ImageClickEventHandler Delegate

Represents the method that handles any events that are raised when a user clicks an image-based ASP.NET server control.

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

Public Delegate Sub ImageClickEventHandler ( _
	sender As Object, _
	e As ImageClickEventArgs _
Dim instance As New ImageClickEventHandler(AddressOf HandlerMethod)


Type: System.Object

The server control that is the source of the event.

Type: System.Web.UI.ImageClickEventArgs

An ImageClickEventArgs that contains event data.

This delegate defines the required signature for all click events raised when a user clicks an image-based ASP.NET server control. You must use the signature defined by this delegate for any OnServerClick event handlers that you create for an HtmlInputImage server control or any OnClick event handlers that you create for an ImageButton Web server control.

If you create a custom image-based ASP.NET server control that users can click, use this delegate to define the events associated with that user action.

For more information about delegates and how they interact with events, see Events and Delegates. For information about how to raise events, see Raising an Event.

' Define the event handler that uses coordinate information through ImageClickEventArgs. 
Sub ImageButton_Click(sender As Object, e As ImageClickEventArgs) 
   Label1.Text = "You clicked the ImageButton control at the coordinates: (" & _ 
                 e.X.ToString() & ", " & e.Y.ToString() & ")" 
End Sub
