Are you running into this error on your ASP.NET AJAX enabled web site? Does it only happen on some machines or on some browsers? Here's how you can get to the bottom of it.
jQuery.carouFredSel is a plugin that turns any kind of HTML element into an infinite, circular carousel. It can scroll one or multiple items simultaneously, horizontal or vertical, automatically, by pressing buttons or keys on the keyboard.
EditableGrid is an open source Javascript library aimed at turning HTML tables into advanced editable components. It focuses on simplicity: only a few lines of code are required to get your first table up and running.
A special thing about the queries is that they can be handled either directly in the database on the data provider level or by the data manager tier. When the query is being resolved, the data manager tries to use its data providers first and resorts to a higher level (and slower) API in case of failure.
Sometimes it is required to get all Items in the database based on a given template. Iterating through the entire database may be a very expensive operation though.
However in this particular case, we can resort to the Link database. Link database is used by Sitecore to resolve all the linking issues - what referrers and what references the Item has. And if an item is based on a template, it also counts as a reference from the item to the template. The solution then is very simple: get all the referrers for a given template item.
