!
In this video we see what Xamarin.Forms Behaviors are. We will learn how to consume them in your own code, but also how to create them yourself!

Are you using behaviors in your code right now? What do they do? And what can I do to persuade you to contribute them to the XamarinCommunityToolkit? ;)

[@LeonardHarrisLH]

Subbed, love Xamarin.Forms, love your content! :D

[@jfversluis]

Welcome aboard! Thanks so much :D

[@fidhalkotta]

Great Content! Easy to follow and very informative.

[@jfversluis]

Thank you Fidhal! Glad you like it :)

[@TheDaple]

Awesome! Just what I needed.

[@jfversluis]

Glad I could help!

Unfortunately only now came across this video of yours. It is once again super structured and also goes into great detail.
What do you think Gerald, can I use an AnimationBehavior also for a shimmer effect? Since I assemble my skeletons myself, these are always just static gray bars. There is still a shimmer missing, that would be a good idea or?

[@jfversluis]

Thank you so much David!
Why are you rolling your own? You know there is stuff that you can use out there for this, right? :)

[@HD_CyberSecInsights]

@@jfversluis Yes I know there are libraries for this however I have not been able to get it to work in combination with .
So I had to make a workaround and design my own skelton
Do you have a better solution?

[@Guru1413]

@Gerald,
Could you let us know what is the best way to validate the entire form like ui in Xamarin forms

[@jfversluis]

Great question! I’ll see to add a video on that :)

[@estebanperalta8880]

Great video! I have a image that I use as a button, and I want to hide it after it's been tapped. How can this be achieved?

[@jfversluis]

Create a behavior that hooks into the tapped handler and hide the parent control when that event is fired!

I’m sorry I’m not sure what you mean by this
