.NET Mobile Example

The Mobile ASP.NET Page

Mobile Controls are the main building blocks of mobile applications.

Mobile Controls are similar to Web Controls in ASP.NET.

If you are not familiar with ASP.NET development, you should leave this tutorial and study our ASP.NET tutorial first.

This ASP.NET page displays “Hello W3Schools” as an WML card in an WML enabled cell phone:

<%@ Page
Inherits="System.Web.UI.MobileControls.MobilePage" %>
<%@ Register
TagPrefix="Mobile"
Namespace="System.Web.UI.MobileControls"
Assembly="System.Web.Mobile" %>

<Mobile:Form runat="server">
   <Mobile:Label runat="server">Hello W3Schools
   </Mobile:Label>
</Mobile:Form>

The Page directive tells ASP to use (inherit) mobile page handling instead of regular page handling (like the one used for traditional browsers)

The Register directive defines the prefix that will be used for mobile controls. We have used "Mobile", but you can use any prefix you like.

The <Mobile:Form> element tells the server to create a mobile form control.

The <Mobile:Label> element tells the server to create a mobile label control with the text “Hello W3Schools”.

The Mobile ASP.NET Output

When the ASP page executes, it will produce this output to a WAP enabled mobile phone:

<?xml version='1.0'?>
<!DOCTYPE wml PUBLIC 
'-//WAPFORUM//DTD WML 1.1//EN'
'http://www.wapforum.org/DTD/wml_1.1.xml'>

<wml>

<card>
<p>Hello W3Schools</p>
</card>

</wml>

While this output will be produced for a Pocket PC:

<html>
<body>

<form id="ctrl1" name="ctrl1" method="post"
action="example.aspx">
<div>Hello W3Schools</div>
</form>

</body>
</html>

Conclusion

.NET Mobile will generate WML code for cell WAP enabled cell phones and HTML code for devices like the Pocket PC.

By detecting the browser, .NET Mobile will output correct content, providing developers with a powerful tool to develop single applications that will serve many different mobile devices.
