RadListView supports appending additional data items to its current data source.
RadListView.appendData(array) method can be used to
add new items to an existing data source, or set the current data source if no previous
data is present. When new items are added to RadListView, existing items are not
cleared and rebound. Instead, RadListView only creates new items for the appended
data records, avoiding excessive databinding.
This demo shows an approach for binding JSON to RadListView. Additional data items
can be appended on demand on click of a button, or at predefined regular intervals.
