Tariere Ogidi, a member of our specialist Oracle APEX services team, uses the AJAX callback function to enforce the execution order of an interactive grid, which otherwise was leading to errors.
Recently I was posed with a situation where I needed to enable/disable some buttons depending on the selected row of an Interactive Grid (IG). The process is triggered on the selection of a row in the IG, which performs a calculation to determine whether the related buttons are enabled or disabled.
The following is an example of how the issue was resolved:
Below is a screenshot of the output of the application on the selection of an employee in department 30 and another in department 10. The UPDATE button is only enabled for the employee that satisfies the condition of belonging to department 30.
