Client-side Configuration

Changing spell properties on the client side.

This example demonstrates how you could launch RadSpell with client-side code.  You can now change some of the parameters by using the RadSpell object without posting back to the server.

The required steps are as follows:

  • Obtain a RadSpell reference by using the static getRadSpell method, passing it the RadSpell ClientID
  • Set the properties
  • Start the spellchecking by calling the startSpellCheck method.

Note: When checking a client-side element you need to set the IsClientID property to true.
