Detecting NULL dates and showing empty string in SSRS

Question

I\'m trying to format some cells in a Reporting Services report that will contain DateTime? values - or not.

If the underlying data has a NULL

Answer 1

I just tested the following expression and it replaced the null date with an empty string:

=IIF(Fields!DatumBSE.Value is nothing, nothing, FormatDateTime(Fields!DatumBSE.Value, 2))

The other suggestion that I would make is that you could format the date to the correct format in the report dataset by placing a CASE expression around the date value.
