The trick that we used in our project is creating the UpdateProgress as a div which overlap all page controls and cover the whole page.

The div I am talking about will have fixed position start at 0;0; width and height is big enough to cover the entire page. the z-index (important key) is higher than any another (let say 100) so it will overlap the rest of the controls -> no controls is accessible during the progress. The div will also have transparency for better layout using filter (standard CSS).

The Css class .modalProgress  has already cover crossing browser problem. the width and the height I put fixed value to make sure it works for you. You can change it to percentage if you want.

Plug it in your code and see how it's look like

.modalProgress
{ 
	clear:both; 
	float:left; 	
	margin:0px;
	z-index:100;
	position:absolute;
	left:0px;
	top:0px;
	width:1200px;
	height:1000px;			
	background-color:Gray; 
	filter:alpha(opacity=50);
	opacity:0.5;
	-moz-opacity:0.5;
	-khtml-opacity: 0.5;
}
 
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="updtPanelModalPopup" DynamicLayout="true">
   <ProgressTemplate>
        <div class="modalProgress">
	   Loading... please wait.... <br />
	   <img alt="" src="/Images/ajax-loading.gif" />
        </div>
   </ProgressTemplate>
</asp:UpdateProgress>

Would it also be possible for users to use the Tab button to give focus to the overlapped controls, thus meaning it would technically be possible for users to click buttons and such during processing?
