The DataGridViewTriState enumeration is useful whenever a third state is needed in addition to the two states of the Boolean type. For example, the DataGridViewCellStyle.WrapMode property is of type DataGridViewTriState so that a DataGridViewCellStyle object can indicate no preference in regards to the text wrapping of a cell value, and can instead indicate that the WrapMode value of a different DataGridViewCellStyle object should be used.
