I’m working on a Blazor application and I’m having trouble with my login form. The LoginModel object is always empty when it’s passed to my HandleLogin method, causing the login process to fail. Additionally, I’m encountering the following error:

Severity    Code    Description    Project    File    Line    Suppression State
Error (active)    RZ9991    The attribute names could not be inferred from bind attribute 'bind-Value'. Bind attributes should be of the form 'bind' or 'bind-value' along with their corresponding optional parameters like 'bind-value:event', 'bind:format' etc.

Here is the relevant part of my code:

@inject BTDMiddleware___Frontend.Components.AuthService AuthService

In my HandleLogin method, loginModel.Username and loginModel.Password are always null or empty, even though I have bound them correctly in the form using @bind-Value.

What could be causing the LoginModel object to be empty when the form is submitted, and how can I fix this issue? Additionally, how can I resolve the RZ9991 error regarding the @bind-Value attribute?

Additional Information:

• I’m using Blazor Server.
• The login form is displayed correctly and does not show any validation errors.
• The HandleLogin method is triggered as expected when the form is submitted.
• Any help would be greatly appreciated!

I modified the Blazor login page to handle form input values using local variables instead of directly binding the loginModel. The goal was to avoid binding issues by manually creating the loginModel object during form submission.

**What I Tried:
**

1. Removed the binding of loginModel to the input fields.
2. Introduced local variables username and password to hold the input values.
3. Updated the HandleLogin method to create and populate the loginModel object with these local variables during form submission.

**Expected Outcome:
**I expected the form to accept user inputs for the username and password, store these values in the local variables, and then use these values to create a loginModel object during form submission. This object would be used to send a login request to the server.

**Actual Result:
**The form successfully accepted and stored the input values in the local variables. During form submission, the loginModel was correctly created and populated with these values, and the login request was sent as expected without any binding issues.
