            }
            else if (txtmobile.Text == "")
            {
                ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Please Enter Mobile no')", true);

                 And passing all value from Control to it.
                */
                UserBL objUBL = new UserBL();

                ObjUBO.Name = txtname.Text;

                int result = objUBL.SaveUserregisrationBL(ObjUBO);

                if (result > 0)
                {
                    ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('suceesfully regist :-)')", true);

Answer 1

不知何故，你有复制/粘贴一些代码，你有混合页面，必须有一些主页参考，但没有它。

有两点。

您需要asp:Content才能参考某个母版页

 <asp:Content ID="Content2" ContentPlaceHolderID="ContentSection" runat="server">

但该案例中的代码不能是这样的，您不允许在asp:Content旁边放置html代码...所以如果删除所有asp:Content可能会有效。

其他错误

另一方面，页面包含<form>，而不是asp.net需要的方式。

你混合了一个页面，现在如果充满了bug ......

从一个新页面开始，从visual studio开始构建它 - 不要复制/粘贴其他一些代码......不会那样工作......也许你需要学习asp.net到理解表格必须是什么，它的工作方式以及所有这些，以后再去一些像这样复杂的页面。

表单标记必须类似

<form id="form1" runat="server" >

让您的页面看到内部控件。

web文件的aspx.cs中的bootstrap控件找不到asp app
