Checkedlistboxcontrol to implement check boxes for radio and multi-select functions

Due to work needs, need to implement check box of radio and multi-select function, find a lot of information is not very full, after two days of digging and digging, finally finished O (∩_∩) o haha ~

With the Checkedlistboxcontrol control in the dev control, of course, the check box combo control in VS should be implemented as follows, and you can try it (⊙o⊙).

Code come O (∩_∩) o haha ~

1   //first trigger the SelectedIndexChanged event before triggering the ItemCheck event2        3         //stores the value of the selected check box4         stringstrgxy=string.
