After reading this article, you will learn how to add Stepper control in Xamarin.Forms Application for Android and Universal Windows Platform with XAML and Visual C# in cross platform application development.

The important tools given below are required to develop UWP.

  1. Windows 10 (Recommended).
  2. Visual Studio 2015 Community Edition (It is a free software available online).
  3. Using Visual Studio 2015 Installer, enable Xamarin (Cross Platform Mobile development and C#/.NET, while installing/modifying Visual Studio 2015.

Now, we can discuss step by step app development.

Step 1

Open Visual Studio 2015 -> Start -> New Project-> Select Cross-Platform (under Visual C#-> Blank app (Xamarin.Forms Portable)-> Give the suitable name for your app (XamFormStepper) ->OK.

Visual studio

Step 2

Now, create project “XamFormStepper_Droid”.

Visual studio

Choose the Target and minimum platform version for your Universal Windows Project.

Visual studio

Create project “XamFormStepper_UWP”.

Visual studio

Step 3

Afterwards, Visual Studio creates 6 projects and displays Getting Started.XamarinPage. Now, we have to update the Xamarin.forms Reference for Portable Project and XamFormStepper_Droid project.

Step 4

Add a XAML page for Stepper control demo. Right click on XamFormStepper(Portable) project. Select ADD-> NewItem.

Visual studio

Select ->CrossPlatform-> FormXamlPage-> Give the relevant name.

Visual studio

Step 5

  1. void OnValueChanged(object sender, ValueChangedEventArgs e) {  
  2.     lbldisp.Text = String.Format("Stepper value is {0:F1}", e.NewValue);  
  3. }  
Visual studio

Step 7

Open (double click) the file App.cs in the Solution Explorer-> XamFormStepper (portable) and set the Root page.
