System.Web.UI.WebControls.Button.OnCommand Method

Raises the Button.Command event of the System.Web.UI.WebControls.Button control.

Syntax

protected virtual void OnCommand (CommandEventArgs e)

Parameters

e
The event data.

Remarks

The Button.Command event is raised when the System.Web.UI.WebControls.Button control is clicked. This event is commonly used when a command name, such as Sort, is associated with the System.Web.UI.WebControls.Button control. This allows you to create multiple System.Web.UI.WebControls.Button controls on a Web page and programmatically determine which System.Web.UI.WebControls.Button control is clicked.

Note:

The Button.Command event is raised through the control hierarchy in the form of the BubbleEvent.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The Button.OnCommand(CommandEventArgs) method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
