Gridview Previous value in RowDataBound

[=?Utf-8?B?cmxt?=]

I have a gridview, and in the RowDataBound event I do some processing on the
data. I need to know if the one of the columns has changed from its previous
value, but I do not see how to get the previous value. Doesn't viewstate have
that already?

I know I can access the current value with e.Row.Cells[0].Text, and I know I
can access a value in ViewState which I have added like ViewState["Status"].
What I want is something like this.
if(e.Row.Cells[0].OldValue.Text != e.Row.Cells[0].Text){
DoSomething();
}

OldValues collection is available in RowUpdated and RowUpdating events but
not in RowDataBound.
