Tag: SharePoint

Today I am trying to populate an ASP.Net drop down list from the contents of a SharePoint list using the Lists web service.

I found this Microsoft page that was most useful in helping me to do that: http://msdn.microsoft.com/en-us/library/lists.lists.getlistitems.aspx

A couple of issues I struck that are mentioned in the article:

• I was getting a SOAP error saying “Guid should contain 32 digits with 4 dashes”. As mentioned in the above article this is due to Visual Studio putting a web reference in Web.config to the top level site rather than the sub-site in which the list exists.
• Once the above was fixed, I got a second error: “InvalidOperationException: Client found response content type of ‘text/html; charset=utf-8’, but expected ‘text/xml’”.

Users requested that I filter a list of announcements so that the logic would work like:

(Show All Users Notices OR Staff Notices) AND (Posted before today AND expire after today).

The default filtering doesn’t let you put the brackets into the filter query. Turns out that SharePoint runs the query in order and ‘virtually’ puts brackets around things.

So my eventual logic was(((Show all Users Notices Or Staff Notices) AND StartDate before Today) AND Expires After Today).…
