如何在SSRS中设置矩形的可见性

Question

I'm having some difficulty implementing the visibility of a rectangle and I used this line of code to set the visibility:

=IIF(Len(ReportItems!txtCountVolunteer.Value) > 0, true, false) 

Unfortunately it doesn't work.

Good day to you as well.

It seems like that you have got the logic reversed in the expression. There is "Hidden" property for a rectangle, and note that there is no "Visible" property. So the expression for the rectangle's "Hidden" property should be:

=IIF(Len(ReportItems!txtCountVolunteer.Value) <= 0, true, false)
