在服务器上发布时不调用后面的用户控制代码

Question

我有一个简单的用户控件，它基本上是一个联系表单，由三个文本框、1 个按钮和 1 个标签组成。我也在使用 Telerik RadAjaxLoadingPanel 和 RadAjaxPanel。用户控件的标记如下，

<telerik:RadAjaxLoadingPanel ID="RALP_ContactForm" runat="server" Transparency="5">
    <div class="border" style="display: table; height: 240px; width: 240px; #position: relative;
        overflow: hidden; background-color:White">
        <div class="border" style="#position: absolute; #top: 50%; display: table-cell; text-align: center;
            vertical-align: middle;">
            <div class="border" style="width: 100%; #position: relative; #top: -50%">
                <img src="images/cf_animation.GIF" alt="Processing Request..." />
            </div>
        </div>
        </div>
</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel ID="upContactForm" runat="server">
    <div id="form-main">
        <div id="form-div">
            <p class="name">
                <asp:TextBox ID="txtContactName" ValidationGroup="ContactForm" CausesValidation="true"
                    runat="server" name="name" CssClass="validate[required,custom[onlyLetter],length[0,100]] feedback-input"
                    ClientIDMode="Static" placeholder="Name"></asp:TextBox>
                <asp:CustomValidator ID="customValidator" runat="server" ValidationGroup="ContactForm"
                    ControlToValidate="txtContactName" Display="Dynamic" ClientValidationFunction="ValidateContactName"
                    ErrorMessage="" ValidateEmptyText="true"></asp:CustomValidator>
            </p>
            <p class="email">
                <asp:TextBox ID="txtContactEmail" ValidationGroup="ContactForm" CausesValidation="true"
                    runat="server" name="email" CssClass="validate[required,custom[onlyLetter],length[0,100]] feedback-input"
                    ClientIDMode="Static" placeholder="Email"></asp:TextBox>
                <asp:CustomValidator ID="customValidator1" runat="server" ValidationGroup="ContactForm"
                    ControlToValidate="txtContactEmail" Display="Dynamic" ClientValidationFunction="ValidateContactEmail"
                    ErrorMessage="" ValidateEmptyText="true"></asp:CustomValidator>
            </p>
            <p class="text">
                <asp:TextBox ID="txtContactComment" ValidationGroup="ContactForm" CausesValidation="true"
                    TextMode="MultiLine" runat="server" name="text" ClientIDMode="Static" CssClass="validate[required,custom[onlyLetter],length[0,100]] feedback-input"
                    placeholder="Comment"></asp:TextBox>
                <asp:CustomValidator ID="customValidator2" runat="server" ValidationGroup="ContactForm"
                    ControlToValidate="txtContactComment" Display="Dynamic" ClientValidationFunction="ValidateContactComment"
                    ErrorMessage="" ValidateEmptyText="true"></asp:CustomValidator>
            </p>
            <p><asp:Label ID="lblMessage" runat="server" Visible="false"></asp:Label></p>
            <div class="submit">
                <asp:Button ID="btnSubmitContactForm" Width="100%" runat="server" ValidationGroup="ContactForm"
                    Text="SEND" CssClass="btn-flat gr btn-submit-reg" OnClick="btnSubmitContactForm_Click" />
            </div>
        </div>
    </div>

在后面的代码中，我只是将文本框中的信息发送到一个电子邮件地址。点击提交按钮时的事件代码如下，

protected void btnSubmitContactForm_Click(object sender, EventArgs e)
    {
        try
        {                
            string AppPath = Request.PhysicalApplicationPath;
            StreamReader sr = new StreamReader(AppPath + "EmailTemplates/UserFeedback.htm");

            string MailBody = sr.ReadToEnd();
            MailBody = MailBody.Replace("<%Name%>", txtContactName.Text.Trim());
            MailBody = MailBody.Replace("<%Email%>", txtContactEmail.Text.Trim());
            MailBody = MailBody.Replace("<%Comments%>", txtContactComment.Text.Trim());

            // Close the StreamReader after reading text from it
            sr.Close();

            MailMessage message = new MailMessage(
                                   "sender@mymail.com",
                                   "receiver@mymail.com",
                                   "Feedback",
                                   MailBody);

            message.IsBodyHtml = true;

            SmtpClient smtp = new SmtpClient();
            smtp.Host = "mail.myserver.com";
            smtp.Port = 25;
            smtp.EnableSsl = false;
            smtp.Credentials = new NetworkCredential("MyUserName", "MyPassword");

            try
            {
                smtp.Send(message);
            }
            catch
            {

            }

            txtContactComment.Text = "";
            txtContactEmail.Text = "";
            txtContactName.Text = "";

            lblMessage.Visible = true;
            lblMessage.ForeColor = System.Drawing.Color.Green;
            lblMessage.Text = "Feedback sent successfully!";

        }
        catch
        {
            lblMessage.Visible = true;
            lblMessage.ForeColor = System.Drawing.Color.Red;
            lblMessage.Text = "Error sending feedback ! ";
        }

    }

User控件是这样调用的，

<uc1:FooterContactForm ID="FooterContactForm" runat="server"></uc1:FooterContactForm>

并且在页面顶部，

<%@ Register Src="ContactForm.ascx" TagName="FooterContactForm" TagPrefix="uc1" %>

现在这一切都变得非常简单，并且在我的测试机上工作得很好。当我在服务器上发布它时，会显示加载图像，但不会触发后面的代码。我试图在用户控件的 Page_Load 事件的标签中设置虚拟文本，但即使是该测试也不会显示在实时服务器上的用户控件上。我每次在本地提交时都会收到电子邮件。

我的问题是，当用户控件发布到实时服务器上时，为什么不调用后面的代码，是否有人遇到过这样的问题？

Answer 1

当你在 ajax 面板中有一些东西，并且由于某种原因开始不起作用时，可能是你错过了一个 javascript 错误，一个未加载的文件，一个异常你没看到。

在这种情况下，只需删除 ajax 面板以定位代码上的错误，and/or 检查浏览器上的 javascript 控制台错误。

从您的意见来看，如果用户未通过身份验证，某些文件夹中的某些 javascript 文件会因安全问题而无法加载，然后您会遇到一些 javascript 错误，无法让您的代码生效运行正确。
