SharePoint 2010 - Content Query Web Part (CQWP) Slow Loading New Items?

We've recently implemented several Content Query Web Parts (CQWP) which I love. However, I noticed that new items weren't showing up so quickly. I did a couple of quick checks to make sure items weren't checked out or unapproved but to no avail.

Then, after some digging, I came across the following article from Michael Nemtsev: Why Content Query Web Part (CQWP) doesn’t return all results.

The workaround is a simple one:
set “UseCache” property to “false”.

Interesting note from the SharePoint Team:

Cite from SharePoint Team:

“You are only seeing your items in edit mode because the caching infrastructure of the CQWP does not cache checked-out items of individual users and we disable cache in edit mode. You can disable caching on your Web Part by setting the "UseCache" property to false”

Just a handy note in case anyone else has trouble with that very useful (but sometimes pesky) Content Query Web Part.

SharePoint 2010 Modal Dialog Window / Popup & XSLT Examples

Just wanted to share some of my XSLT snippets to create SharePoint 2010 modal dialog window / popups.

You can find some great info on Modal Windows here:

Also check out PAGETYPE Enumeration:

Here is a basic example of how to launch the Modal Window:

Now, some XSLT snippets for a discussion list view / toolbar

// New Form for Discussions

javascript:NewItem2(event,'../_layouts/listform.aspx?PageType=8&ListID={}&RootFolder=&ContentTypeId=0x0107&DiscussionParentId=');javascript:return false;

../_layouts/listform.aspx?PageType=8&ListID={}&RootFolder=&ContentTypeId=0x0107&DiscussionParentId=

 Reply 

// Edit Form

javascript:NewItem2(event,'../_layouts/listform.aspx?PageType=6&ListId={}&ID=');javascript:return false;

../_layouts/listform.aspx?PageType=6&ListId={}&ID=

 Edit 

// Display form to view attachments


javascript:NewItem2(event,'../_layouts/listform.aspx?PageType=4&ListId={}&ID=');javascript:return false;

../_layouts/listform.aspx?PageType=4&ListId={}&ID=

Assembly Development vs Artifact Development in SharePoint / Usage of SharePoint Designer in Production

This has been a hot topic for me recently. This article explains how SharePoint Designer can and should be used in a production environment by explaining Assembly Development vs Artifact Development or "Content" Development.

Team-Based Development in Microsoft Office SharePoint Server 2007
http://msdn.microsoft.com/en-us/library/bb428899.aspx

Some key points:
- Content Developers can use SharePoint Designer to create and modify content

- Content Developers have the ability to modify the existing production environment and conduct publication using a content management path to the production Web Farm.

- The authoring environment can exist within the production environment

- From a team perspective, the shared authoring environment is more effective than individually separate authoring environments.

- SharePoint Designer artifacts do not need to be integrated with enterprise source control

- Enterprise source control (such as Team Foundation Server) should be used strictly for assembly development in a team environment, while the effort to integrate content management items into source control is not a supported process.

- Attempts to integrate items into enterprise source control that are considered SharePoint Designer content items and part of a content development require extensive workarounds involving manual processes and procedures.


"For content design and publication, a single authoring environment - in which multiple content developers can use SharePoint Designer to create and publish content - can simplify time spent in migrating content artifacts from separate environments into a production environment.
