Please Wait Screen for heavy loading task

To display Please Wait Screen

Add Following line in .aspx file

In head Tag

<head runat="server">
    <title>Please Wait Screen</title>
    <script language = "javascript">
    function showPleaseWait()
    {
        document.getElementById('PleaseWait').style.display = 'block';
    }
    </script>
</head>

In Body Tag

<body>
    <form id="form1" runat="server">
        <div class="helptext" id="PleaseWait" style="display: none; text-align:right; color:White; vertical-align:top;">
            <table id="MyTable" bgcolor="red">
                <tr>
                    <td>
                        <b><font color="white">Please Wait...</font></b>
                    </td>
                </tr>
            </table>
        <div>
            <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click"  onmouseup="showPleaseWait()"/>    
Note: here "Please Wait Screen" display logic is on mouse up event, so whenever heavy task started on button click event, "Please Wait..." Message will be displayed.
I have read this interesting code on gridviewguy.com.

Very, very sharp. Much lighter weight and less complex than some other solutions I've seen. Best of all, it works (in .NET 3.5 anyways)!! Nice job!

I was looking at couple of other approaches as well.I was impressed with this piece of code its light and crisp. I made a small modifications i used the OnClientClick instead of onmouseup

Nice Job Vallab

Very good. I was looking for this kind of code. Thanks a lot. But this div is very small, i need like which need to lock my page entire until the operation get over. And also i m using master pages(asp.net 2.0). How to achieve it..
