.NET Mobile Utilities

Utility controls support complicated user interfaces with minimum of code.

The AdRotator Control

This mobile page displays different advertisements:

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

<Mobile:Form runat="server">
<Mobile:AdRotator runat="server"
 AdvertisementFile="advertisements.xml">
</Mobile:AdRotator>
</Mobile:Form>

This is the ad file called "advertisements.xml":

<?xml version="1.0" ?>
<Advertisements>

<Ad>
<ImageUrl>image1.gif</ImageUrl>
<BmpImageUrl>image1.bmp</BmpImageUrl>
<WBmpImageUrl>image1.wbmp</WBmpImageUrl>
<NavigateUrl>http://www.1.com</NavigateUrl>
<AlternateText>Visit 1</AlternateText>
</Ad>

<Ad>
<ImageUrl>image2.gif</ImageUrl>
<BmpImageUrl>image2.bmp</BmpImageUrl>
<WBmpImageUrl>image2.wbmp</WBmpImageUrl>
<NavigateUrl>http://www.2.com</NavigateUrl>
<AlternateText>Visit 2</AlternateText>
</Ad>

<Ad>
<ImageUrl>image3.gif</ImageUrl>
<BmpImageUrl>image3.bmp</BmpImageUrl>
<WBmpImageUrl>image3.wbmp</WBmpImageUrl>
<NavigateUrl>http://www.3.com</NavigateUrl>
<AlternateText>Visit 3</AlternateText>
</Ad>

</Advertisements>

The Calendar Control

This mobile page displays a calendar:

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

<script runat="server">

Sub CalChanged(sender as Object,e as EventArgs)
lab1.Text="You selected " & c1.SelectedDate
ActiveForm=f2
End Sub

</script>

<Mobile:Form id="f1" runat="server">
<Mobile:Calendar id="c1"
 OnSelectionChanged="CalChanged" runat="server" />
</Mobile:Form>

<Mobile:Form id="f2" runat="server">
<Mobile:Label id="lab1" runat="server" />
</Mobile:Form>

In this example a calendar is displayed in the first form. When the user select a date from the calendar, the selected date is displayed in a new form.

The PhoneCall Control

This mobile page will display the text "Tove's number" and dial the number (555) 555-5555 when the user selects the text:

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

<Mobile:Form runat="server">

<Mobile:PhoneCall runat="server"
PhoneNumber="(555) 555-5555"
Text="Tove's number"
AlternateFormat="{0}" />

</Mobile:Form>

The attribute "AlternateFormat" has the value "{0}". This displays the text from the attribute "Text".

If you use the value "{1}" it will display the text from the attribute "PhoneNumber".

You can also use a construct like this: AlternateFormat="{0} is {1}". This will display the text "Tove's number is (555) 555-5555".
