title: Regarding the radio button in salesforce
body: <p>I am searching for the solution regarding the radio button in salesforce apex programming. </p>
  
  <p>The scenario is I have one object in that one field is updated with value  when the radio button is selected in which there are three options like settings1 =0, settings2 =1, settings3 = 2. After that if I select setting1  then when I come to same page through command link of settings page. Previously selected <code>[settings1]</code> is not in a selected state radio button. I have written query to get that field value but it is not showing the selected radio button previously selected.</p>
