Mobile Value Picker, with properties to allow the picker to work client-side and server-side. Picker datasources available are:

• dominoView
• NotesDocument
• SimpleValuePicker

Client-Side Mobile Pages are the recommended option, to minimise requests back to the server via mobile networks which tend to have greater latency and worse reliability that desktop networks.

For a video on setting up a mobile XPage to work with the Mobile Value Picker client-side, see the video I made for NotesIn9.

For blog documentation on setting up a mobile XPage to work client-side or server-side with the Mobile Value Picker, see the series on my blog.

Both were made before the mobile picker page was extended into this reusable custom control. But the only changes have been to extend the custom control to use not only a Notes View but also a Notes Document or the SimpleValuePicker datasource available with the Extension Library.
