                   {
                       
                       binding = new Binding("checked", dsMain.Tables[0], "service_request");
                       binding.FormattingEnabled = true;
                       
                       radioButton1.DataBindings.Clear();
                       radioButton1.DataBindings.Add(binding);
                   };                   if (dsMain.Tables[0].Rows[0]["service_request"].ToString() == "B")

                       radioButton2.DataBindings.Clear();
                       radioButton2.DataBindings.Add(binding);
                   };                   if (dsMain.Tables[0].Rows[0]["service_request"].ToString() == "C")
                   {
                       
                       binding = new Binding("checked", dsMain.Tables[0], "service_request");
                       binding.FormattingEnabled = true;
                       
                       radioButton3.DataBindings.Clear();
                       radioButton3.DataBindings.Add(binding);
                   };

Answer 1

 Name 命名一样就可以了。他们就是一组了。

Answer 2

可能考虑一下,binding的事件format和parseformat一个是从数据库出来时绑定的处理,一个保存到数据前的处理
