  #206149

  Hi All,

  I'm using the below query to create a report,

  select 123 Value, Null String

  union

  select null, 'Days'

  And adding the fields to a table consisting of two columns.

  I'm using the following expressions in the first and second columns respectively.

  =Iif(IsNothing(Fields!Value.Value), "",Fields!Value.Value.ToString+" Min") --First Column expression.

  =Iif(IsNothing(Fields!String.Value), "",(Fields!String.Value).ToString) -- Second column expression'

  Is there anything wrong in the expressions or any suggestions?

  Please help me ASAP.

  Thanks in Advance.

  Regards,

  Ramu

  Hi Ramu

  I'm at home and don't have SSRS installed on this PC, so can't guarantee that my syntax will be right, but what I would aim to use is something like:

  First Column expression:

  =Iif(Fields!Value.Value is Nothing, "",CSTR(Fields!Value.Value)+" Min")

  Second column expression:

  All you are doing here is replacing NULL with "". Is there any reason to do so? Wouldn't a NULL and "" look identical on the report?

  I would just set the cell to =Fields!String.Value

  If you do need to remove any NULLs, I think this should work:

  =Iif(Fields!String.Value is Nothing, "",Fields!String.Value) --

  Hope this helps

  Alun

  Thanks a lot hkphooey for your reply,

  It worked exactly the way what i wanted.

  But can u explain what is the difference between the functions ToString to CSTR and IsNothing to Is Nothing.

  Thanks once again..:)
