I have an cell which contains a field member which is filled with 
String.Empty.  When I retrieve the value in the cell with 
Cells[0].Text.ToString() and try to compare it to String.Empty, I can't 
because it contains " ".  I really don't want to compare the value to 
that so how can I retrieve an empty cell so that it is String.Empty.

Yes - that's how empty GridView cells are rendered in HTML. A GridView is 
nothing more than an HTML table by the time ASP.NET has rendered it to the 
client browser - the rows are <tr> elements and the individual cells are 
<td> elements. Some browsers have problems displaying <td> elements which 
are completely empty, specifically with regard to borders etc, so ASP.NET 
inserts   to prevent this.

??? Why on earth not?

if (Cells[0].Text.ToString() == " ")
{
    // do something
}

What could be simpler...?

Ok that's fine.  I won't make it more difficult then it is. :)  But now I do 
have a real problem.  I am retrieving the 3rd row which happens to have no 
value in the cell and it is actually containing the value from the first row 
same cell.  When the gridview is displayed it is an empty cell but when I 
retrieve it by

GridView.Rows[index].Cells[0].Text.ToString().

It has the value of the cell from the first row.

What is happening here?

Difficult to tell without seeing your code but, if you do a View Source on 
the page in question, you will see the HTML table rendered from the GridView 
webcontrol - does that shed any light on it...?

I checked the source and rows  1 to 3 have an entry in the cell and rows 4 
to 5 have   in the cell.  When I step through the code and check the 
value at the cell from row 4, it has the value from the cell in row 1.

Please show the code you're using...
