Want to throw an error message if a real control value exceeds a particular value on a form. As this control is the sum of the row of a grid.
if the value in the real control is equal to particular sum (lets say 100000) then the user can not create a new record.
You can read the value from this real control in code. And if your form updates this field when something happens, you need to read that value again.
Then you just need to call yourDataSource.allowCreate(false) once the value exceeds certain limit.
There is an issue, After I delete one record. This control is not getting updated with the calculation of the record.
Where do you have the trigger for the calculation? Seems this trigger is in a place that doesn't get hit when a record is deleted.
You need to either move this trigger to a place where it's hit also when a record is deleted, or add a new trigger in data source delete method.
Thank You Nikolaos.
