How to get updateable and not updateable rows in a single GridControl

Question

Hi,
i am using a gridControl based on an objectView "customer" with the attributes "cust_nr, cust_name, cust_updateable".
If customer data is updateable or not updateable set by the flag cust_updateable (true or false).
When the cust_updateable=false the user should not be able to update customer data in this row.
When the cust_updateable=true the user should be able to update customer data in this row.
Anyone who can help me?
Thanks !

Three possibilities come to mind:
If you want to manage this at the Application GUI level: If you want to prohibit them from ENTERING into a cell or EDITING a cell in the row, that's a different issue. ( I like blocking problems as early as possible ). I can see how one would do that with their own TableModel ( isCellEditable method, set FALSE if you do a getValueAt(thisRow,editableIdx)=="Y" or somesuch ). That might be a direction you might want to research and see if it is possible to do something like that with a gridControl. ( And post what you find! )
If you want to handle it at the DBA level: You might also look at "virtual private databases" in the Oracle dbms. Again, those rows would be trapped at commit time rather than "verb" time ( on the application screen ). The nice thing about that is that it protects the table against ALL comers, not just those that are going through a middle tier.
Your best bet if you want to follow the BC4J framework level: go into the Entity/ View Object impl and find the setMyAttribute method, and check the appropriate cust_updateable attribute ( in the same EO/VO ) and fire an exception. That'll trap it at data entry time, as well, and if you try and set it programmatically your try/catch block will fire up.
Good Luck
