How do I make the DataGridView show the selected row?

Question

I need to force the DataGridView to show the selected row.

In short, I have a textbox that changes the DGV select

Answer 1

int rowIndex = -1;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
    if (row.Cells[0].Value.ToString().Equals(searchString))
    {
        rowIndex = row.Index;
        break;
    }
}
if (rowIndex >= 0)
{
    dataGridView1.CurrentCell = dataGridView1[visibleColumnIndex, rowIndex];
}

visibleColumnIndex - selected cell must be visible
