<h3>Examples</h3>
<p><a target="_blank" href="showasp.asp@filename=demo_linkbutton">LinkButton</a><br />
In this example we declare one LinkButton
control and one Label control in an .aspx file. When the user clicks on the link, the lbClick subroutine is executed. The
subroutine sends the text "You clicked the LinkButton control" to the Label
control.</p>
