OnClientCheckStarted

The OnClientCheckStarted client-side event occurs when the spell check begins and before the spell check dialog appears.

The event handler receives parameters:

1. The spell checker instance that fired the event.

2. Event arguments with the following properties:

   1. set_cancel: Can be used to cancel the event. Calling set_cancel(true) prevents the spell check from continuing.

The example below displays the discontinues the spell check if the contents of "TextBox1" contain the string www.telerik.com.

ASP.NET

function checkStarted (sender, args)
{
   if ($get("<%= TextBox1.ClientID %>").value == 'www.telerik.com')
   {
	   args.set_cancel(true);
   }
}
...
<telerik:RadSpell
   ID="RadSpell1"
   runat="server"
   ButtonType="PushButton"
   ControlToCheck="TextBox1"
   OnClientCheckStarted="checkStarted"
/>
