魔法码?! - .aspx字段缺失&从源代码中消失

标签: visual-studio forms asp.net field

我有一个非常奇怪的&我正在处理的.ASPX页面上的某些表单元素的奇怪问题...页面表单上有一个隐藏的幻灯片,点击一个div,允许用户“预订”。

用于动画幻灯片的jQuery工作正常,点击勾选复选框(id =“rescheck”)就会发生。

问题是,在点击复选框时显示隐藏div中包含的所有字段,并因此滑入视图及其标签,只显示一个文本字段输入,而不显示任何其他内容。检查源代码显示这些丢失的标签和&字段甚至不在源代码中,在MS Visual Studio 2008中查看(和编辑)时,它们位于页面代码中。

正如您所看到的,字段及其标签似乎只是在浏览器中消失了!我不知道是什么引起了这种情况,我不确定下一步该怎么做。

这是我的PAGE代码,来自Visual Studio:

<fieldset id="resreq">
<legend>Make a Reservation?</legend>
    <label for="rescheck" class="rescheck">If you would like to reserve a table     at Madrasi check here:</label>
    <input id="rescheck" type="checkbox" class="rescheck" runat="server" />            

    <div id="reservationfields">
        <div id="res_when">
        <div>
            <asp:Label ID="lblDate" runat="server" AssociatedControlID="txtDate">On which date would you like us to reserve your table?</asp:Label>
               <asp:TextBox ID="txtDate" runat="server" CssClass="res_date" />                   
            </div>
            <div>
                <asp:Label ID="lblTime" runat="server">and for what time?</asp:Label>
                <asp:TextBox ID="txtTime" runat="server" CssClass="res_time" />                  
         </div>                    
        </div><!-- close res_when -->
        <div> 
            <asp:Label ID="lblBranch" runat="server">At which restaurant would you like to make your reservation?</asp:Label>
            <asp:DropDownList ID="ddlBranch" runat="server">
                <asp:ListItem Text="Select a Restaurant" Value="" />
                <asp:ListItem Text="Restaurant 1" Value="Restaurant 1" />
                <asp:ListItem Text="Restaurant 2" Value="Restaurant 2" />
            </asp:DropDownList>
        </div>
        <div>
            <asp:Label ID="lblPeople" runat="server" AssociatedControlID="txtPeople" Text="Number of Guests:" />
            <asp:TextBox ID="txtPeople" runat="server" />  
        </div>
        <div>
            <asp:Label ID="lblDOB" runat="server" AssociatedControlID="txtDOB">Date of Birth:</asp:Label>
            <asp:TextBox ID="txtDOB" runat="server" />                   
        </div>
    </div><!-- close reservation fields -->
</fieldset>

...当您在浏览器中查看“来源”时,这是源代码:

    <fieldset id="resreq">

    <legend>Make a Reservation?</legend>

        <label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label>

        <input name="ctl00$cpcMain$rescheck" type="checkbox" id="ctl00_cpcMain_rescheck" class="rescheck" />        

        <div id="reservationfields">

         <div id="res_when">

          <div>



                 <input name="ctl00$cpcMain$txtDate" type="text" id="ctl00_cpcMain_txtDate" class="res_date" />                   

             </div>

             <div>





 </div>                    

          </div>

            <div> 





            </div>

            <div>





            </div>

            <div>





                <span id="ctl00_cpcMain_rvDOB" style="color:Red;visibility:hidden;">You have entered your Date of Birth incorrectly (dd/mm/yyyy).</span>

            </div>
            </div><!-- close reservation fields -->
    </fieldset>

代码隐藏中是否有任何内容将任何控件的 Visible 属性设置为false?这导致控件根本不在HTML中呈现,而不是将它们置于不可见的状态,这可能会让人很困惑,因为许多人不会期望这样。
