MS CRM - setVisible

Question

I am newbie with CRM and I was googling for how to hide and show a text field using jScript library in MS CRM (online) and found several options of using the function setVisible.

I tried those options:

1. Xrm.Page.ui.tabs.get('new_fieldname').setVisible(false);
2. Xrm.Page.data.entity.attributes.get('new_fieldname').setVisible(false);
3. Xrm.Page.getAttribute('new_fieldname').controls.get(0).setVisible(false);

But only the last one is really working. The first option gives me an error message.

What is the different between them?

Answer 1

Just to add to the points already made..

The difference between

Xrm.Page.ui.tabs.get('new_fieldname').setVisible(false);

And

Xrm.Page.getAttribute('new_fieldname').controls.get(0).setVisible(false);

The first refers to a tab (Xrm.Page.ui.tabs), the second refers to an attribute (Xrm.Page.getAttribute).

So if you wanted to hide a whole tab, its sections and fields you can use the first one. If you want to just hide an individual field you can use

Xrm.Page.getControl("new_fieldname").setVisible(false);

Which is itself a shortcut from

Xrm.Page.ui.controls.get('new_fieldname').setVisible(false);
