HierarchyData<(Of <(<'T>)>)> Members
The HierarchyData<(Of <(<'T>)>)> type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
|
HierarchyData<(Of <(<'T>)>)> |
Creates a new [HierarchyData{T}] wrapper around the specified model.
|
Methods
| Name | Description | |
|---|---|---|
|
|
GetChildren |
Returns the child nodes of this node as a HierarchicalModelList,
recursively wrapping each child in its own HierarchyData<(Of <(<'T>)>)> adapter
via [HierarchyConverter.ToHierarchicalModelList{T}].
Called by data-bound controls when expanding a tree node.
|
|
|
GetParent |
Returns the parent of this node, wrapped in a new [HierarchyData{T}] adapter.
Called by data-bound controls for upward navigation (e.g., breadcrumb rendering).
|
|
|
ToString |
Returns the string representation of the underlying data item
(via [IModelWithHierarchy{T}.Item]), which data-bound
controls may use as default display text.
|
Properties
| Name | Description | |
|---|---|---|
|
HasChildren |
Indicates whether this node has any child nodes, determined by checking
Children.Count > 0 on the underlying model. Data-bound controls
use this to decide whether to render an expand/collapse indicator.
|
|
|
Item |
Returns the underlying IModelWithHierarchy<(Of <(<'T>)>)> model.
Data-bound controls access this property to retrieve the data object for rendering.
Cast the returned object to T to access typed properties.
|
|
|
Path |
Returns the hierarchical path of this node. Currently returns
String as path-based navigation is not used
in the ACSP hierarchy binding model.
|
|
|
Type |
Returns the fully qualified type name of the wrapped model.
Used for type discrimination when multiple data types appear
in the same hierarchical data source.
