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

This video tutorial covers the implementation of lifecycle methods in Visual Studio Code, focusing on 'on parameter set' and 'on parameter set async'. It demonstrates creating a child component, initializing parameters, and building a parent component. The tutorial concludes with running the application and observing the effects of delays in parameter set calls.

What is the primary purpose of the 'on parameter set' method in a component's lifecycle?

• To execute after all parameters are assigned

• To initialize the component's state

• To handle user input events

• To render the component's UI

Which class is used to create a table with borders in the child component?

• table-dark

• table-striped

• table-hover

• table-bordered

What is the initial value set for the 'number' parameter in the child component?

• 1

• 10

• 100

• 0

What is the purpose of the 'count' variable in the child component?

• To track method calls

• To manage component state

• To store the current number

• To handle user input

What is the significance of setting 'count async' to zero initially?

• To clear the UI

• To initialize the async counter

• To prepare for user input

• To reset the component state

Which method is used to introduce a delay in the 'on parameter set async' method?

• Thread.Sleep

• Task.Delay

• System.Wait

• Async.Delay

What is the role of the 'number generator' component in the application?

• To generate random numbers

• To serve as the parent component

• To handle user input

• To display the application's UI

What happens when the 'generate number' button is clicked in the application?

• The application refreshes

• A new number is generated

• The number is incremented

• The application closes

How does the 'on parameter set async' method affect the component when a delay is introduced?

• It speeds up the component's refresh

• It causes an error in the component

• It delays the component's refresh

• It has no effect on the component

What is the effect of calling 'on parameter set' and 'on parameter set async' simultaneously?

• They are ignored

• They execute simultaneously

• They execute in sequence

• They cause a conflict
