jQuery Grid Plugin - jqGrid

Hi folks;

  I have an application where I want to update a grid periodically in response to a timer, and obviously I want that update to be suppressed when a row is being edited.  I know that I can see the initial selection of a row for editing via onSelectRow(rowid,status).  However, the row can get un-selected if the user hits the escape key, causing restoreRow to fire.  I cannot seem to get anything like onRestoreRow(...) to work, and the 'selrow' variable does not change when the selection is escaped in this way.

  Is there a way to detect if any row is selected for row editing?  Failing that, is there a way to attach a callback to the restoreRow event?

Thanks!
