Hierarchical DataGridView Overview

How does Hierarchical DataGridView work?

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

1. Creating internal table (System.Data.DataTable) that contains a copy of data set with DataSource property.
2. Expanding internal table with additional columns in which data needed for hierarchy viewing is being generated and saved.
3. 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 user is not being altered in any way during this process.
4. Adjusting DataSource property to DataGridView control so that it points to a recreated and filled internal table.
5. Drawing control based on information stored in internal table and used for rendering the elements of hierarchy.
