在使用 contentpage/masterpage 时，我无法在单击按钮时在 asp.net 中运行进度条代码。
我已经检查了没有母版页的代码，它的工作很酷..但是在使用母版页时遇到了问题。我无法弄清楚的问题是什么？

 <%@ Page Title="" Language="C#" MasterPageFile="~/Admin.master" AutoEventWireup="true" CodeFile="UploadStudentDB.aspx.cs" Inherits="Admin_UploadStudentDB" %>

        <asp:Content ID="Content1" ContentPlaceHolderID="Contentplaceholder2" Runat="Server">
          <script language="javascript" type="text/javascript">
            var size = 2;
            var id = 0;

            function ProgressBar() {
                if (document.getElementById('<%=txtFilePath.ClientID %>').value != "") 
                {
                    document.getElementById("divProgress").style.display = "block";
                    document.getElementById("divUpload").style.display = "block";
                    id = setInterval("progress()", 20);
                    return true;
                }
                else {
                    alert("Select a file to upload");
                    return false;
                }
            }

            function progress() {
                size = size + 1;
                if (size > 299) {
                    clearTimeout(id);
                }
                document.getElementById("divProgress").style.width = size + "pt";
                document.getElementById("<%=lblPercentage.ClientID %>").
                        firstChild.data = parseInt(size / 3) + "%";
            }

        </script>
        <body>
            <div id="divUpload" style="display:none">
