The OpenNETCF IoC Library provides a simple and lightweight MVVM Navigation framework for Xamarin Forms application navigation (along with a lightweight DI container). I’ve blogged a couple examples on how it can be used, but I thought that a more complete example, with full downloadable source code would be a bit friendlier and easier to get your brain around.
With that, I decided to build out a very simple framework for a fairly typical application scenario. I didn’t make the views complex, nor did I do work to add graphics or anything fancy. I wanted it to show just what is necessary to show how you might go about creating the application framework and all of the navigation that would be associated.
Some highlights of what the application contains:
- A Login view that accepts a Username and Password
- A Home view that has
- A button for a menu (typically it would be a hamburger icon)
- A Summary data item that when clicked navigates to a Details view
- A slide-out left Menu that:
- Is activated by a left-to-right swipe or clicking on the menu button
- Has a button that, when clicked, navigates over to a Settings view
The application launches to a Login view. Once logged in, you end up on a Home view that has a slide-out menu in the left and a “summary” item on the main view.
In the menu is a “settings” button that will take you over to a settings screen. Clicking on the summary item in the Home View takes you over to a details view.
The source code for the example can be found in source control under the Examples/NavigationExample folder.
This sample required a couple updated to the IoC library, so you’d need to have 1.0.16215 as a minimum (which is what is in source control anyway). You can get the IoC Library right from NuGet.
