Trouble with UpdateProgress showing...


Recently I converted a project to VS.NET2010 and ASP.NET 4.0 (not convinced this is the problem, but regardless this is when the problem began) and now I am having an issue with an AJAX UpdateProgress showing. Here is the abrriviated code:

   <asp:UpdatePanel ID="UpdatePanelPostPageLoad" runat="server">
         <asp:Timer ID="tmrPostPageLoad" Enabled="false" Interval="100" OnTick="PostPageLoad_LoadData"
         <asp:Timer ID="tmrPostPageLoadPt2" Enabled="false" Interval="1" OnTick="PostPageLoad_LoadDataPt2"
         <%--Placing the UpdateProgress inside the UpdatePanel targeted--%>
         <asp:UpdateProgress ID="UpdateProgressPostPageLoad" runat="server" DisplayAfter="0" AssociatedUpdatePanelID="UpdatePanelPostPageLoad">

Detect Browser Screen Size??


Hi Everyone,  I need to detect the size of the user's screen for mobile devices (especially the BlackBerry). I've read a lot of pages that seem to refer me to the Request.Browser object, but I'm finding that this object doesn't have the correct values. For example, I have a BlackBerry and when I use the Request.Browser to get the screen size, it tells me it is 640x480. Well, I know it's not that big since an image of 300px wide just barely fits. Also, when I run on my desktop browser, it also says my screen is 640x480. I can assure you, it is not 640x480! ha!

  How does anyone reliably get the browser's screen size?? Do I have to revert to some kind of JavaScript? If so, where can I read more about it? Will it be any more reliable? Someone must have an idea about this. Thanks in advance!!

Obtain mobile device screen size



I am trying to get the screenHeight and width:


 // Get MobileCapabilities from current Request.Browser
        MobileCapabilities currentCapabilities = (MobileCapabilities)Request.Browser;
        // get a property of the  browser 
        Response.Write(currentCapabilities.ScreenPixelsHeight +  " <br>");
        Response.Write(currentCapabilities.ScreenPixelsWidth  + " <br>");


 but this is always show that the Height is 480 & the width is 640

I am trying on HTC with Opera Mobile 9.5

Any Advice?
