Remarks

The DataGridViewRowCollection contains the DataGridViewRow objects in a DataGridView control. You can retrieve an instance of this class through the control Rows property. The collection maintains a reference to the control through the DataGridView property.

To improve performance, a DataGridViewRowCollection includes shared and unshared rows. Shared rows share memory to reduce the cost of a large record set. If your record set is very large, you should be careful to keep the rows shared as much as possible.
