Here are some code snippet that could help: You need to use the appropriate combination of checkbox, group and selector. 1) If you use a CheckGroup, then you have to build your checkboxes with Check instances, and they need to be children of the CheckGroup. In your example, add your dataview to the CheckGroup, so the Check instances are also underneath that. Then you can use CheckGroupSelector. 2) You can also use CheckBox instances - these don't need to be grouped together, they are just all separate boolean checkboxes. To select/unselect all of these you need to use CheckBoxSelector. 3) You can also use a CheckboxMultipleChoice together with CheckboxMultipleChoiceSelector. For your case I recommend option 1, since you are using listview. I hope this helps.
