You can sort that particular column by 'DESC" so as per the dictionary text format it will sort the column and so the 'Open' will come first then 'Close' if it sorted in descending order.
You can use sorting either of the levels like described below :-
1) Sort it while fetching from database in query itself
ex :-
ORDER BY [StatusColoumn] DESC
2) Else you can apply default sorting for the grid on page load as below :-
ex :-
protected void Page_Load(object sender, EventArgs e)
{
if (String.IsNullOrEmpty(GridView1.SortExpression)) GridView1.Sort("SortExpression", SortDirection.Ascending);
}
