Show a webpart on every page automatically

Question

Is it possible to add a web part on every page of a subsite automatically? Can the web part use the same config as the other pages it is one?

Answer 1

With custom code you could iterate over all the (sub)sites and pages and add it programmatic. Some handy work is needed. In this option you can set all the properties you want when adding the webpart to a page. Each page has is own unique config settings.

An other option is to add the webpart to the masterpage. Each page using the edited masterpage would show the webpart. Adding a webpart to a masterpage can be tricky (I haven't done it myself, and I don't know how the settings are stored/set in this scenario).
