<head runat="server">
    <title>Create Aspx Page Dynamically in Asp.net</title>
</head>
<body>
    <form id="form1" runat="server">
        <table align="center">
            <tr>
                <td><b style="font-size:large">Enter WebPage Name:</b></td>
                <td>
                    <asp:TextBox ID="txt_Pagename" runat="server"  Height="30px"  /></td>
            </tr>
            <tr>
                <td>&nbsp;</td>
                <td>
                    &nbsp;</td>
            </tr>
            <tr>
                <td colspan="2">
                    <asp:Button ID="btn_CreatePage" runat="server"
                        Text="Create ASPX Page" 
                        OnClick="btn_CreatePage_Click"
                        Height="40px" 
                        BorderStyle="None" 
                        BackColor="Green" 
                        ForeColor="White" />
                    &nbsp;
                    <asp:Button ID="btn_RedirectPage" runat="server" 
                        Text="Redirect to Created Dynamic Page" 
                        OnClick="btn_RedirectPage_Click"
                        Height="40px" 
                        BorderStyle="None" 
                        BackColor="Blue" 
                        ForeColor="White" /></td>
            </tr>
        </table>
        <br />
        <center><asp:Label ID="lbl_msg" Font-Size="x-Large" runat="server" /></center>
