Examples

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.

Note

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information, see ASP.NET Web Forms Page Code Model.

The following is the <deviceFilters> section of the Web.config file.

Remarks

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.

Constructors

Image() Image() Image() Image()

Creates a new instance of the Image class.
