System.Web.UI.WebControls Namespace Button Class
Occurs when a Button 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.
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.
A Command event is raised whenever a Button control on a Web Forms page is clicked. This event is raised along with the button's Click event, and is commonly used when multiple Button controls with different command names are defined on a Web Forms page.
The page framework passes the command name and argument of the button 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.
The following example demonstrates how to specify and code a handler for the Command event.
