Table control Access fields

Hi All,

I have 2 queries regarding table control.

<b>1.</b> Is it possible to access the table control changed text from screen? How?

Here I have to display the data in table control & when user selects change the changed text is to be saved in data base table when user selects save after making the changes.

<b>2.</b>How to enable only one selected row for updation.

Here if I say change all the rows are enabled for change mode.

Thanks & Regards,

Dilip
