Examples

// Define the event handler that uses coordinate information through ImageClickEventArgs.
void ImageButton_Click(object sender, ImageClickEventArgs e) 
{
   Label1.Text = "You clicked the ImageButton control at the coordinates: (" + 
                 e.X.ToString() + ", " + e.Y.ToString() + ")";
}
' 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

Remarks

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.
