Description
This article demonstrates how to implement check all functionality in the group items in RadListview.
Solution
It is necessary to add a RadCheckBoxElement to the ListViewElement that will manage all the check-boxes in the groups. We will create a custom ListViewDataItemGroup that stores the CheckState of data group item considering the toggle state of the inner items. It is also required to create a custom DetailListViewGroupVisualItem which represents the visual element that contains a RadCheckBoxElement. Once the visual element is toggled, it is necessary to update the CheckState of the respective data item.
