如何为webusercontrol中的超链接a href触发onserverclick服务器事件

Question

我在ASP.NET webusercontrol内有一个html超链接，我将runat服务器属性添加到html超链接，并触发onserverclick事件以从C＃文件背后的代码中处理该事件，但是当事件触发href标记更改为“ javascript：__doPostBack （'controlname $ linkId'，''）并且事件不会触发。

 <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="uc_users.ascx.cs" Inherits="ExtRa.uc_users" %> <div class="panel panel-inverse" style="padding-top: 3%; padding-left: 3%;"> <!-- begin panel-heading --> <div class="uk-grid"> <div class="uk-width-1-1"> <div class="md-card"> <div class="md-card-toolbar"> <div class="md-card-toolbar-actions"> <i class="md-icon material-icons md-card-fullscreen-activate">&#xE5D0;</i> <i class="md-icon material-icons">&#xE5D5;</i> <div class="md-card-dropdown" data-uk-dropdown="{pos:'bottom-left'}"> <i class="md-icon material-icons">&#xE5D4;</i> <div class="uk-dropdown uk-dropdown-small"> <ul class="uk-nav"> <li><a href="#">Action 1</a></li> <li><a href="#">Action 2</a></li> </ul> </div> </div> </div> <h3>المستخدمين </h3> </div> <div class="md-card-content"> <div class="md-card uk-margin-medium-bottom"> <div class="md-card-content"> <div class="uk-overflow-container"> <table id="users_table" <%--class="display"--%> class="uk-table uk-table-nowrap table_check"> <thead> <tr> <th class="uk-width-1-10 uk-text-center">الاكشن</th> <th class="uk-width-1-10 uk-text-center">الصورة</th> <th class="uk-width-1-10 uk-text-center">الاسم</th> <th class="uk-width-1-10 uk-text-center">اسم المستخدم</th> <th class="uk-width-1-10 uk-text-center">الشركة</th> <th class="uk-width-1-10 uk-text-center">تاريخ الانشاء</th> <th class="uk-width-1-10 uk-text-center">المبلغ المسموح التعامل به</th> <th class="uk-width-1-10 uk-text-center">فعال ؟</th> </tr> </thead> <tbody> <% System.Data.DataTable dt = getUsers(); int rowsCount = dt.Rows.Count; int totalPages = rowsCount / 5; foreach (System.Data.DataRow cr in dt.Rows) { string u_id = cr["USER_ID"].ToString(); string u_image = cr["IMAGE"].ToString(); string u_name = cr["USER_NAME"].ToString(); string u_login_name = cr["LOGIN_NAME"].ToString(); string u_company = cr["COMPANY_ID"].ToString(); string u_c_date = cr["CREATE_DATE"].ToString(); string u_max_amount = cr["MAX_AMOUNT"].ToString(); string c_is_active = cr["IS_ACTIVE"].ToString(); string u_is_logged = cr["IS_LOG_IN"].ToString(); %> <tr> <td class="uk-text-center"> <a href="#" id="btn_edit" runat="server" onserverclick="btn_edit_ServerClick"><input type="hidden" id="h_edit" value='<%= u_id %>' runat="server" /><i class="md-icon material-icons">&#xE254;</i></a> <a href="#"><i class="md-icon material-icons">delete</i></a> </td> <td class="uk-text-center"><img class="md-user-image" src='<%="assets/img/user/" + u_image %>' alt=""/></td> <td class="uk-text-center"><%= u_name %></td> <td class="uk-text-center"><%= u_login_name %></td> <td class="uk-text-center"><%= u_company %></td> <td class="uk-text-center"><%= u_c_date %></td> <td class="uk-text-center"><%= u_max_amount + " $" %></td> <td class="uk-text-center"> <% string active_class = "", activ_txt = ""; if (c_is_active == "1") { active_class = "uk-badge uk-badge-success"; activ_txt = "فعال"; } else { active_class = "uk-badge uk-badge-danger"; activ_txt = "غير فعال"; } %> <span class='<%=active_class%>'><%=activ_txt %></span> </td> <td> <% string login_class = "", login_txt = ""; if (u_is_logged == "1") { login_class = "uk-badge uk-badge-defualt"; login_txt = "مسجل دخول"; } else { login_class = "uk-badge uk-badge-warning"; login_txt = "غير مسجل الدخول"; } %> <span class='<%=login_class%>'><%=login_txt %></span> </td> </tr> </tbody> </table> </div> <ul id="com_pages" class="uk-pagination uk-margin-medium-top"> <li class="uk-disabled"><span><i class="uk-icon-angle-double-left"></i></span></li> <li class="uk-active"><span>1</span></li> <li><a href="#" onclick="">2</a></li> <li><a href="#">3</a></li> <li><a href="#">4</a></li> <li><span>&hellip;</span></li> <li><a href="#">10</a></li> <li><a href="#"><i class="uk-icon-angle-double-right"></i></a></li> </ul> </div> </div> </div> </div> </div> </div> <!-- end panel-heading --> </div> 

后面的代码：

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using ExtRa.Data;

namespace ExtRa
{
    public partial class uc_users : System.Web.UI.UserControl
    {
        DataAccess da = new DataAccess();
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        public DataTable getUsers(){ return da.users_get(); }
        protected void btn_delete_ServerClick(object sender, EventArgs e){}
        protected void btn_edit_ServerClick(object sender, EventArgs e)
        {
            Session["action"] = "edit";
            Session["u_a_id"] = h_edit.Value;
        }
    }
}

那么，如何才能从服务器端触发事件？

问题在于“ CausesValidation”

在控件上设置CausesValidation =“ false”，它将从输出的控件中删除javascript: __doPostBack('

在此页面上的某个位置或此输出中包含的某个位置，您可能具有RequiredFieldValidator。 将一个添加到页面后，您将开始获得_doPostBack的内容，因为VS认为应该首先对其进行验证。
