Report Viewer Control while report is being generated

Hello,
I am developing some reports and am using report viewer control to display the reports. I am getting the data for the report through a stored procedure which take around a min to return the data set.
I dynamically bind the data set returned from the stored procedure at runtime based on the selection of the report paramters. Once the report is displayed and the users wants to get a new report by changing their selection, the old report is still on the screen and unless the users notice the green bar at the bottom of the screen , there is no way to tell that their result is being processed.

I need some sort of notification for the user so that they realize that request has been submitted and the new report is being processed. I tried using Report.Refresh but that does not. Can anyone help please ?

Never mind, I figured it out...Here is what I did:

<script runat="server">
      private void Page_Load(object sender, System.EventArgs e)
      {
            btnSubmit.Attributes.Add("onclick", "document.getElementById('msgWait').style.display='block'");
      }
</script>

<form runat="server">
   <asp:Button id="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" /></p>
</form>

<div id="msgWait" style="display:none; color: red"><p>Please wait.  This may take up to a minute...</p></div>

Now as soon as the user clicks on the button , the message gets displayed to the user.
