Yesterday I showed you a neat way to hide/show some content based on authentication level and/or the page mode. The cool thing about it was that whenever the control was hidden, the child controls didn’t get instantiated at all preventing you from any kind of performance penalty. Today, when I read the article myself, it struck me: you could extract a piece of the control that I showed you yesterday and make of it a base class for all kind of conditionally visible content like content visible based on a query string parameter or a value of a field of the current page!
About a year ago I wrote about the inconvenience of the SPSecurityTrimmedControl: a great idea within the SharePoint framework that unfortunately doesn’t work the way it should. Now, as we’re about to get a new release of SharePoint, I decided to check if things have changed.
Body id is a cool webdesign trick that allows designers to easily alter the layout of a page using nothing more than a single property and some CSS styling. Using the body id you can define one HTML page structure for the whole site and then, by changing the single value of the body id attribute, you can create new experiences by styling the different pieces of the page in a totally different way. While it sounds very easy and it is very easy with HTML, this trick can get very challenging when used with SharePoint.
Visual Studio 2010 ships with new SharePoint Developer Tools that simplify the process of developing solutions for the SharePoint platform. Using nothing more than the standard functionality provided with the tools you can rapidly create custom solution by focusing on the real work instead of the plumbing. There are however things that you still have to do by hand.
Recently I published a new extended version of the Content Query Web Part. I extended the SharePoint 2010 version of CQWP with support for paging the results which is one of the things that our customers ask for very often. But that’s not the end of the extensibility possibilities of the CQWP. In this version I extended the Imtech Content Query Web Part even further by adding additional capabilities which make working with the CQWP even easier. Introducing: Imtech Content Query Web Part v14.2!
