Question

我的问题是每当我点击按钮时，在点击事件上调用按钮后重新加载空页面。该页面仅包含以下代码

    <html>
      <head></head>
      <body>2015</body>
    </html>

我想要做的是显示表单已提交的消息或重定向到其他页面。 Response.Direct和Server.Transfer无法正常工作，我厌倦了将表单包装在一个面板中并创建一个不同的面板，在提交表单后设置为可见，如this示例但是没有每次我点击页面重新加载的按钮时都会解决问题，如上面的代码所示。我不能使用OnClientclick="return false;"，因为我希望调用我的onClick事件。这是我的一些表单代码（按钮的ID是btnSumbitSurvey）：

        <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <div id="wrapper">
          <div id="page-wrapper">
            <div class="wrapper-content" runat="server" >
              <div runat="server" id="SelectLang">                   
                <asp:Label ID="lblLanguage" runat="server" CssClass="select-lang" style="text-align: center;" Text="Select Survey Language | اختر لغة الاستبيان"></asp:Label>
                <asp:RadioButtonList  ID="rblLanguage" OnSelectedIndexChanged="ddlSelectedIndexChanged"  runat="server" AutoPostBack="True" >
                </asp:RadioButtonList>
              </div>
            <div ID="details" class="survey-details" runat="server" Visible="False">
               <span runat="server" class="name" ID="SurveyName"></span>
               <p runat="server" class="desc" ID="SurveyDescription"></p>
               <div runat="server" id="questionsList" >
                 <asp:Repeater ID="rptQuestionsEng" runat="server" Visible="False" OnItemDataBound="rpt_ItemDataBound" >                                
                    <ItemTemplate>
                      <div class="question">
                        <asp:HiddenField ID="hide" Value='<%# Bind("QuestionId") %>' runat="server" />
                        <asp:Label runat="server" ID="lblQuestion" Text='<%# Bind("QuestionEng") %>' CssClass="questionLabel"></asp:Label>
                        <asp:RequiredFieldValidator ID="rfvEng" runat="server" ErrorMessage="*" Display="Dynamic" ControlToValidate="rblQuestionEng" ForeColor="red" ></asp:RequiredFieldValidator>      
                        <asp:RadioButtonList runat="server" ID="rblQuestionEng">                           
                        </asp:RadioButtonList>      
                      </div>
                   </ItemTemplate>
                  </asp:Repeater>
                 </div>
                 <asp:Button ID="btnSumbitSurvey" runat="server" Text="Submit" OnClick="btnSubmitSurvey_Click" Visible="False" class="btn"/>
                 </div>
                </div>
               </div>
              </div>
            </form>

代码背后：

     protected void btnSubmitSurvey_Click(object sender, EventArgs e)
      {
       if (rblLanguage.SelectedValue.Equals("1"))
         {
            List<Response> responsesList = new List<Response>();
            foreach (RepeaterItem item in rptQuestionsEng.Items)
            {
                Response response = new Response();

                if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
                {
                    var rbl = (RadioButtonList)item.FindControl("rblQuestionEng");

                    if (!string.IsNullOrEmpty(rbl.SelectedValue))
                    {
                        answerId = Convert.ToInt32(rbl.SelectedValue);
                        response.QuestionResponse = rbl.SelectedItem.Text;
                        response.ResponseDate = DateTime.Now;
                        response.SurveyId = _surveyId;
                        response.PateintSurveyId = _patientSurveyId;
                    }                        
                }
                var hide = item.FindControl("hide") as HiddenField;
                var id = hide.Value;
                int questionId = Convert.ToInt32(id);

                response.QuestionAnswerId = _blSurvey.GetQuestionAnswer(questionId, answerId);
                responsesList.Add(response);                   
            }

        if (_blResponse.AddResponse(responsesList))
        {
            Response.Redirect(Enums.ReferenceLinks.PostSubmission + "?E=F", true);
            //postPanel.Visible = true;
            //prePanel.Visible = false;
            //SubmitMsg.InnerHtml = "Thank you for participating, your submission has been received";
        }
      }
    }

Answer 1

确保您已检查过IsPostBack -

if (!IsPostBack)
{
    // load defaults, language list, repeater etc.
}

我猜您没有使用它，因此每次发布表单时都会加载默认设置并且条件不符合。

我花了好几个小时试图找出问题所在。最后，我删除了我页面中的所有javascript代码，特别是我在页脚中的代码，并且它有效。

按钮单击正在重新加载空白页面
