Thanks, but I still get the index out of range exception when calling the above code.
i can't use "GridView.ClearSelection(1, 1, true)" either as i am told that that method is inaccessible due to its protection level.

GridView.Sort(GridView.Columns[1], ListSortDirection.Descending);
GridView.Rows[0].Selected = true;

	dataGridView1.DataSource = dt;

The entire event handler is kinda big with different sub methods

I are Troll

GridView.Select();
GridView.ClearSelection();
GridView.Rows[0].Selected = true;

GridView.Sort(GridView.Columns[1], ListSortDirection.Descending);

but it still only shows the first row selected but then continues from the original row when using the arrow keys. did your code still work after trying a sort operation like:

private void Form1_Load(object sender, System.EventArgs e) 
{
	DataTable dt = new DataTable("employee");
	dt.Columns.Add("firstname");
	dt.Columns.Add("lastname");
	dt.Rows.Add("john", "doe");
	dt.Rows.Add("johnny", "walker");		

	dataGridView1.DataSource = dt;
	dataGridView1.Sort(dataGridView1.Columns[1], ListSortDirection.Descending);
}
void HandleClick(object sender, EventArgs e)
{
	dataGridView1.ClearSelection();
	if (dataGridView1.Rows.Count > 0)
        {
                // Highlight the row;
		dataGridView1.Rows[0].Selected = true;

                // Move the input-focus rectangle;
	        dataGridView1.CurrentCell = dataGridView1.Rows[0].Cells[0];
        }
}
