SSRS隐藏表达式字段值为空白的行

Question

I have a field in my SSRS report that derives a value based on an expression. The expressions is a simple Lookup between 2 datasets and is working fine. It does return some NULL values and what I would like to do is not display the rows where the expression produces a NULL value. I know how to do this on a field that is not based on an expression but not on a field that is. Anyone know how this can be done? Thanks

Answer 1

Chances are, it will be something like the expression below on the Hidden property of whatever it is you are trying to hide/show.

=IIf(IsNothing(<your Lookup expression>), True, False)

Add any other checking in there too, if need be.

UPDATE:

To make this work on the entire row. Right-click on a row header in design mode, and choose Row Visibility... Click Show or hide based on an expression . Add the expression you now have in there.
