The DataGridView control is highly configurable and extensible, and it provides many properties, methods, and events to customize its appearance and behavior. The DataGridView control makes it easy to define the basic appearance of cells and the display formatting of cell values.

Each cell within the DataGridView control can have its own style, such as text format, background color, foreground color, and font. 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.
