How to DataGridView Template

There are situations that you want greater control over the appearance of DataGridView rows than what is provided by the various DataGridView cell style properties. The row template gives you greater control over the appearance and behavior of rows than the RowsDefaultCellStyle property provides. With the row template, you can set any DataGridViewRow properties, including DefaultCellStyle. When displaying external data, however, the rows are generated automatically, but they are based on the row template, which you can set to an instance of your custom row type.

The following vb.net code example illustrates how to use the row template to specify an initial row height and a minimum row height and BackColor.
