Properties

  Name Description
Public property Hierarchy Gets the IVsHierarchy representing the outer hierarchy of the item.
Public property IsNestedItem Gets whether this item is a nested item or not.
Public property IsRoot Gets whether the item is the root of its IVsHierarchy.

Public property NestedItemID Gets the item identifier representing the inner item in the NestedHierarchy.

Remarks

For items that belong to only a single IVsHierarchy, the IsNestedItem property will be false, and both the Hierarchy / ItemID and NestedHierarchy / NestedItemID pairs will be equal. For a nested item, the Hierarchy / ItemID pair represent the “outer” (nearest-to-the-root) pair, and the NestedHierarchy / NestedItemID pair represent the “nested” (child) pair.

A single item in the Solution Explorer (for example, a C# project node) can actually be composed of two different IVsHierarchy implementations with two different item identifiers. As a specific example, the “solution” is an IVsHierarchy representing the “tree” of items in the solution, but the solution’s IVsHierarchy does not know about the content of projects. A specific C# project in the solution is also a separate IVsHierarchy. The node representing the project itself might be node #50 in the IVsHierarchy for the solution, and node VSITEMID_ROOT in the IVsHierarchy for the project. IVsHierarchyItemIdentity and IVsHierarchyItem bind together these two different IVsHierarchy and item identifiers into a single concept.
