The Image class provides a way to choose an image file based on device characteristics. For certain devices, you can specify built-in images by using a symbol : prefix as part of the URL in the ImageUrl property. For more information, see the Device-Specific section of the Image.
Note |
|---|
If your application relies on cookieless sessions, or might receive requests from browsers that require cookieless sessions, using a tilde ("~") in a path can inadvertently result in creating a new session and potentially losing session data. To set a property with a path such as ("~/path"), resolve the path using ResolveUrl("~/path") before assigning it to the property. |
The following code sample code shows how to use a <DeviceSpecific> control within an Image control to specify different images for different devices. If you have available a file named Sunshine.gif, it will appear in Internet Explorer. If you view the page on a WML device such as an OpenWave phone or a CHTML device, it will appear as a sun icon. The page also displays the name of the browser and the resolved name of the image.
