Copying a DataGridViewRow to another DataGridView Control

Sometimes a simple task can be very tricky. Today I was trying to make a copy of DataGridView to another DataGridView, in the traget DataGridView I need to delete a few rows and possibly add a few new DataGridViewColumn(s), all these changes must have no impact whatsoever on the Original DataGridView object. Because of the nature of C#, object is passed by reference. So I cannot do things like DataGridView dgv_copy = dgv_original if I want to make some changes in the second DataGridView without affecting the original one.

What should I do? Firstly I need to create columns first, populate the DataGridViewColumns from the original to the new one. This is very straight forward, however when it comes to copy the rows. I came across a problem. The DataGridViewRow clone method does not work as expected. The Clone method copies the row and its property values, but does NOT copy the cell values that the row contains. So we have to write some code to copy the cell values. Please find the working example below and feel free to let me know should you have any queries.

private DataGridView CopyDataGridView(DataGridView dgv_org)
{
    DataGridView dgv_copy = new DataGridView();
    try
    {
        if (dgv_copy.Columns.Count == 0)
        {
            foreach (DataGridViewColumn dgvc in dgv_org.Columns)
            {
                dgv_copy.Columns.Add(dgvc.Clone() as DataGridViewColumn);
            }
        }

        DataGridViewRow row = new DataGridViewRow();

        for (int i = 0; i < dgv_org.Rows.Count; i++)
        {
            row = (DataGridViewRow)dgv_org.Rows[i].Clone();
            int intColIndex = 0;
            foreach (DataGridViewCell cell in dgv_org.Rows[i].Cells)
            {
                row.Cells[intColIndex].Value = cell.Value;
                intColIndex++;
            }
            dgv_copy.Rows.Add(row);
        }
        dgv_copy.AllowUserToAddRows = false;
        dgv_copy.Refresh();

    }
    catch (Exception ex)
    {
        cf.ShowExceptionErrorMsg("Copy DataGridViw", ex);
    }
    return dgv_copy;
}
