Here is a straight forward way to do it. Whether this is performant
enough will depend upon the size of the DataView you are working with.

List<DataRowView> selectedItems = new List<DataRowView>(); //holds your
selected DataRowViews
private void button1_Click(object sender, EventArgs e)
{
   CurrencyManager cm =
this.dataGridView1.BindingContext[dataGridView1.DataSource,
dataGridView1.DataMember] as CurrencyManager;
    DataView dv = cm.List as DataView;
    int i = 0;
   foreach (DataRowView drv in dv)
   {
       if ((selectedItems.IndexOf(drv)) > -1)
       {
           this.dataGridView1.Rows[i].Selected = true;
       }
       i++;
   }
}

Hi Adam,

I agree to what Clay has suggested. There's no direct way but going round
in circles finding which DataGridView rows are to be selected.

I have also performed a test based on the sample code that Clay provides
and confirmed it works.

If you have anything unclear, please feel free to let me know.

Sincerely,
