If this is VB.NET then the AND operator is AndAlso

AndAlso and it's brother OrElse are better because:

  • Avoids executing part of a logical expression to avoid problems.
  • Code optimization by not executing any more of a compound expression than required

So your code should be 

If (Not (String.IsNullOrEmpty(e.Item.DataItem("DueDate")) AndAlso String.IsNullOrEmpty(e.Item.DataItem("ActualDate"))) ) Then 

    .... 
End If
