How to programmatically set focus on a row in a WinForms DataGrid when selecting it?

Question

I have a WinForms DataGrid (not DataGridView). When I manually select a row, the row indicator, shown in the first image below, shows on the selected rows. However, if I set the DataGrid's datasource after a save and programmatically select the second row using: datagrid.Select(1), the second row gets the highlighted background color but the focus indicator is on the first row as shown in the second image below.

Is there a way to make the selected row get focus and have the indicator display for the row?

Since this is the old System.Windows.Forms.DataGrid, the Row selection method is slightly different than the DataGridView's.

You can select a Row, as you're doing, with the Select() method.
This doesn't change the Current Row. To make a Row the Current, you can use the CurrentRowIndex property.
Combined, these two move the selection and set the Current Row.

 // Selects and highlights the Row at index 1
 dataGrid.Select(1);
 // Make the Row at index 1 the Current
 dataGrid.CurrentRowIndex = 1;

Something similar in a DataGridView:
_{(One of the methods that can be used to achieve this result)}

// Move the focus and selects the Row at index 1
dataGridView.Rows[1].Selected = true;
// Make the Row at index 1 the Current setting the CurrentCell property
dataGridView.CurrentCell = dgvTest.Rows[1].Cells[0];
