TabStrip / Declarative DataSources

Configurator
Select a declarative datasource:

  • RadTabStrip supports binding to various types of data sources, including declarative datasources.

    Some of the declarative data sources are inherently hierarchical. These include SiteMapDataSource and XmlDataSource. When data-bound to these types of data sources, RadTabStrip automatically creates the tab hierarchy. There is no need to use the DataFieldID and DataFieldParentID properties.

    The AccessDataSource is a table-based DataSource component. It can be used to bind the tabstrip declaratively at design time. As with binding to a DataSet, DataTable, or DataView, you can use the ID-ParentID relation to establish a hierarchy among the tabs.

    RadTabStrip supports binding to an ObjectDataSource as well. In addition to the standard Tab properties (Text, Value, Navigate Url, etc.) that can be bound to the underlying business objects, the DataFieldID and DataFieldParentID properties can be specified, too. In this way, RadTabStrip can create a hierarchy of Tabs.

    Still, the business objects should provide the data needed for the RadTabStrip to build the hierarchy. If the ParentID property of the business objects are of nullable or reference type, then null values denote root Tabs. In case, the ParentID property is of value type (Integer, Guid, etc.), '0'/'Guid.Empty' values denote the root Tabs.

    For more details on the aforementioned algorithm, please read the documentation topic - Binding to object-based data sources.
