Custom Master Detail Page in Xamarin.Forms using Fresh MVVM

Introduction:

In this tutorial, we will learn how to use master detail page using Fresh MVVM with FreshNavigationContainer. It has some work around for creating master detail page more than creating master detail page using FreshMasterContainer. In my previous tutorials, we have learned the method to create master detail page using Fresh Master Container. To know more, visit my previous article.

Kindly refer my previous article on Fresh MVVM to know the basics & rules of Fresh MVVM.

Coding Part:

Steps:

I have split this part into 3 steps as in the following.

  1. Creating new Xamarin.Forms Projects.
  2. Setting up the plugin for Xamarin.Forms Application.
  3. Implementing Fresh MVVM.

Step 1: Creating new Xamarin.Forms Projects

Create New Project by Selecting New -> Project -> Select Xamarin Cross Platform App and Click OK.
Then Select Android and iOS Platforms as shown below with Code Sharing Strategy as PCL or .Net Standard and Click OK.

Step 2: Setting up the plugin for Xamarin.Forms Application

We will start coding for Fresh MVVM. Create New Xamarin Forms Project. Open Nuget Package Manager against the solution and do search for Fresh MVVM Plugin or Paste the following Nuget Installation.
Install-Package FreshMvvm -Version 2.2.3
Click Install to install this Plugin against your PCL Project or .NET standard Project.

Step 3: Implementing Fresh MVVM.

  1. Create your XAML page (view) with name ended up with “Page”.
  2. Create PageModel by create Class name ended with “PageModel” and inherited with “FreshBasePageModel” as shown below screenshot.

In the same way, I have created pages “MyMasterDetailPage”, “MasterPage”, “Detail1Page” and “Detail2Page” with two respective models “MyMasterDetailPageModel”, “MasterPageModel”, “Detail1PageModel” and “Detail2PageModel”.

Here,
MyMasterDetailPagecontainer to have both Master & Detail page
MasterPageMaster or Menu Page
Detail1Page, Detail2PageDetail pages of the Master detail page

Set MainPage:

We need to set the MainPageModel as MainPage using FreshNavigationConatiner.

  1. Open App.xaml.cs or App.cs and set MainPage.
    // To set MainPage for the Application
    var page = FreshPageModelResolver.ResolvePageModel();
    var basicNavContainer = new FreshNavigationContainer(page);
    MainPage = basicNavContainer;
  2. Then add button with command for opening the MasterDetailPage from MainPage.
    public Command GotoSecondPageCommand
    {
        get
        {
            return new Command(async () =>
            {
                await CoreMethods.PushPageModel();
            });
        }
    }
  3. Open MyMasterDetailPage and add Master, Detail page to the constructor of the page like below.
    public MyMasterDetailPage()
    {
        InitializeComponent();
    
        NavigationPage.SetHasNavigationBar(this, false);
    
        Master = FreshPageModelResolver.ResolvePageModel();
        Detail = new NavigationPage(FreshPageModelResolver.ResolvePageModel());
    }
  4. Then click “Run” to see your Custom Master Detail Page using FreshMVVM with FreshNavigationContainer.

By this way, we can have Navigation Service & Stack for all type of Pages. Kindly find the screenshot for your reference.

Master Detail Page in Xamarin.Forms using Fresh MVVM


Introduction:

In this tutorial, we will learn how to perform MVVM approach in Xamarin.Forms using Fresh MVVM. MVVM approach is the best approach for Xamarin.Forms and WPF Applications. There are a lot of MVVM plugins or libraries like FreshMVVM, MVVMCross, Prism, etc. available to simplify MVVM implementations.

FreshMVVM:

FreshMVVM is designed to perform MVVM easy and simple with Xamarin.Forms Application. It is created Michael Ridland. It has certain rules to perform MVVM Databinding. You can find the plugin from GitHub and Nuget.

Kindly refer my previous article on Fresh MVVM to know the basics & rules of Fresh MVVM.

  2. Create PageModel by create Class name ended with “PageModel” and inherited with “FreshBasePageModel” as shown below screenshot.
  3. In the same way, I have created two pages “Detail1Page” and “Detail2Page” with two respective page models “Detail1PageModel” and “Detail2PageModel”.
Set MainPage:
To create Fresh MVVM Master Detail Page as MainPage, we should use Fresh Master Detail Navigation Container with the following code. Open App.xaml.cs or App.cs and set MainPage.
var masterNavigation = new FreshMasterDetailNavigationContainer();
masterNavigation.Init("Menu");
masterNavigation.AddPage("First Page", null);
masterNavigation.AddPage("Second Page", null);
MainPage = masterNavigation;
  • Here, we will not discuss about navigation between pages. If you want to know, you can see my previous article on Fresh MVVM.
Full Code for App.xaml.cs:
You can find the code for App.xaml.cs below
public partial class App : Application
{
    public App()
    {
        try
        {
            InitializeComponent();
            var masterNavigation = new FreshMasterDetailNavigationContainer();
            masterNavigation.Init("Menu");
            masterNavigation.AddPage("First Page", null);
            masterNavigation.AddPage("Second Page", null);
            MainPage = masterNavigation;
        }
        catch (Exception ex)
        {

        }
    }

    protected override void OnStart()
    {
        // Handle when your app starts
    }

    protected override void OnSleep()
    {
        // Handle when your app sleeps
    }

    protected override void OnResume()
    {
        // Handle when your app resumes
    }
}
