Remarks

The InheritedStyle property of the new DataGridViewRow objects has the same values as the InheritedStyle of the DataGridViewRow positioned at indexSource. The InsertCopies method adds shared rows to the DataGridViewRowCollection, if possible. Otherwise, the new rows are 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 System.Windows.Forms.DataGridView.Sort method in a DataGridView.RowsAdded event handler. You might also want to call the System.Windows.Forms.DataGridView.Sort method in a CellValueChanged event handler to sort the rows when the user modifies a cell.
