新添加的按钮在asp中不起作用

Question

我在这里使用的是 Web 表单而不是 MVC，而且我很难找到将 OnClick 绑定到新生成的按钮的方法。我将自己编码到一个角落，我的页面内容是从其后面的代码中添加的，字符串中的 hml

articleHTML += "<asp:Button ID='button' type='button' OnClick='Pull_Click' class='btn btn-default btn- lg'>Pull</asp:button>";

protected void Pull_Click(object sender, EventArgs e)  {
        LabelTest.Text = "Works";  
} 

点击按钮时不会调用Pull_Cick。我猜我需要直接在模板中循环浏览我的内容？谢谢！

您添加按钮的方式不正确，请检查

点击事件

 Button btn = new Button();
 btn.Text = "test";
 btn.Click += btn_Click;   
 maindiv.Controls.Add(btn);

 void btn_Click(object sender, EventArgs e)
    {
        throw new NotImplementedException();
    }

让按钮调用ajax

        Button btn = new Button();
        btn.Text = "test";
        btn.OnClientClick = "newbtn_Click()";


    [WebMethod]
    public static string newbtnSubmit(string name)
    {
        return name;
    }

并在 JavaScript 中添加

 <script>
    function newbtn_Click()
    {
        var dataValue = { "name": "my name"};
        $.ajax({
            type: "POST",
            url: "Default.aspx/newbtnSubmit",
            data: dataValue,
            error: function (XMLHttpRequest, textStatus, errorThrown) {
                alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
            },
            complete: function (jqXHR, status) {
                alert("complete: " + status + "\n\nResponse: " + jqXHR.responseText);
            }
        });
    }
 </script>
