Binding to Telerik ClientDataSource

Since Q2 2014 the RadMenu can be bound to RadClientDataSource control. This functionality is provided out of the box through the server-side ClientDataSourceID property.

RadMenu needs the following properties in order to load its items properly:

  • DataFieldID—defines the data source field name which will be associated with the unique identifier of the item.
  • DataFieldParentID—defines the data source field name which will be associated with the parent ID of the item.
  • DataText—defines the data source field name which will be shown as a text of the item.
  • DataValue—defines the data source field name which will be considered as a value of the item.
  • DataNavigateUrlField—defines the data source field name which will be considered as a navigate URL of the item.

Note: The client data source control is populated with demo data when fetch command is triggered.
