Build and Learn ASP.NET 6.0 Blazor Hands-On - Lifecycle Methods (Code Example) - OnInitialized and OnInitializedAsync

The lecture covers the use of 'on initialized' and 'on initialized async' methods in a component. It explains how these methods are triggered when a component is ready and how to use them for asynchronous operations. The tutorial demonstrates setting up a component in Visual Studio, implementing code to change headings based on events, and adding button click functionality. It also covers overriding methods and running the application to see the changes in action.

What is the primary purpose of the OnInitializedAsync method?

• To manage component rendering

• To perform asynchronous operations during component initialization

• To handle component destruction

• To initialize synchronous operations

What is the benefit of adding a navigation menu in the component setup?

• It automatically updates the component's data

• It enhances the component's security

• It improves the component's performance

• It allows for easier access to the component without typing the URL

What is the role of the 'prop' keyword in the code structure?

• To create a new component

• To initialize a local variable

• To define a public property

• To declare a private method

How does the button click event affect the component?

• It resets the component to its initial state

• It triggers a component refresh

• It logs the user out of the application

• It changes the heading and increments a counter

Why is it necessary to override the OnInitialized method?

• To improve the component's loading speed

• To enable automatic updates

• To customize the initialization process for the derived component

• To prevent the base class method from executing

What does the 'await' keyword do in the OnInitializedAsync method?

• It pauses the method execution until the awaited task is complete

• It logs the task completion time

• It cancels the asynchronous operation

• It speeds up the execution of the method

What happens to the heading after the OnInitializedAsync method completes?

• It displays an error message

• It remains unchanged

• It is set to 'Hello from OnInitializedAsync'

• It is cleared
