SharePoint 2010 Content Query Web Part with paging

One of the coolest and probably most frequently used Web Parts in SharePoint 2007 was the Content Query Web Part (CQWP) – a great control that allowed you to display content aggregations to the users. Although it was pretty awesome, it had some serious drawbacks like for example the lack of a paging mechanism – something that almost every single Web Content Management project that I worked on required. Three years later in SharePoint 2010 the CQWP got a facelift and shipped with some seriously cool features like slots and the Content to Content concept. Unfortunately still no sign of paging. So what if you want to create an aggregation of your content and page the contents? Do you have to create a custom and bad performing Web Part? Not really… Introducing Imtech Content Query Web Part v14!

Overloading functions in JavaScript

If you are a SharePoint developer, or do some general .NET development, you probably work with overloading methods. Using the same name you can define multiple variants of the same method by specifying a different set of parameters. As SharePoint 2010 contains a large piece of very powerful API in the JavaScript: both for communicating with the SharePoint platform (also known as the SharePoint Client Object Model) and manipulating the UI, the odds are high that you will sooner or later start using JavaScript more and will extend the functionality provided by SharePoint to meet your needs. While overloading might seem very straight forward, there is one thing that you need to remember while working with JavaScript.

Filling forms using data from EntityPicker aka EntityPicker with Callback

Windows SharePoint Services v3 ships with many controls that simplify entering data. One of such controls is the EntityPicker which allows users to search for data and then select the desired record(s). Not only is the EntityPicker very intuitive but also highly extensible. Did you know that you can extend the EntityPicker to make it fill the list form using the data from the entity that you picked?
