Remarks
Use the ImageField.DataAlternateTextField property to specify the name of the filed from the data source that contains the values to bind to the Image.AlternateText property of each image in an System.Web.UI.WebControls.ImageField object. The enables you to have different alternate text for each image displayed. The alternate text is displayed when an image cannot be loaded or is unavailable. Browsers that support the ToolTips feature also display this text as a ToolTip.
You can specify alternate text that applies to all images by setting the ImageField.AlternateText property instead of this property. If both the ImageField.AlternateText and ImageField.DataAlternateTextField properties are set, the ImageField.DataAlternateTextField field takes precedence.
