Adding Groups
Items in RadListView can be grouped conveniently into different groups, which will enhance your end-user experience when working with RadListView. Grouping the items at design time can be achieved by setting the EnableCustomGroups and ShowGroups properties of the control to true and, adding the desired groups into the Groups collection of RadListView. This collection is accessible either through the Smart Tag of the control or through the Groups collection property located in the property grid.
