My datasource is XML (sharepoint list). I basically want to show the date formatted if the value in the field is a date and if not then show “NA”. For some reason, even when the data is a a string it is still trying to convert it to a date somewhere. Here is my code..

=IIF
(
ISDATE(replace(First(Fields!ows_Manufacturing_Date.Value, "DataSet1"),"datetime;#","")),
formatdatetime(replace(First(Fields!ows_Manufacturing_Date.Value, "DataSet1"),"datetime;#",""),2),
replace(First(Fields!ows_Manufacturing_Date.Value, "DataSet1"),"string;#","")
)

    The problem is that the IIF statement in SSRS doesn’t short circuit, it always evaluates both conditions, so even if the field is not a date, it still tries to do the formatdatetime function.

    (See this: SSRS iif function question)

    Instead of the IIF function, try using the SWITCH function instead:

    =SWITCH(First(Fields!ows_Manufacturing_Date.Value, "DataSet1")="string;#NA",
"NA",
First(Fields!ows_Manufacturing_Date.Value, "DataSet1")<>"string;#NA",
formatdatetime(replace(First(Fields!ows_Manufacturing_Date.Value, "DataSet1"),"datetime;#",""),2))
