Property Value
The command name associated with the ImageButton control. The default value is String.Empty.Use this property to specify the command to perform when the ImageButton control is clicked, such as Sort, Cancel, or Edit. This allows multiple ImageButton controls to be placed on the same Web page. The value in this property can then be programmatically identified in the OnCommand event handler to determine the appropriate action to perform when each ImageButton control is clicked.
Supplemental information about the command, such as specifying ascending sort order, can be included by using the CommandArgument property.
This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and Introduction to ASP.NET Themes.
The following example demonstrates how to use the CommandName property to associate a command name with an ImageButton control.
