在 RDLC 表达式中，如何放置多个条件？

Question

In RDLC report, I have a tablix on which I have already applied one condition to make it HIDDEN/VISIBLE.

=IIF(First(Fields!IsSatisfactory.Value, "DataSetCNGCertificates"), true, false)

But now I need to apply this also,

=IIF(Fields!CNGStationStatus.Value = "2", true, IIF(Fields!CNGStationStatus.Value = "3", true, false))

but not sure how to put both together. The later one shall be the first ot be checked.

Answer 1

Why not just return the answer... Ex: (x=1 or x=2 or y='test')... The answer will return true or false, so you don't need 3 nested IIF() constructs

Answer 2

If I understand you correctly you want the condition to check first the CNGStationStatus if its 2 , else, if its 3 , else, if IsSatisfactory is true.. Why not keeping with the nesting like:

=IIF(Fields!CNGStationStatus.Value = "2", true, IIF(Fields!CNGStationStatus.Value = "3", true, IIF(First(Fields!IsSatisfactory.Value, "DataSetCNGCertificates"), true, false)))

?

Using the AND operator should be used if you like to check the condition at once:

=IIF(Fields!CNGStationStatus.Value = "2" AND Fields!CNGStationStatus.Value = "3", true, IIF(First(Fields!IsSatisfactory.Value, "DataSetCNGCertificates"), true, false))
