Remarks

Use the AlternateText property to specify the text to display for a HotSpot object in an ImageMap control when the image specified by the ImageUrl property is unavailable.

When an ImageMap control is rendered to a browser that does not support images, instead of displaying an image, it renders a hyperlink for each HotSpot in the ImageMap control. The control retrieves the text to display for each hyperlink from the AlternateText property for each HotSpot. When a user clicks one of the hyperlinks, it behaves like a HotSpot by either navigating to a specified URL, generating a postback to the server, or doing nothing.

When the ImageMap control renders to a browser that supports the ToolTips feature, the value of the AlternateText property is displayed as a ToolTip for the HotSpot.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and Globalization and Localization.
