In the code samples above we show how you could attach r.a.d.spell to almost all of the HTML editable elements: textarea, div, etc. Again you have to use the ControlToCheck property, but since this time the spellchecker is launched client-side you also have to set the IsClientID property to "true".

e.g.
<radS:RadSpell id=spell1 ButtonCssClass="button" IsClientID="true" ControlToCheck="textarea1" Runat="server"></radS:RadSpell>
