Remarks

The DataGridViewCell class represents an individual cell in a DataGridView control. You can retrieve cells through the Cells collection of a DataGridViewRow.

The row and column for a DataGridViewCell identify the cell's location in the DataGridView. A typical cell contains data specific to the row and column in which it is contained. The cell can be customized in a number of ways by setting its properties and handling the events associated with it.

Notes to Implementers

When you derive from DataGridViewCell and add new properties to the derived class, be sure to override the Clone() method to copy the new properties during cloning operations. You should also call the base class's Clone() method so that the properties of the base class are copied to the new cell.
