Client-side Binding

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

RadNavigation 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 node.
  • DataFieldParentID—defines the data source field name which will be associated with the parent ID of the node.
  • DataText—defines the data source field name which will be shown as a text of the node.
  • DataNavigateUrlField—defines the data source field name which will be considered as a navigate URL of the node.

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

  • DefaultVB.aspx
  • DefaultVB.aspx.vb
  • scripts.js
