How can I change the value in EditForm by code?

Here is the html:

<EditForm Model="Input" method="post" OnValidSubmit="LoginUser" FormName="login" Enhance><DataAnnotationsValidator /><div id="SubmitDiv"><InputText @bind-Value="Input.Email" class="ant-input SubmitContentInput" autocomplete="username" aria-required="true" placeholder="@_Localizer["ErrorMessageUserNameRequire"]" /><ValidationMessage For="() => Input.Email" class="ant-form-item-explain-error" /><InputText @bind-Value="Input.Password" type="password" class="ant-input SubmitContentInput" autocomplete="current-password" aria-required="true" placeholder="@_Localizer["ErrorMessagePasswordRequire"]" /><ValidationMessage For="() => Input.Password" class="ant-form-item-explain-error" /></div>     </EditForm>

And here is the model:

  [SupplyParameterFromForm]  private InputModel Input { get; set; } = new(); private sealed class InputModel {             [EmailAddress(ErrorMessageResourceName = "ErrorMessageEMailVerify", ErrorMessageResourceType = typeof(TuskyPhoenix.Resources.Components.Account.Pages.Login))]     [Required(ErrorMessageResourceName = "ErrorMessageUserNameRequire", ErrorMessageResourceType = typeof(TuskyPhoenix.Resources.Components.Account.Pages.Login))]     public string Email { get; set; } = "";     [Required(ErrorMessageResourceName = "ErrorMessagePasswordRequire", ErrorMessageResourceType = typeof(TuskyPhoenix.Resources.Components.Account.Pages.Login))]     [DataType(DataType.Password)]     public string Password { get; set; } = ""; }

And here is the code to set the value:

protected override async Task OnAfterRenderAsync(bool firstRender){    if (firstRender)    {        var _uriBuilder = new UriBuilder(_NavigationManager.Uri);        var _query = System.Web.HttpUtility.ParseQueryString(_uriBuilder.Query);        var _result = _query["UserName"];        if (_result is { })        {            Input.Email = _result;        }    }}

When the user input the URL "https://localhost:1434/Account/login?UserName=abc@Gmail.com"

It can get the query parameter abc@Gmail.com successfully.

However, after setting the value of Input.Email to the query parameter, the UI doesn't change any.

What I actually want to do is to input the email by URL.

What's wrong with my code? Is it only a one-way binding? How can I implement this?
