How to make presence visible or invisible of a textfield

[Former Community Member]

I have a list of textfield, i use itextsharp (C#) to valorize them.
For example i valorize the textfield: "topmostSubform.Page1.codice_articolo_0" with:

if i valorize the textfield, i must make it visible, else if it has no value, i must make it invisible.

For every textfield i add this script:

But it doesn't work, i have all the textfield invisible!

How can i resolve?

this.rawValue == null might be evaluting "true" for everything. Can you disable the script for a few text fields and load the doc to see if the values are loading properly?

Are any of your fields invisible already? If not, can you remove the nested if statements?

if (this.isNull) this.presence = "invisible";

else this.presence = "visible"; //this line may not be necessary if they're starting visible

Logically, the original should work. On a small test form, I can't seem to make it fail. (To test, I created a small form with a field. added your code to the docReady event, and the field is visible if it has something assigned to it, invisible if it doesn't.)
