Answer 2

Not sure if you are using any framework (EF, etc)

 

You will need to do this in code. Assume, you get either 1 or 2 or 3 or 4 from the database.

 

Then, in c# you write (something) like this...

 

radioButton1.checked = radioButton2.checked = radioButton3.checked = radioButton.checked = false; 

switch(radioButtonValueFromDb) 

{

   case 1:

       radioButton1.checked = true;

 

//all other 3 values... 

}
