Change font size in SSRS dynamically

Question

In my report, am just trying to change the font size of the text box dynamically depending upon the length. My expression is,

=iif(Len(Parameters!CandidateName) < 27, "30pt","25pt")

here, if the length is > 27 it is displaying 25pt and if it is < 27 it is diplaying 30pt, and the size is not changing. Can anyone help me here. Thanks in advance.

Answer 1

Evaluate length of the Value of the CandidateName parameter:

=iif(Len(Parameters!CandidateName.Value) < 27, "30pt","25pt")
