Remarks
The InheritedStyle property of the new row has the same values as the InheritedStyle of the row positioned at indexSource. The AddCopy method adds a shared row to the DataGridViewRowCollection, if possible. Otherwise, the new row is unshared. For more information, see Best Practices for Scaling the Windows Forms DataGridView Control.
Rows in the control are not automatically sorted when new rows are added. To sort new rows into their correct position, call the DataGridView.Sort method in a DataGridView.RowsAdded event handler. You might also want to call the DataGridView.Sort method in a CellValueChanged event handler to sort the rows when the user modifies a cell.
