- ## Method Details

  - ### addSelectionChangedHandler

    HandlerRegistration addSelectionChangedHandler(SelectionChangedHandler handler)
    Called when (row-based) selection changes within this grid. Note this method fires for each record for which selection is modified - so when a user clicks inside a grid this method will typically fire twice (once for the old record being deselected, and once for the new record being selected).

    NOTE: For updating other components based on selections or triggering selection-oriented events within an application, see the `selectionUpdated()` event which is likely more suitable. Calls to `getSelection()` from within this event may not return a valid set of selected records if the event has been triggered by a call to `selectAllRecords()` or `deselectAllRecords()` - in this case use the `selectionUpdated()` event instead.

    Parameters:
      `handler` - the selectionChanged handler
    Returns:
      `HandlerRegistration` used to remove this handler
