按钮在asp.net web表单中不触发事件

Question

你能帮我的东西我挣扎了4天，按钮事件不火:(在MasterPage我用它来添加控制

 <Login:UserLogin runat="server" ID="UserLogin"  EnableViewState="false" > </Login:UserLogin>

控件是这个

    <%@ Control Language="C#" AutoEventWireup="true" CodeFile="UserLogin.ascx.cs" Inherits="BookApartmentsPortal.controls.UserLogin"  %>
    <%@ Register TagPrefix="MultiLanguage" Namespace="MultiLanguage.multilanguage" %>

<script type="text/javascript">        
       function DeleteKartItems() {  
                var inputEmail =   $("#ctl00_UserLogin_txtEmailVal").val();
                var user = {
                    email: "s.krastanov",
                    password: "1"
                };

              $.ajax({
               type: "POST",
               url: 'PublicDefault.aspx/Getvalues',
               data: JSON.stringify({ person: user }),
               contentType: "application/json; charset=utf-8",
               dataType: "json",
               success: function (msg) {
                   $("#divResult").html("success");
               },
               error: function (e) {
                   $("#divResult").html("Something Wrong.");
               }
           });
           $("#ctl00_PublicDefault_buttonLog").Click();
   }
</script>--%>

    <h3>

    <form action="/" method="POST" id="formasd">

后端是这样的:

    public partial class UserLogin : System.Web.UI.UserControl
    {

          protected void Page_Load(object sender, EventArgs e)
        {
            if (IsPostBack) 
            {
                this.btnLogon.Click += new System.EventHandler(btnLogon_Click);
                Response.Write("you click");
            }
            this.btnLogon.Click += new System.EventHandler(btnLogon_Click);
            LoginFB.NavigateUrl = "https://www.facebook.com/v2.0/dialog/oauth/?client_id=" + ConfigurationManager.AppSettings["FacebookAppId"] + "&redirect_uri=http://" + ConfigurationManager.AppSettings["URL"].ToString() + "/Publish/UserFB.aspx&response_type=code&state=1";
        }
        override protected void OnInit(EventArgs e)
        {
            InitializeComponent();
            base.OnInit(e);
        }
        private void InitializeComponent()
        {
            //btnLogon.ServerClick += new EventHandler(btnLogon_Click);
            this.btnLogon.Click += new System.EventHandler(btnLogon_Click);
            //btnLogon.ServerClick += new CommandEventHandler(btnLogonClick);
           // btnLogon.Command += btnLogon_Click;
        }

        public void btnLogon_Click(object sender, EventArgs e)
        {
            Label1.Text = "submit button is press";
           // if (LoginSet == false )
           // {
                string Name = txtPassword.Text;
                string Dev = txtEmailVal.Value;
                String[] RemoteAddr = Request.ServerVariables.GetValues("REMOTE_ADDR");
                if (RemoteAddr.Length <= 0)
                    return;
                LoginDB oLoginDb = new LoginDB(txtEmailVal.Value.Trim(), txtPassword.Text.Trim(), true, RemoteAddr[0].ToString());
                oLoginDb.Database = new SQLDatabase(Convert.ToString(ConfigurationManager.ConnectionStrings["dbConnectionString"].ToString()));
                try
                {
                    if (oLoginDb.Authenticate(ConfigurationManager.AppSettings["SecKeyIni"].ToString(), ConfigurationManager.AppSettings["SecKeySec"].ToString()))
                    {
                        Response.Cookies[FormsAuthentication.FormsCookieName].Expires = DateTime.Now;
                        FormsAuthentication.RedirectFromLoginPage(txtEmailVal.Value.Trim(), false);
                        Session["LoginUserName"] = txtEmailVal.Value.Trim();
                     //   _loginSet = true;
                    }
                    else
                    {
                     //   _loginSet = false;
                    }
                }
                catch (Exception Exception)
                {
                    Context.Trace.Warn(Exception.Message);
                    Global.ErrorMessage(Exception.Message, Context);
                 //   _loginSet = false;
                }
            //}
        }
}

这个控件是登录表单，我只是不能从输入框中获取值，因为事件不触发。一个想法是使AJAX post到静态方法，但之后我不能用这个变量做新的会话。我尝试了所有方法，但这个按钮就是不能触发事件。我不知道下一步该做什么，你能帮帮我吗?

好了，又挣扎了一天，我设法绕着小路走了一小圈。在第一步中，我创建了一个按钮来触发事件(javascript函数)并生成cookie，之后我为实际的asp:Button:

创建了click事件。

<script type="text/javascript">        
       function LoginClicked() {  
                var inputEmail =   $("#txtEmail").val();
                var inputPass =   $("#txtPassword").val();
                if(inputEmail != "" && inputPass != ""){
                var userSet = inputEmail + "&" + inputPass;
                setCookie("UserSettings", userSet, 1);
                function setCookie(cname, cvalue, exdays) {
                    var d = new Date();
                    d.setTime(d.getTime() + (exdays*1*60*1000));
                    var expires = "expires=" + d.toGMTString();
                    document.cookie = cname+"="+cvalue+"; "+expires;
                 }
          $("#ctl00_UserLogin_btnLogon").click();
           }
   }
</script>

这里是按钮:

<asp:Panel runat="server" ID="panekl">
            <asp:Button runat="server" ID="btnLogon" UseSubmitBehavior="false" CssClass="no-display" ></asp:Button>
      </asp:Panel>
             <button class="login-btn" id="btnLogon1" name="btnLogon1" onclick="LoginClicked()">
             <i class="fa fa-paper-plane"></i><MultiLanguage:MultiLanguageLiteral ID="MultiLanguageLiteral4" runat="server" Resource="1270" />

在后端，我得到cookie，拆分它，并检查验证:

public void btnLogon_Click()
        {
           if (LoginSet == false )
           {
                string[] txtSome = Request.Cookies["UserSettings"].Value.Split('&');
                if (Request.Cookies["UserSettings"] != null && txtEmailVal != "" && txtPassword != "")
                {
                    txtEmailVal = txtSome[0].Trim();
                    txtPassword = txtSome[1].Trim();
                }
                String[] RemoteAddr = Request.ServerVariables.GetValues("REMOTE_ADDR");
                if (RemoteAddr.Length <= 0)
                    return;
                LoginDB oLoginDb = new LoginDB(txtEmailVal, txtPassword, true, RemoteAddr[0].ToString());
                oLoginDb.Database = new SQLDatabase(Convert.ToString(ConfigurationManager.ConnectionStrings["dbConnectionString"].ToString()));
                try
                {
                    if (oLoginDb.Authenticate(ConfigurationManager.AppSettings["SecKeyIni"].ToString(), ConfigurationManager.AppSettings["SecKeySec"].ToString()))
                    {
                        Session["IdUserLogin"] = txtEmailVal;
                       _loginSet = true;
                       HttpCookie myCookie = new HttpCookie("UserSettings");
                       myCookie.Expires = DateTime.Now.AddDays(-1d);
                       Response.Cookies.Add(myCookie);
                       Label1.Text = "submit button is press";
                    }
                    else
                    {
                       _loginSet = false;
                    }
                }
                catch (Exception Exception)
                {
                    Context.Trace.Warn(Exception.Message);
                    Global.ErrorMessage(Exception.Message, Context);
                 _loginSet = false;
                }
           }
        }

这是我从控件中获取值的唯一方法。
