HtmlInputImage::OnServerClick Method (ImageClickEventArgs^)

 

Raises the ServerClick event.

Namespace:   System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

protected:
virtual void OnServerClick(
	ImageClickEventArgs^ e
)

Parameters

e
Type: System.Web.UI::ImageClickEventArgs^

An System.Web.UI::ImageClickEventArgs that contains event data.

The ServerClick event is raised when the user clicks an HtmlInputImage control.

The coordinates where the user clicks an HtmlInputImage control can be determined by using the ImageClickEventArgs::X and ImageClickEventArgs::Y properties of the System.Web.UI::ImageClickEventArgs object. The System.Web.UI::ImageClickEventArgs object is passed as a parameter to the user-defined event handler.

The origin (0, 0) is located at the upper-left corner of the image.

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

The OnServerClick 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.

Notes to Inheritors:

When overriding OnServerClick in a derived class, be sure to call the base class's OnServerClick method so that registered delegates receive the event.

The following code example demonstrates how to specify and code a handler for the ServerClick event to determine the coordinates where the user clicks the HtmlInputImage control.
