Answer 1

Create a class like:

class Sort : IComparer
{
    public int Compare(object x, object y)
    {
        return -int.Parse((string)x).CompareTo(int.Parse((string)y)); //sort descending
        //return int.Parse((string)x).CompareTo(int.Parse((string)y)); //sort ascending
    }
}

and do

grid.Sort( new Sort() );
