Since Q2 2014 the RadListBox can be bound to RadClientDataSource control.
This functionality is provided out of the box through the server-side ClientDataSourceID property.
RadListBox needs the following properties in order to load its items properly:
- DataKeyField—defines the data source field name which will be considered as the key of the item.
- DataText—defines the data source field name which will be shown as text of the item.
- DataValue—defines the data source field name which will be considered as value of the item .
When the EnableLoadOnDemand property is enabled the RadListBox will request its items from the RadClientDataSource on portions.
