Answer 1

Sorry it took so long - I wanted to test before I answered, so I plopped this into Visual Studio to test first.

I had to do this in mine to get it to work:

foreach (DataGridViewColumn c in dataGridView1.Columns)
{
   c.SortMode = DataGridViewColumnSortMode.NotSortable;
   c.Selected = false;
}
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullColumnSelect;
dataGridView1.Columns[0].Selected = true;

Answer 2

Loop through the cells in the column and set their Selected property to true.
It sounds horrible, but I believe it's the only way to select an entire column and keep automatic sorting.

For example:

grid.ClearSelection();
for(int r = 0; r < grid.RowCount; r++)
    grid[columnIndex, r].Selected = true;
