Property Value

Type: System::String
The element name from which the image URL is retrieved for an advertisement.

You can create elements in the source XML file for a variety of purposes. For example, you may want to use the same XML file for both mobile pages and Web pages, but want a different image file for each one. Use the ImageKey property to specify which element in your XML file you want to use for the image URL.

You can also use separate <Choice> Element (.NET Framework Developer's Guide ) elements to override this setting to show alternate images for the advertisement.

The following code example demonstrates how to use the ImageKey property to select a specific item from a record in the XML file. This .aspx file specifies that the value for the image URL can be obtained from the <MobileImageSrc> element of the XML file, and uses a <Choice> Element (.NET Framework Developer's Guide ) element to select a different image URL if the user's browser requires WML markup.
