Is there a way to tie checkbox column to data object, the grid is build on?

Hi,

Is there a way to tie checkbox column to data object, the grid is build on?
I'm talking about column option defined like this: {id: 'chk' ,isCheckColumn : true, editable:false}
My datasource is a local variable.
All my attempts are not successful.

Any ideas? Actually, I would prefer a sample code.

Thanks,
OKL

it's already tied to the first column in data array.
to get it call
grid.checkedRows property.
