Join James Timberlake for an in-depth discussion in this video Implement a behavior, part of Extending Xamarin with Behaviors, Commands, and Triggers.
- [Instructor] Okay, now we have our behavior…properly coded and ready to go.…We just need to add it to a View.…Let's get started on that.…Here we have our AddTodoPage,…and as you can see if we go to our preview,…it takes a name and date…in order to create a to do item.…What we want to do here is take the name date…and make sure it only has uppercase letters.…Let's do that with our behavior.…I'm going to take this preview away,…and the first thing I'm going to do…is I'm going to create a namespace…that we can use to reference our behavior.…
Some people like to put this in their code…before files instead of XAMLs.…I like to use XAMLs because it's a clear representation…of what your View should be doing.…So no one has to go inside of your CS files…in order to make sure what your view logic is.…I'm setting a namespace here Todo.Behaviors.…How do I know which namespace to use?…If I go to EntryAllUppercase and choose the namespace,…it's right there for me.…Now to attach the behavior to the entry View.…
We're going to find our name entry view,…
