无法在aspx页面

Question

我正在尝试填充ContentPlaceHolder中的表的数据，但它没有填充。早些时候我在另一个带有body标签的aspx页面中尝试了相同的代码，并在那里填充。这里我不能在ContentPlaceHolder中放置body标签。我将请求发送到web api以获取数据，我获取JSON格式的数据。我不确定，但我觉得ContentPlaceHolder有些不好。

<%@ Page Title="" Language="C#" MasterPageFile="~/RLCS_Connect/TLConnect_New.Master" AutoEventWireup="true" CodeBehind="ShowNoOfLocations.aspx.cs" Inherits="TLConnect_Staffing.RLCS_Connect.ShowNoOfLocations" %>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

    <div>  
        <h2><b>Location Table:</b></h2>  
        <table id="Location" cellpadding="3" cellspacing="3" border="2" width="600px">  
            <tr>
