I was developing an input form for a search when I came across the need to allow the user to filter items using a date range. I had two input boxes where the user could enter a start and an end date. For some of the most common date ranges, I decided to create links that could be clicked to auto-populate the start/end date textboxes. For example, searching for items that were created last week or last month. Using JavaScript’s Date object, I was able to put together some nice examples.

If you’ve done any work with SharePoint and SPAuditEntry, you may have noticed the distinct lack of Create event. Instead, two Update events are created which means some extra processing is required.

Add this to the list of things every SharePoint developer should know (up there with disposing SPWebs and SPSites).

In general…

1. Don’t update SharePoint objects on a GET request
2. Call SPUtility.ValidateFormDigest() before anything on a POST request

Here are the two links to read:

• What you need to know about AllowUnsafeUpdates (Part 1)
• What you need to know about AllowUnsafeUpdates (Part 2)

Two identical custom lists with the same columns. The only difference is that one list has columns added using Site Columns and the other list had columns added directly to the list. The same? Not so much…

This post is about using a C# console app to update choice fields via SharePoint web services.  If you are looking for more information on how SharePoint web services can be called via JavaScript, check out my post on building a simple SharePoint AJAX app.

My problem started with a simple change to a site column. I had originally created a Country field with the following values:

• US
• Canada

After a change in requirements, the new values for the field were:

• Canada
• Germany
• Great Britain
• Ireland
• United States

After updating the site column, I then needed to update the hundreds of items in the list to use “United States” instead of “US”. Instead of updating hundreds of items manually, I decided to write a small web services console app. (I was also not able to update it in datasheet… due to content approval maybe???)

However, I quickly ran into problems when attempting to update the multi-select choice field.
