ImageButton.Command Event
System.Web.UI.WebControls Namespace ImageButton Class
Occurs when an ImageButton control on a Web Forms page is clicked.
[ VB ] Public Event Command As CommandEventHandler [ C# ] public event CommandEventHandler Command; [ C++ ] public: __event CommandEventHandler* Command;
In [ JScript ], you can handle the events defined by a class, but you cannot define your own.
Event Data
The method assigned to handle the event is passed a CommandEventArgs object containing data related to the Command event. The following CommandEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| CommandArgument | Gets the argument for the command. This property is read-only. |
| CommandName | Gets the name of the command. This property is read-only. |
Remarks
A Command event is raised whenever an ImageButton control on a Web Forms page is clicked. This event is raised along with the imagebutton's Click event, and is commonly used when multiple ImageButton controls with different command names are defined on a Web Forms page.
The page framework passes the command name and argument of the imagebutton that caused the event to the designated event handler. This provides a convenient way to programmatically determine which command to perform.
For more information about handling events, see Web Forms Events Model.
