Flex checkbox control example

The page provides illustration about the working of flex checkbox control. Example is based on registration for online training courses. On the registration form, trainee check marks the courses in which he/she is interested. After that it clicks on Post button to send its request. For check marking flex check boxes are created and for posting flex button control is used. Functionalities like getting marked courses data and processing it, is achieved via two void functions Course_selected and Request_Process, created in the example.

Flex check boxes controls possess a box and a label. On the box, check marks are marked and with label, information regarding the check box control is demonstrated.
