I have a Master /Detail grid combo (JQGrid 3.5.3). The detail grid has navigator buttons for adding and editing records. I want to prevent the user from trying to add detail records if no row is selected in the master grid. I would like to either trap the details grid's beforeShowFormEvent and cancel the add form from displaying…. OR just not have an add button displayed and then dynamically add the detail grid add button when a master row is selected. Unfortunately I don't know how to do either of these options. Any direction on either of these options is much appreciated.

Thanks,

Mike
