Freezing Header in a editable Grid

Hi All,

We do have a requirement in  a editable grid where we can make the Header to be freezed so that it will  still show while scrolling for a large no of datas.

Second thing is that Can we make the Selectable checkbox enable or disable for specific row based on some condition? Not all the rows.

Looking for the help.

Thanks
