WebForms JQWidgets DatetimePicker

Question

对于任何可以提供帮助的人，我都将jqwidget dateTimeInput日历合并到了Webforms页面上，由于某种原因，该页面未加载基于page_Load函数的代码。它应该将txtStartDate和txtEndDate默认为我用Date静态函数调用的值。如果有人能告诉我我想念的东西，这会有所帮助。我已经调试了后面的代码，并且一切都按我想要的方式工作，但是一旦加载，它就不会呈现在页面上。

服务器页面：

<script type="text/javascript">
    $(document).ready(function () {
        // Create a jqxDateTimeInput
        $("#txtStartDate").jqxDateTimeInput({ width: '105px', height: '38px', template: "success", formatString: 'd' });
        $("#txtEndDate").jqxDateTimeInput({ width: '105px', height: '38px', template: "success", formatString: 'd' });
    });
</script>


                <label style="vertical-align:bottom;">From</label>
                <div id='txtStartDate'>
                </div>

                <label style="vertical-align:bottom;">To</label>
                <div id='txtEndDate'>
                </div>
<asp:CompareValidator id="valCompare" runat="server" ControlToValidate="txtStartDate" ControlToCompare="txtEndDate" Operator="LessThanEqual" Type="Date" ErrorMessage="End Date Must Be Later Than Start Date" Display="dynamic"></asp:CompareValidator>
                <asp:RangeValidator id="valRange" runat="server" ControlToValidate="txtStartDate" Type="Date" ErrorMessage="Search Must Be One Week From Today To Six Months From Today" Display="dynamic">
                </asp:RangeValidator>
                <asp:RangeValidator id="valRange2" runat="server" ControlToValidate="txtEndDate" Type="Date" ErrorMessage="Search Must Be One Week From Today To Six Months From Today" Display="dynamic">
                </asp:RangeValidator>

                txtEndDate.Text = DateTime.Today.AddDays(90).ToShortDateString();
