HierarchicalModelDataSource<(Of <(<'T>)>)> Class
A generic IHierarchicalDataSource that binds a collection of
models implementing IModelWithHierarchy<(Of <(<'T>)>)> to hierarchical
data-bound controls.
Namespace:
AdvantageCSP.HierarchicalModelDataSourceUsage: Set the DataSource property with your hierarchy-aware collection, then assign this instance to a control's DataSource property and call DataBind().
Pipeline: When a control calls GetHierarchicalView(String), this class converts the DataSource collection into a HierarchicalModelList (via [HierarchyConverter.ToHierarchicalModelList{T}]), wrapping each model in a HierarchyData<(Of <(<'T>)>)> adapter. The view is cached after the first call so repeated binds don't rebuild the tree.
Assembly: AdvantageCMS.Core (in AdvantageCMS.Core.dll)
Syntax
public class HierarchicalModelDataSource<T> : IHierarchicalDataSource where T : IModelWithHierarchy<T>
