Public Class CapabilityEvaluator

Public Shared Function ChkScreenSize(cap As System.Web.Mobile.MobileCapabilities, arg As [String]) As Boolean
Dim screenSize As Integer = cap.ScreenCharactersWidth * cap.ScreenCharactersHeight
Return screenSize < Integer.Parse(arg)
End Function

End Class

You add the following device filter element to the Web.config file.
<filter name="FltrScreenSize" type="MyWebApp.CapabilityEvaluator,MyWebApp" method="ChkScreenSize" />

You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
You create an AJAX-enabled Web form by using the following code fragment.
<asp:ScriptManager ID="scrMgr" runat="server" />
<asp:UpdatePanel runat="server" ID="updFirstPanel" UpdateMode="Conditional">

<asp:Button runat="server" ID="btnSubmit" Text="Submit" />
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel runat="server" ID="updSecondPanel" UpdateMode="Conditional">
<ContentTemplate> …
</ContentTemplate>
</asp:UpdatePanel>
