Setting a particular page type defaults for basic properties?

When you add a field for the page type, in the Field type field, select Page field. Then you can select the appropriate fields for the navigation settings in the Field name field and set their default value.

If that somehow doesn't work out, you can try setting the values of those fields via handling the page insert event.

Hello Dat -

I had tried that with the fields DocumentShowInSiteMap and DocumentMenuItemHideInNavigation for the Page Fields, and while the Form tab shows these fields they don't reflect the defaults I had set, and when I go into the Navigation settings those defaults are not applied. They still need to be set manually for each new page of that type. Is there some other setting to make these apply to newly created pages?

According to this question, setting default values for those fields via the form field editor seems to be buggy and Kentico might not have ever fixed it. The workaround is to handle the document insert event.
