<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

ASP.NET Web Forms won't let you put more than one form tag in a page - your master page contains that form tag, so this:
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<form id="form1" runat="server">
<div align="center">
will cause problems as it's trying to add a form tag. You don't need this form here anyways as the form tag in your master page is quite adequate.
<head runat="server">
<title></title>
</head>
<body style="direction:rtl;width:100%;background-color:#808080">
<form id="frmLevel2" runat="server">
<div dir="ltr" style="width:1000px;">
<asp:Button ID="btnExit" runat="server" OnClick="btnExit_Click" Text="خروج" />
</div>
<div>
<asp:GridView ID="GVLevel2" runat="server" Font-Names="Times New Roman" Font-Size="9pt" Width="700px" AllowPaging="True" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal">

<div>
<asp:Label ID="erorlabel" runat="server"></asp:Label>
<asp:Label ID="lblresult" runat="server"></asp:Label>
