Summary

Hierarchical DataGridView by Application Aspect (Raverus)

URLs: hierarchicaldatagridview, application-aspect, application aspect, applicationaspect

Organize, edit and display data in hierarchical form. Hierarchical DataGridView is a .NET WinForm grid control that organizes, edits and displays data in hierarchical form. Hierarchical DataGridView is compatible with Visual Studio 2005 and Visual Studio 2008. It is aimed at developers looking for a .NET grid control with data relation, self-referencing hierarchy, datastructure, multilevel data, master-detail, parent-child, category-subcategory, tree or recursion functionality.

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 a simple Excel sheet.

The 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 is also supported.

After setting the DataSource property and some additional properties (PrimaryKeyColumnName, HierarchicalColumnName and RootValue), the Hierarchical DataGridView control automatically displays data in hierarchical form in the following way:

Creating an internal table (System.Data.DataTable) that contains a copy of the data set with the DataSource property

Expanding the internal table with additional columns in which data is needed for hierarchy viewing is generated and saved

Processing data set with DataSource property, using information set with PrimaryKeyColumnName, HierarchicalColumnName and RootValue, and filling additional columns of internal table with specific values. Data that is set by a user is not altered in any way during this process

Adjusting DataSource property to DataGridView control so that it points to a recreated and filled internal table

Drawing control based on information stored in internal table and used for rendering the elements of hierarchy

You can use Hierarchical DataGridView component in many various situation such as: project management, organizational structures, task management, file and directory browsing, etc.

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). At the same time a developer does not have to make any effort to prepare and transform the data that they have got from a 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).
