In the following article I will be showing on how to work with a Checkbox control in Universal Windows Apps.
CheckBox represents a control that a user can select (check) or clear (uncheck) form a list of options that a user can select, such as a list of settings to apply to an application. Both CheckBox and RadioButton controls allow the user to select from a list of options. CheckBox controls allow the user to select a combination of options. In contrast, RadioButton controls allow the user to select from mutually exclusive options.
In the following demo we are listing some skills from which user can select and the selected will be shown in a TextBlock shown below and unchecking the same will remove it also.
