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

The lecture explains the 'should render' method, which controls UI rendering based on a boolean value. The method is demonstrated through a Visual Studio example, where UI refresh is toggled using buttons. The code setup involves creating a Razor component, defining variables and methods, and implementing logic to control rendering. The application is then run to observe how UI updates are managed.

What does the 'should render' method return?

• A boolean value

• A string value

• A float value

• An integer value

What happens if the 'should render' method returns true?

• The UI becomes static

• The UI crashes

• The UI is re-rendered

• The UI is not rendered

What is the purpose of the 'turn off' method in the example code?

• To change the message

• To set 'should render' to false

• To initialize the component

• To increment the counter

What is the initial value of the 'should render' boolean in the code?

• False

• Null

• True

• Undefined

What does the 'change message' method do?

• It resets the counter

• It turns off the UI refresh

• It initializes the component

• It changes the message based on the counter

What is string interpolation used for in the code?

• To evaluate variables within strings

• To concatenate strings

• To create arrays

• To format numbers

What happens when the 'turn on' button is clicked?

• The message is reset

• The UI refresh is turned off

• The UI refresh is turned on

• The application crashes

What is the role of the 'should render' method in the final application demonstration?

• To initialize the application

• To log user interactions

• To control the UI refresh based on button clicks

• To change the button colors

How does the application behave when the 'turn off' button is clicked?

• The message changes automatically

• The UI stops refreshing

• The UI refreshes continuously

• The application restarts

What is demonstrated by clicking the 'message change' button multiple times?

• The message updates with the counter

• The message remains static

• The UI crashes
