I need an expression to get me the LAST DAY of the month for a given date.
What I already have an is nearly working is the following expression:
=CDATE(CSTR(DATEPART(DATEINTERVAL.YEAR, Fields!Date_Floor.Value)) & "/" & CSTR(DATEPART(DATEINTERVAL.MONTH, Fields!Date_Floor.Value)) & "/" & CSTR(DATEDIFF(DATEINTERVAL.DAY, Fields!Date_Floor.Value, DATEADD(DATEINTERVAL.MONTH, 1, Fields!Date_Floor.Value))))
The above expression works nearly fine except if the input date is already the last day of a month then it seem to subtract one day... For example:
If Input date is: 2011-05-31 then the expression returns: 2011-05-31 which is wrong. It must return 2011-05-31 as the last the of May (05).
Please help me fix this expression.
