Task-It Series This post is part of a series of blog posts and videos about the Task-It (task management) application that I have been building with Silverlight 4 and Telerik's RadControls for Silverlight 4. For a full index of these resources, please go here. One of the posts listed in the index provides a full source download for the application, and I will be referring to that source code in this post. The page state issue One of the great things about MEF is that it allows you to maintain state across pages. So basically, when a user spends some time on a page and makes some changes, then...

As we all know Q1 introduced a complete new face of OpenAccess ORM. That of course brought some uncertainties between our older customers that had already built their projects based on models generated by the Reverse Mapping Wizard.

The Q2 release is finally here and I am excited to talk about some of the changes in one of the newer controls in the RadControls for ASP.NET AJAX Suite – the RadAsyncUpload. If you browse the live demos, you may not notice any differences immediately, but that’s simply because most of the changes are under the hood. Let’s have a look… First the most important new feature, seen above – Multiple file selection! RadAsyncUpload now allows users to select multiple files at once in the File Selection dialog which is very handy in scenarios where uploading a large number of...
