How to check a CHECKBOX in grid which is not related with datasource on selecting a record?

hi friends,

I am facing a very serious problem, where i have a form with a grid of 4 fields of table and one checkbox control created in design. Here, whenever i select a record in the grid the checkbox has to be checked. (i dont know this check box to be a table field).

I know the same functionality is done in Planned production order screen, etc…

But that has too many methods which is go on calling inside and inside.

Please help to solve this.

your help is most Appreciable.

Thanks a lot,
