 Example of Login and Home component in blazor| working with blazor components. Components in blazor c#

Here's an example of how you can create a login form in Blazor and redirect to a home component after successful login:

1. Create a Login Component:

   Create a new Blazor component named `Login.razor`. This component will contain the login form and handle the login logic.

   razor

   <h3>Login</h3>

   <form @onsubmit="Login">

       <label for="username">Username:</label>

       <input id="username" type="text" @bind="username" />

       <label for="password">Password:</label>

       <input id="password" type="password" @bind="password" />

       <button type="submit">Login</button>

   </form>

   @code {

       private string username;

       private string password;

       private async Task Login()

       {

           // Perform authentication logic here

           // You can validate the username and password against a database or any other authentication mechanism

           // Simulating a successful login

           bool isAuthenticated = true;

           if (isAuthenticated)

           {

               NavigationManager.NavigateTo("/home");

           }

           else

           {

               // Handle authentication failure

           }

       }

   }

   

   In this example, the `Login` method is called when the form is submitted. You can perform your authentication logic inside this method, such as validating the username and password against your authentication mechanism. If the authentication is successful, you can use `NavigationManager.NavigateTo` to redirect to the home component (`/home` in this example).

2. Create a Home Component:

   Create a new Blazor component named `Home.razor`. This component will represent the home page or the main content of your application after successful login.

   razor

   <h3>Welcome to the Home Page!</h3>

   <!-- Add your home page content here -->

   

3. Configure Routes:

   Open the `App.razor` file and configure the routes for the login and home components. By default, the login component will be displayed initially, and after successful login, the home component will be displayed.

   razor

   <Router AppAssembly="@typeof(Program).Assembly">

       <Found Context="routeData">

           <RouteView RouteData="@routeData" DefaultLayout="typeof(MainLayout)" />

       </Found>

       <NotFound>

           <LayoutView Layout="typeof(MainLayout)">

               <p>Sorry, there's nothing at this address.</p>

           </LayoutView>

       </NotFound>

   </Router>

   

4. Start the Application:

   Start your Blazor application, and you should see the login form initially. After entering valid login credentials and clicking the "Login" button, you will be redirected to the home component.

Note that this example only demonstrates the basic login functionality. In a real-world scenario, you would typically integrate a proper authentication mechanism and handle authentication failures appropriately.

By following these steps, you can create a login form in Blazor and redirect to a home component after successful login.
