Membership.Updateuser ne met pas vraiment à jour la base de données

Question

Je travaille actuellement sur un système d'adhésion pour mon application web, qui est basé sur l'authentification par formulaires du framework.

J'ai créé quelques utilisateurs avec l'outil intégré, et la connexion fonctionne parfaitement. Mais maintenant, ce que je veux faire est de donner à l'administrateur la possibilité de créer, modifier, supprimer des utilisateurs.

Voici donc ce que j'ai en ce moment:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    Dim muc As MembershipUserCollection = Membership.GetAllUsers() 

    ComboBox1.DataSource = muc 
    ComboBox1.DataValueField = "UserName" 
    ComboBox1.DataTextField = "UserName" 
    ComboBox1.DataBind() 
End Sub 

Protected Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ComboBox1.SelectedIndexChanged 

    Dim userName As String = ComboBox1.SelectedValue 

    Dim mu As MembershipUser = Membership.GetUser(userName) 

    Dim userRoles As String() = Roles.GetRolesForUser(userName) 

    tbComments.Text = mu.Comment 
    tbEmail.Text = mu.Email 
    lblUserName.Text = mu.UserName 
End Sub 

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click 
    Dim userName As String = ComboBox1.SelectedValue 
    Dim mu As MembershipUser = Membership.GetUser(userName) 

    If Not mu Is Nothing Then 
     Try 
      mu.Comment = tbComments.Text 
      Membership.UpdateUser(mu) 

      mu.Email = tbEmail.Text 
      Membership.UpdateUser(mu) 

      mu.IsApproved = True 
      Membership.UpdateUser(mu) 

      mu = Nothing 
     Catch ex As Exception 
      Console.WriteLine(ex.ToString()) 
     End Try 
    End If 

    DetailPanel.Visible = False 
End Sub 

Le problème est que le dossier ne semble pas être mis à jour dans la base de données. J'ai fait les appels multiples à Membership.UpdateUser après avoir lu this blog entry, mais cela n'a rien changé.

Chose étrange, j'ai remarqué pendant le débogage, est que lorsque j'entre la méthode Button1_Click, Membership.GetUser(userName) me renvoie des valeurs de ma tentative de précédent! Je ne comprends pas vraiment ce qui me manque.

Quelqu'un a une idée?

Merci d'avance!

Première:

L'entrée de blog que vous citez est juste mal.

Voici la méthode que vous appelez, dites-moi si vous voyez une indication qu'il doit être appelé plusieurs fois pour mettre à jour des propriétés multiples:

public override void UpdateUser(MembershipUser user) 
{ 
    if (user == null) 
    { 
     throw new ArgumentNullException("user"); 
    } 
    SecUtility.CheckParameter(ref user.UserName, true, true, true, 0x100, "UserName"); 
    string email = user.Email; 
    SecUtility.CheckParameter(ref email, this.RequiresUniqueEmail, this.RequiresUniqueEmail, false, 0x100, "Email"); 
    user.Email = email; 
    try 
    { 
     SqlConnectionHolder connection = null; 
     try 
     { 
      connection = SqlConnectionHelper.GetConnection(this._sqlConnectionString, true); 
      this.CheckSchemaVersion(connection.Connection); 
      SqlCommand command = new SqlCommand("dbo.aspnet_Membership_UpdateUser", connection.Connection); 
      command.CommandTimeout = this.CommandTimeout; 
      command.CommandType = CommandType.StoredProcedure; 
      command.Parameters.Add(this.CreateInputParam("@ApplicationName", SqlDbType.NVarChar, this.ApplicationName)); 
      command.Parameters.Add(this.CreateInputParam("@UserName", SqlDbType.NVarChar, user.UserName)); 
      command.Parameters.Add(this.CreateInputParam("@Email", SqlDbType.NVarChar, user.Email)); 
      command.Parameters.Add(this.CreateInputParam("@Comment", SqlDbType.NText, user.Comment)); 
      command.Parameters.Add(this.CreateInputParam("@IsApproved", SqlDbType.Bit, user.IsApproved ? 1 : 0)); 
      command.Parameters.Add(this.CreateInputParam("@LastLoginDate", SqlDbType.DateTime, user.LastLoginDate.ToUniversalTime())); 
      command.Parameters.Add(this.CreateInputParam("@LastActivityDate", SqlDbType.DateTime, user.LastActivityDate.ToUniversalTime())); 
      command.Parameters.Add(this.CreateInputParam("@UniqueEmail", SqlDbType.Int, this.RequiresUniqueEmail ? 1 : 0)); 
      command.Parameters.Add(this.CreateInputParam("@CurrentTimeUtc", SqlDbType.DateTime, DateTime.UtcNow)); 
      SqlParameter parameter = new SqlParameter("@ReturnValue", SqlDbType.Int); 
      parameter.Direction = ParameterDirection.ReturnValue; 
      command.Parameters.Add(parameter); 
      command.ExecuteNonQuery(); 
      int status = (parameter.Value != null) ? ((int) parameter.Value) : -1; 
      if (status != 0) 
      { 
       throw new ProviderException(this.GetExceptionText(status)); 
      } 
     } 
     finally 
     { 
      if (connection != null) 
      { 
       connection.Close(); 
       connection = null; 
      } 
     } 
    } 
    catch 
    { 
     throw; 
    } 
} 

Deuxième:

Vous reconsolidation votre liste chaque publication. Cela doit être fait une seule fois et la liste est stockée dans viewstate.

Voici une implémentation fonctionnelle:

UpdateUser.aspx

<%@ Page Language="vb" %> 

<script runat="server"> 

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 

     ' be sure that DropDownList1.AutoPostBack = true 

     If Not IsPostBack Then 
      BindUserList() 
     End If 
    End Sub 


    Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ComboBox1.SelectedIndexChanged 
     DisplayDetails(ComboBox1.SelectedValue) 
    End Sub 


    Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click 
     Dim approved As Boolean = True 
     Dim username As String = ComboBox1.SelectedValue 
     Dim comments As String = tbComments.Text 
     Dim email As String = tbEmail.Text 

     UpdateUser(username, approved, comments, email) 
    End Sub 

    Private Sub BindUserList() 
     '' you only need to databind once, the datasource is stored in viewstate 
     Dim muc As MembershipUserCollection = Membership.GetAllUsers() 

     ComboBox1.DataSource = muc 
     ComboBox1.DataValueField = "UserName" 
     ComboBox1.DataTextField = "UserName" 
     ComboBox1.DataBind() 
     '' initialize the selection 
     ComboBox1_SelectedIndexChanged(ComboBox1, EventArgs.Empty) 
    End Sub 


    Private Sub DisplayDetails(ByVal userName As String) 
     Dim mu As MembershipUser = Membership.GetUser(userName) 

     Dim userRoles As String() = Roles.GetRolesForUser(userName) 

     tbComments.Text = mu.Comment 
     tbEmail.Text = mu.Email 
     lblUserName.Text = mu.UserName 
    End Sub 

    Private Sub UpdateUser(ByVal userName As String, ByVal approved As Boolean, ByVal comments As String, ByVal email As String) 
     Dim mu As MembershipUser = Membership.GetUser(userName) 
     If Not mu Is Nothing Then 
      Try 

       mu.Comment = comments 
       mu.Email = email 
       mu.IsApproved = approved 

       Membership.UpdateUser(mu) 

       ErrLabel.Text = "" 
      Catch ex As Exception 
       ErrLabel.Text = ex.Message 
      End Try 
     End If 
    End Sub 
</script>
