delete record button disabled

Hello,

I have created a form with a grid and delete record command button in actionpane. I have granted full control privileges to the users who wants to access this form, however when a systerm administrator user accesses the form, he can see the delete record command button enabled, when non system administrator user logins with full control, delete record button is disabled. I checked privileges and permissions, they are granted at form and table levels, yet still the user cannot see delete record button enabled.

Any good feedback will be highly appreciated.

Thanks,

Salman
