Binding A DataSource Table Column To A Form Object (RadioButtons)

Hi,

  I have a little question.  I have an application which interfaces with a SQL Express Database.   On a form, I want to bind a control which is made of several Radio buttons to a table column which is in fact a varchar(1).  This is the picture:

        Table column:  OptVisualRpt  varchar(1)

        Screen control:  2 radio buttons

                                    rb_VisRPTbImp_O    for "yes"

                                    rb_VisRPTbImp_N    for "no"

 

  I'm really scratching my head as how I can bind a single table column to my radio buttons controls.   I think that I just can't this way but rather have to use an intermediate variable or control. 

Solution 1?

 I thought of using a local variable that I would set to "y" or "n" following "CheckedChanged" events fired from radio buttons but I don't know how to bind this variable to my table column.                 

Solution 2?

  I thought of placing a hidden text control into my form, which one would be binded to my table column, that I would also set to "y" or "n" following "CheckedChanged" events fired from radio buttons.

Any of these solutions which would be feasible or any more neat way to do it?

Many thanks in advance,

Stéphane
