+# Xamarin Community Toolkit LazyView
+
+The `LazyView` control allows you to delay the initialization of a `View`. You need to provide the type of the `View` that you want to be rendered, using the `x:TypeArguments` XAML namespace attribute, and handle its initialization using the `LoadViewAsync` method. The `IsLoaded` property can be examined to determine when the `LazyView` is loaded.
+
+## Syntax
+
+```xaml
+<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
+             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
+             xmlns:xct="http://xamarin.com/schemas/2020/toolkit"
+             x:Class="MyLittleApp.MainPage"
+             xmlns:local="clr-namespace:Xamarin.CommunityToolkit.Sample.Pages.Views.TabView">
+
+     <StackLayout>
+
+        <xct:LazyView x:TypeArguments="local:LazyTestView" IsLoaded = "{Binding IsLoaded}" />
+
+    </StackLayout>
+
+</ContentPage>
+```
+
+## Properties
+
+|Property  |Type  |Description  |
+|---------|---------|---------|
+| IsLoaded | bool| Gets the loaded status of the `LazyView`. |
+
+## Methods
+
+|Property  |Return Type  |Description  |
+|---------|---------|---------|
+| LoadViewAsync | ValueTask| Initialize the `View`. |
+| Dispose | void | Cleans up the `View`, if required. |
+
