The DataGridColumnStyle.Abort(int) method is used by the System.Windows.Forms.DataGrid when the DataGridColumnStyle.Commit(CurrencyManager, int) method of the System.Windows.Forms.DataGridColumnStyle method returns false. In that case, the column value is rolled back to its previous value.
The System.Windows.Forms.DataGridColumnStyle must end any editing operations before returning. Use the DataGridColumnStyle.Abort(int) method to accomplish this.
The DataGrid.EndEdit(DataGridColumnStyle, int, bool) method of the System.Windows.Forms.DataGrid control indirectly invokes DataGridColumnStyle.Abort(int) if its ShouldAbort parameter is set to true.
