We have a login
If you type the username and password and press submit, we called the login.cs
everything is validate and OK,
but we have a password recovery link, where you have to type the username in order
to send you the email, in both case we called the same page: login, but we a parameter: <a href="login?expire=1" class="btn btn-ic btn-link pkg-photo">Olvide mi clave</a>
this is the function called:
if (Get<bool>("expire"))
	{
   	   if (!Empty(Username))
	   {
		ExecuteRow("sp_sopv2_EnviarCorreoClave " + Username);
   	        SuccessMessage = "Se a enviado un correo a su cuenta de email que tiene registrado con nosotros favor verificar.Una vez acceda a su cuenta debe cambiar su clave por seguridad";
  	 }
	else{
		WarningMessage = "Favor de escribir el Usuario!";
	   }
}

the problem: the username field it passed with no value, only has value if you press submit

Here de login.cshtml:

 <div class="box box-primary login-box ewLoginBox">
    <div class="login-box-body">
	<p class="login-box-msg">@Html.Raw(Language.Phrase("Login"))</p>

    <div class="form-group">

	     }
	  </div>
	}
<a href="login?expire=1" class="btn btn-ic btn-link pkg-photo">Olvide mi clave</a>


Here the login.cs 
Username = ""; // Initialize  
string password = "";
if (IsLoggingIn()) { // After changing password
   Username = Session.GetString(Config.SessionUserProfileUserName);
   password = Session.GetString(Config.SessionUserProfilePassword);

   validPassword = Security.ValidateUser(ref Username, ref password, false);
   if (validPassword) {
	Session[Config.SessionUserProfileUserName] = "";
	Session[Config.SessionUserProfilePassword] = "";
   }
   } else { // Normal login
	if (!Security.IsLoggedIn)
	Security.AutoLogin();
	Security.LoadUserLevel(); // Load user level
	bool encrypted = false;					
	if (!Empty(Post("username"))) {
  	// Login by form post
	Username = RemoveXss(Post("username"));
	password = RemoveXss(Post("password"));
	LoginType = RemoveXss(Post("type"));
        .
        .
	.
	
	if (Get<bool>("expire"))
	{
   	   if (!Empty(Username))
	   {
		ExecuteRow("sp_sopv2_EnviarCorreoClave " + Username);
   	        SuccessMessage = "Se a enviado un correo a su cuenta de email que tiene registrado con nosotros favor verificar.Una vez acceda a su cuenta debe cambiar su clave por seguridad";
