ASP.NET C＃Button OnClick甚至没有触发

Question

我已经筋疲力尽了谷歌，我无法找到解决这个问题的方法。单击.aspx页面上的按钮时，不会从.aspx.cs文件中调用相应的函数。我只是发布我的代码，看看是否有任何接受者。

AddUser.aspx：

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="AddUser.aspx.cs" Inherits="AddUser" %>

<asp:Content ID="tb_AddUserHeader" ContentPlaceHolderID="tb_HeaderPlaceHolder" Runat="Server">
</asp:Content>

<asp:Content ID="tb_AddUserContent" ContentPlaceHolderID="tb_ContentPlaceHolder" Runat="Server">
    <h1>Add User</h1>
    <fieldset>
        <asp:Label ID="tb_lblAddUser_Authorized" runat="server" Visible="false">
            <br />
            <table>
                <tr>
                    <td><u>Username:</u></td>
                    <td><asp:TextBox ID="tb_txtbxUsername" runat="server" Width="200"></asp:TextBox></td>
                </tr>
                <tr>
                    <td><u>Password:</u></td>
                    <td><asp:TextBox ID="tb_txtbxPassword" runat="server" Width="200" TextMode="Password"></asp:TextBox></td>
                </tr>
                <tr>
                    <td><u>Account Type:</u></td>
                    <td><asp:DropDownList ID="tb_ddAccountType" runat="server">
                        <asp:ListItem Value="v" Text="Viewer"></asp:ListItem>
                        <asp:ListItem Value="t" Text="Tester"></asp:ListItem>
                        <asp:ListItem Value="a" Text="Admin"></asp:ListItem>
                        </asp:DropDownList></td>
                </tr>
                <tr>
                    <td><asp:Button ID="tb_btnAddUserSubmit" runat="server" Text="Submit" OnClick="tb_btnAddUserSubmit_Click" UseSubmitBehavior="true" /></td>
                </tr>
            </table>
            <br />
        </asp:Label>

        <asp:Label ID="tb_lblAddUser_Output" runat="server" Visible="false"></asp:Label>

        <asp:Label ID="tb_lblAddUser_Unauthorized" runat="server" Visible="true">
            <br />Only administrators are authorized to view this page
            <br />
            <br />
        </asp:Label>
    </fieldset>
</asp:Content>

和我在文件后面的相应代码，添加User.aspx.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using tbBusinessObjects;
using tbWebClientControllers;

public partial class AddUser : System.Web.UI.Page
{
    tbWebUserController m_userController;

    protected void Page_Load(object sender, EventArgs e)
    {
        m_userController = new tbWebUserController();

        //if (this.IsPostBack)
        //{
        //    String username = tb_txtbxUsername.Text;

        //    //tb_btnAddUser_Click(sender, e);
        //}
        //else
        {
            if (HttpContext.Current.User.Identity.IsAuthenticated)
            {
                FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity;
                FormsAuthenticationTicket ticket = id.Ticket;

                if (ticket.UserData == "a")
                {
                    tb_lblAddUser_Authorized.Visible = true;
                    tb_lblAddUser_Unauthorized.Visible = false;
                }
            }
        }
    }

    protected void tb_btnAddUserSubmit_Click(object sender, EventArgs e)
    {
        tbUser user = new tbUser();
        user.m_username = tb_txtbxUsername.Text;
        user.m_password = tb_txtbxPassword.Text;
        user.m_type = tb_ddAccountType.SelectedValue.ToCharArray()[0];

        if (m_userController.InsertUser(user))
        {
            tb_lblAddUser_Output.Text = "<br />User was successfully added<br /><br />";
        }
        else
        {
            tb_lblAddUser_Output.Text = "<br />There was an error adding user<br /><br />";
        }

        tb_lblAddUser_Output.Visible = true;
        tb_lblAddUser_Authorized.Visible = false;
    }
}

我在Click函数中设置了多个断点，它们从未被击中过。我尝试使用Page.IsPostBack捕获我的Page_Load函数，但是没有数据是从文本框或下拉列表中保存的。

我也尝试在true和false之间更改UseSubmitBehavior标记并完全删除它仍然无法正常工作。我已经从使用按钮事件的其他页面复制/粘贴了尽可能多的代码，但它仍然无效。我完全不知道现在发生了什么。 > _ <

编辑：以防万一它会有任何帮助，这是我的Site.master ...

EDIT2：我将Button移到了我的标签之外，并手动设置了按钮的可见性以及标签的可见性（这是我首先使用这些标签的唯一原因），它运行得很好。我只花了最后一个半小时试图解决这个问题，以防万一其他人再次遇到同样的问题：

ASP：按钮不会从ASP内部消失：标签!!!!!

Answer 1

在页眉中尝试AutoEventWireup =“false”。我在5年内没有在ASP.net工作，但我记得有时会破坏东西。

Answer 2

我在.cs代码后面找不到你的tb_btnAddUserSubmit声明，以及处理程序。

您需要有一个AddUser.Designer.cs类。一定要检查一下。

您还需要在OnInit中注册该事件，而不是Page_load。
