以前,我有一个包含主用户控件的默认 aspx 页面。

主要的用户控件是用于动态加载菜单项的用户。例如联系人销售订单

当用户点击联系人时,联系人的内容是从其他子用户控件加载的。

在此处输入图像描述

默认 aspx 前端

Here is the aspx page which include the main user control
     <div class="rightColumnModule2">
                                <asp:Panel ID="pnUserControl" runat="server">
                                        <uc2:SubMenuItem ID="MainMenuItem1" runat="server"/>
                                </asp:Panel>
                            </div>

子菜单后端代码

   //dynamic load other content of user control
  //I am using placeholder to load from other user control
        private void loadUserControl()
        {
            if (this.hfSelectSubItemURL.Value != "")
            {
                UserControl ucSimpleControl = LoadControl(this.hfSelectSubItemURL.Value) as UserControl;
                PlaceHolder1.Controls.Add(ucSimpleControl);
            }
        }

ContactPersonList.ascx 前端

div class="rightColumnModule2">


                            <div class="rightColumnModule2TitleContainer">
                                <table class="rightColumnModule2Table">

                                            <div class="rightColumnModule2Title">
                                                Contact Person</div>
                                        </td>

                                        </td>

如何在我的默认 aspx 页面中调用来自 ContactPersonList.ascx 的添加按钮?请指导我一个解决方案。谢谢

你可以有两种方法:

  1. 使用FindControl属性:

     Button btn1 =UserControlID.FindControl("btn1") as Button;
     if(btn1 != null)
     {
       //your stuff with button
     }
    

    或者

  2. 可以直接调用 UserControl 按钮的点击事件:

    用户控制页面:

    <asp:Button ID="btnClick" runat="server" Text="Button1" onclick="btn_Click" />
    

    代码背后:

    public event EventHandler ButtonClick;
    protected void btn_Click(object sender, EventArgs e)
    {
      ButtonClick(sender, e);
    }
    

    页面:

    <UC1:UC1 ID="UserControl1" runat="server" />
    

    后面的代码:

    protected void Page_Load(object sender, EventArgs e)
    {
       UserControl1.ButtonClick += new EventHandler(UserControl1_ButtonClick);
    }
    
    protected void UserControl1_ButtonClick(object sender, EventArgs e)
    {
       Response.Write("this is usercontrol button event.");
    }
