Datasets: Determine that a column value has changed and set a different column default value

Tags: Microsoft, Visual Studio 2005, .NET
I currently have a validation on the column titled "Status" in my ColumnChanging event.  I can validate the Status value (a boolean checkbox) but I cannot figure out how to check if the current column value has changed from the original value so that I can reset the "Status_Date" column to Today.  As I have it coded now, it resets the Status_Date anytime the entire row is in a modified state - not what I want.

If e.Column.ColumnName.Equals("Status") Then
           If CType(e.ProposedValue, String) Is System.Boolean.TrueString Or _
               CType(e.ProposedValue, String) Is System.Boolean.FalseString Then
                If e.Row.RowState = DataRowState.Modified Then
                    e.Row.Item("Status_Date") = Today
                    Me.dt_Status_Date.Value = Today
                End If
            End If
        End If
