使用GridView的RowCommand使用ASP.NET標識刪除和編輯用戶？

Question

我有一個GridView，它通過SqlDataSource綁定到AspNetUsers。我正在嘗試執行GridView_RowCommand以刪除和編輯/更新用戶，但我無法弄清楚如何通過ASP.NET身份API執行此操作。我已將IdentityUser擴展爲名爲ApplicationUser的類，我的數據庫上下文名爲ApplicationDBContext。
當我單擊刪除或編輯GridView行時，如何刪除或更新給定選定用戶的用戶。

這是我到目前爲止，但其基本沒什麼：

protected void Users_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 
     if (e.CommandName == "Delete") 
     { 
      //How do I delete? 

     } 
     else if(e.CommandName == "Edit") 
     { 
      How do I Update? 
     } 
    }

這裏是我放在一起，我沒有的Visual Studio所以它可能不是100％的例子，但它是足夠接近你的目的，我會說：

protected void Users_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "Delete") 
    { 
     int id = Convert.ToInt32(Users.DataKeys[e.RowIndex].Value); 
     ApplicationUser user = (ApplicationUser)IdentityManager.Store.Users.FindAsync(id, CancellationToken.None); 
     using (ApplicationDbContext dbcontext = new ApplicationDbContext()) 
     { 
      dbcontext.UserLogins.RemoveRange(dbcontext.UserLogins.Where(ul => ul.UserId == user.Id)); 
      dbcontext.UserRoles.RemoveRange(dbcontext.UserRoles.Where(ur => ur.UserId == user.Id)); 
      dbcontext.UserSecrets.RemoveRange(dbcontext.UserSecrets.Where(us => us.UserName == user.UserName)); 
      dbcontext.UserManagement.RemoveRange(dbcontext.UserManagement.Where(um => um.UserId == user.Id)); 
      dbcontext.Users.Remove(dbcontext.Users.Where(usr => usr.Id == user.Id).Single()); 
      dbcontext.SaveChanges(); 
     } 
    } 
}

起初，我試圖在GridView的RowCommand其被解僱了，但後來我剛剛結束了對指定在SqlDataSource中的DeleteCommand和更新命令，並且解決了這個問題。

當我配置它產生下面的標記這反過來又使事情工作的SqlDataSource唯一的改動是：

<asp:SqlDataSource ID="UsersSqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" 
        SelectCommand="SELECT [Id], [UserName], [FirstName], [LastName], [Email] FROM [AspNetUsers]" 
        DeleteCommand="DELETE FROM [AspNetUsers] WHERE [Id] = @Id" 
        InsertCommand="INSERT INTO [AspNetUsers] ([Id], [UserName], [FirstName], [LastName], [Email]) VALUES (@Id, @UserName, @FirstName, @LastName, @Email)" 
        UpdateCommand="UPDATE [AspNetUsers] SET [UserName] = @UserName, [FirstName] = @FirstName, [LastName] = @LastName, [Email] = @Email WHERE [Id] = @Id"> 
        <DeleteParameters> 
         <asp:Parameter Name="Id" Type="String" /> 
        </DeleteParameters> 
        <InsertParameters> 
         <asp:Parameter Name="Id" Type="String" /> 
         <asp:Parameter Name="UserName" Type="String" /> 
         <asp:Parameter Name="FirstName" Type="String" /> 
         <asp:Parameter Name="LastName" Type="String" /> 
         <asp:Parameter Name="Email" Type="String" /> 
        </InsertParameters> 
        <UpdateParameters> 
         <asp:Parameter Name="UserName" Type="String" /> 
         <asp:Parameter Name="FirstName" Type="String" /> 
         <asp:Parameter Name="LastName" Type="String" /> 
         <asp:Parameter Name="Email" Type="String" /> 
         <asp:Parameter Name="Id" Type="String" /> 
        </UpdateParameters> 
       </asp:SqlDataSource>
