HI,

    In my Visualforce page I have 3 radio buttons and 2 text fields. If I select the first radio button automatically field 1 is shown and field 2 is hidden.

I select radio button 1 & field 1 and save into the database. When I edit the previously saved data, radio button 1 is not selected. How can I make it selected in edit mode? In edit mode only field value is populating the radio button is not populating below image show it

    $('[id$="defaultcost"]').show();
    $('[id$="differcost"]').hide();
}
