Answer 1

by creating a public method You can complete this task very easily like

public string testbind(object myvalue)
{
  if (myvalue == null)
  {
     return "NA value";
  }

  return myValue.ToString();
}

Label Code:

Or you may use

<%#(String.IsNullOrEmpty(Eval("TypeOfPainting").ToString()) ? "NA" : Eval("TypeOfPainting"))%>

You have to follow this type of scenarion.
