Introduction

Xamarin is a platform to develop cross-platform and multi-platform apps (for example, Windows phone, Android, iOS). In Xamarin platform, the code sharing concept is used. In Xamarin Studio, Visual Studio is also available.

 
 
Frame
  1. HasShadow = true or false, to indicate whether to show a shadow effect where the platform supports it.
  2. OutlineColor = A color specification, with or without the prefix, "Color". For example, "Color.Red" and "Red" both specify the color red.
Prerequisites
  • Visual Studio 2017 (Windows or Mac)
The steps given below are required to be followed in order to use Border Shadow Effect in your controls in Xamarin.Forms application.

Step 1

Go to Visual Studio for Mac.

Click New Solution >> Multiplatform >> App >>  Blank Forms App. Afterwards, click "Next".

 
 
Step 2

In this step, configure your app. Give the App name (Ex: sample) and Organization Identifier. Afterwards, click "Next".

 
 
Step 3

In this step, give your project name (Ex: Sample) and solution name (Ex: Sample). Give the path to your project. Afterwards, click "Create".

 
 
Step 4

Subsequently, go to the solution. In there, you get all the files and sources of your project (PCL). Now, select XAML page and double-click to open the MainPage.Xaml page.



Step 5

In this step, create a Label without any border shadow effect.
 
 
MainPage.xaml
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XamarinForms_Frame" x:Class="XamarinForms_Frame.XamarinForms_FramePage">  
  3.     <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />  
  4.     <ContentView>  
  5.         <StackLayout HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">  
  6.             <Label Text="Hello Xamarin Forms."></Label> </StackLayout>  
  7.     </ContentView>  
  8. </ContentPage> 


Now, add the Frame Control to your label.


MainPage.xaml
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XamarinForms_Frame" x:Class="XamarinForms_Frame.XamarinForms_FramePage">  
  3.     <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />  
  4.     <ContentView>  
  5.         <StackLayout HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">  
  6.             <Frame>  
  7.                 <Label Text="Hello Xamarin Forms."></Label> </Frame>  
  8.         </StackLayout>  
  9.     </ContentView>  
  10. </ContentPage>  
 
 
Step 6

In this step, add the frame control to Button.

 
MainPage.xaml
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XamarinForms_Frame" x:Class="XamarinForms_Frame.XamarinForms_FramePage">  
  3.     <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />  
  4.     <ContentView>  
  5.         <StackLayout HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">  
  6.             <Frame>  
  7.                 <Button HeightRequest="20" WidthRequest="200" Text="Click Me."></Button> </Frame>  
  8.         </StackLayout>  
  9.     </ContentView>  
  10. </ContentPage>  
 
 
Step 7

In this step, create a ListView without any Border Shadow Effect.


MainPage.xaml
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XamarinForms_Frame" x:Class="XamarinForms_Frame.XamarinForms_FramePage">  
  3.     <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />  
  4.     <ContentView>  
  5.         <StackLayout Margin="50" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">  
  6.             <ListView x:Name="lstValue" SeparatorVisibility="None">  
  7.                 <ListView.ItemTemplate>  
  8.                     <DataTemplate>  
  9.                         <ViewCell>  
  10.                             <StackLayout>  
  11.                                 <Label Text="{Binding Title}"></Label> </StackLayout>  
  12.                         </ViewCell>  
  13.                     </DataTemplate>  
  14.                 </ListView.ItemTemplate>  
  15.             </ListView>  
  16.         </StackLayout>  
  17.     </ContentView>  
  18. </ContentPage>  
 
Now, add the Frame Control to your ListView Item for Border Shadow effect.

MainPage.xaml 
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XamarinForms_Frame" x:Class="XamarinForms_Frame.XamarinForms_FramePage">  
  3.     <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />  
  4.     <ContentView>  
  5.         <StackLayout Margin="50" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">  
  6.             <ListView x:Name="lstValue" SeparatorVisibility="None">  
  7.                 <ListView.ItemTemplate>  
  8.                     <DataTemplate>  
  9.                         <ViewCell>  
  10.                             <Frame HasShadow="true">  
  11.                                 <StackLayout>  
  12.                                     <Label Text="{Binding Title}"></Label> </StackLayout>  
  13.                             </Frame>  
  14.                         </ViewCell>  
  15.                     </DataTemplate>  
  16.                 </ListView.ItemTemplate>  
  17.             </ListView>  
  18.         </StackLayout>  
  19.     </ContentView>  
  20. </ContentPage>  
 
 
Now, change the OutlineColor Property in frame.
 
 
 
MainPage.xaml
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XamarinForms_Frame" x:Class="XamarinForms_Frame.XamarinForms_FramePage">  
  3.     <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />  
  4.     <ContentView>  
  5.         <StackLayout Margin="50" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">  
  6.             <ListView x:Name="lstValue" SeparatorVisibility="None">  
  7.                 <ListView.ItemTemplate>  
  8.                     <DataTemplate>  
  9.                         <ViewCell>  
  10.                             <Frame Margin="10,10,10,-10" OutlineColor="Blue" HasShadow="true">  
  11.                                 <StackLayout>  
  12.                                     <Label Text="{Binding Title}"></Label> </StackLayout>  
  13.                             </Frame>  
  14.                         </ViewCell>  
  15.                     </DataTemplate>  
  16.                 </ListView.ItemTemplate>  
  17.             </ListView>  
  18.         </StackLayout>  
  19.     </ContentView>  
  20. </ContentPage>
