  3. OnDisable - fired when the input is disabled
  4. OnEnable - fired when the input is enabled
  5. OnError - fired when the user enters invalid data
  6. OnFocus - fired when the input control gains focus
  7. OnKeyPress - fired when a keyboard key is pressed
  8. OnLoad - fired when the input control is loaded on the client
  9. OnMouseOut - fired when the mouse cursor leaves the input area
