asp.net中的引导数据采集器

我对在我的小项目中编写和尝试bootstrap datepicker还不熟悉。 我在代码中使用了引导日期选择器。它可以很好地选择一个日期并填充到框中，但我不知道如何在codebehind中访问这个日期。 这是我的密码：

    <div class="form-group">
                                          <asp:Label ID="lblDOB" runat="server" CssClass="col-xs-12"  class="form-control" Text="Date Of Birth" Font-Bold="true"></asp:Label>
                                          <div class="row">
                                        <!-- Include Bootstrap Datepicker -->
                                        <link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.3.0/css/datepicker.min.css" />

                                        <script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.3.0/js/bootstrap-datepicker.min.js"></script>

                                    <div class="form-group">

                                     <input type="text" class="form-control" name="date" />
                                       <span class="input-group-addon add-on"><span class="glyphicon glyphicon-calendar"></span></span>

                                      <script>
                                         $(document).ready(function() {
                                         $('#datePicker')
                                         .datepicker({

                                       .on('changeDate', function(e) {
                                       // Revalidate the date field
                                      $('#eventForm').formValidation('revalidateField', 'date');
                                        });

如果我想在我的codebehind中使用电子邮件，那么我会使用txtEmail.text，但我不知道如何在我的codebehind中获取datepicker中的值。我将其与datepicker.text绑定，因为datepicker是给div的id，但它不起作用。

datepicker似乎正在获取存储在以下位置的值：

<input type="text" class="form-control" name="date" />

尝试在其中添加一个runat=“server”属性，然后在代码中使用该Id来获取它

<input type="text" class="form-control" name="date" />
