I have a requirement that a SPList should be sorted by the Priority field

  • 0

I have a requirement that a SPList should be sorted by the “Priority” field (number field, no limits) when a ListItem is added or updated.

The sort should work as this:

Original        Inserted item         Modified
   1                                      1
   2                2                     2
   3                                      3 (old 2)
                                          4 (old 3)

Edited: This behaviour is primary for improving the user experience when editing data in the data sheet view.
It is a sort of a poor mans AJAX style updates that I am trying to get.

The only solution I see right now is to use an event handler and update the ListItems that should be deprioritized, however that could be a fairly costly operation on a list with hundreds of items (unless there are gaps in the sequence).

Have I missed the obvious solution, or a far better scaling way?

    Wow, tough one. I do not like the idea of going back and doing updates to existing items from a EventReceiver. You are asking for trouble.

    Here is my recomendation.

    Use 2 fields for your sort.

    1 your priorty field as you have it today (so someone says 1, 2 , 3, 4)…
    2 the create date field (this is a builtin datetime field).

    so your results would look something like this

    1 1/1/2009
    2 5/16/2009
    2 5/11/2009
    3 5/12/2009
