Lifecycle of Blazor Components Blazor components have a lifecycle that defines the various stages a component goes through from its creation to its disposal. Understanding the component lifecycle is crucial for managing state, optimizing performance, and responding to events. Here's an overview of the Blazor component lifecycle events along with sample code to illustrate each stage: Initialization : This is the initial stage where the component's parameters and dependencies are set. It happens before rendering. @code { [Parameter] public string Message { get ; set ; } protected override void OnInitialized ( ) { // Initialization logic } } <h3>@Message</h3> Initialize a database connection Load data from a server Set up bindings Create timers or other asynchronous tasks Parameter Set : This stage occurs when component parameters are set. It can be useful for reacting to changes in parameters. @code { [Parameter] publ
Step-by-Step Guide to Achieving Async Flows in Blazor: 1. Understanding Asynchronous Programming: Before delving into Blazor-specific async flows, it's crucial to understand asynchronous programming concepts like async and await . Asynchronous operations help improve the responsiveness of your UI by not blocking the main thread. 2. Blazor Component Lifecycle: Blazor components have their lifecycle methods. The OnInitializedAsync , OnParametersSetAsync , and OnAfterRenderAsync methods allow you to implement asynchronous operations during various stages of a component's lifecycle. 3. Asynchronous API Calls: Performing asynchronous API calls is a common scenario in web applications. You can use HttpClient to make HTTP requests asynchronously. For example, fetching data from a remote server: @page "/fetchdata" @inject HttpClient Http @ if (forecasts == null ) { <p> < em > Loading... </ em > </ p > } else { <table>
