Hierarchical DataGridView can be seen as a mixture of Visual Studio 2005 or Visual Studio 2008 DataGridView, Microsoft Project or Microsoft Access data table and simple Excel sheet.

A special feature of Hierarchical DataGridView is its ability to analyze, process and display hierarchical data created in a flat structure (typically in System.Data.DataTable or any other System.Windows.Forms.BindingSource object). At the same time developer does not have to make an effort to prepare and transform the data that he, for example, has got from relational database, into a form suitable for hierarchical viewing (e.g., he does not have to build and fill any collection of nodes, that reflects data hierarchy, to enable the viewing of data in this control).

If you are a Visual Studio 2005 or Visual Studio 2008 developer and the terms such as data relation, self referencing hierarchy, data structure, multilevel data, master-detail, parent-child, category-subcategory, tree or recursion describe the problem that you have, Hierarchical DataGridView is the right component to solve it.

Hierarchical DataGridView control supports data binding to any data source that implements IList, IListSource, IBindingList and IBindingListView interfaces such as BindingSource, Collections, Lists, Business Objects, etc. Binding to Nullable Data Types are also supported.
