Hello,

Welcome to Microsoft Q&A!

Firstly take a look at Bindable Layouts in Xamarin.Forms .

Bindable layouts enable any layout class that derives from the Layout<T> class to generate its content by binding to a collection of items .

BindableLayout exposes the attached properties (including ItemsSource ,ItemTemplate) .

The usage is pretty simple

   <StackLayout BindableLayout.ItemsSource="{Binding User.TopFollowers}"  
                Orientation="Horizontal"  
                ...>  
       <BindableLayout.ItemTemplate>  
           <DataTemplate>  
               <controls:CircleImage Source="{Binding}"  
                                     Aspect="AspectFill"  
                                     WidthRequest="44"  
                                     HeightRequest="44"  
                                     ... />  
           </DataTemplate>  
       </BindableLayout.ItemTemplate>  
   </StackLayout>  

Note : While it's technically possible to attach a bindable layout to any layout class that derives from the Layout<T> class, it's not always practical to do so, particularly for the AbsoluteLayout, Grid, and RelativeLayout classes.
