Gets or sets the alternate text displayed for an image in the System.Web.UI.WebControls.ImageField object.
Syntax
[System.ComponentModel.DefaultValue("")]
public virtual string AlternateText { set; get; }
Value
Documentation for this section has not yet been entered.
Remarks
Use the ImageField.AlternateText property to specify the alternate text for the images displayed in an System.Web.UI.WebControls.ImageField object. 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.
When this property is set, all images displayed in an System.Web.UI.WebControls.ImageField object share the same alternate text. As an alternative, you can bind the alternate text to a field in a data source by setting the ImageField.DataAlternateTextField property instead of this property. This allows you to have different alternate text for each image displayed. If both the ImageField.AlternateText and ImageField.DataAlternateTextField properties are set, the ImageField.DataAlternateTextField property takes precedence.
The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see System.ComponentModel.LocalizableAttribute and ASP.NET Globalization and Localization.
