推荐答案

只是一个演示：

Just a demo:

public void PopulateStudent(ID) //your selected student
{
 if (Convert.ToInt32(dr[0]["StudID"]) != 0) // Meaning student is in database
 {
   RadioBtnList1.SelectedValue = dr[0]["StudentStatus"].ToString();
 }
 else
 {
  RadioBtnList1.Items[0].Selected = false;
  RadioBtnList1.Items[1].Selected = false;
 }
}
