  Telerik MVC Grid - Sum error
  
  I am using the following line to get a column sum:
  columns.Bound(item => item.McGross).Width(50).Title("Amount").Aggregate(aggreages => aggreages.Sum()).Format("{0:c}").FooterTemplate(result =>
              { %><%= result.Sum.Format("{0:c}") %><% });
  
  I get error when any of the column valuse are null.  How can I use "if" null put "0" for that record.  Thanks in advance.
  
  A:
  
  The good people at Telerik has provided an answer, here it is:
  .FooterTemplate(result =>
  {
    %>Total Sum: <%=
      (result.Sum == null || (double)result.Sum.Value == 0.0)
        ? "Value not available"
        : result.Sum.Format("{0:c}")
      %><%
  });
  
  It worked. Hope this could help someone else.
