How to Formatting in DataGridView

The DataGridView control is highly configurable and extensible, and it provides many properties, methods, and events to customize its appearance and behavior. You can extend the DataGridView control in a number of ways to build custom behaviors into your applications.

The DataGridView control makes it easy to define the basic appearance of cells and the display formatting of cell values. Typically, however, multiple cells will share particular style characteristics. You can define appearance and formatting styles for individual cells, for cells in specific columns and rows, or for all cells in the control by setting the properties of the DataGridViewCellStyle objects accessed through various DataGridView control properties.

The following vb.net program shows how to implement different ways of cell formatting in a DataGridView control.
