    Some tricks with MEF up the sleeve of RadRichTextBox for Silverlight

    In Q2 we introduced the first official version of RadRichTextBox for Silverlight. In this blog post we want to share with you one of the main principles which we have followed while developing our brand new rich text editor for Silverlight - total extensibility. One of the key features which we have included is the ability to import/export from/to various document formats. For the first release we have already included some of the most widely used formats, such as .html/.docx/.xaml/.txt and in the next releases there are still more to come. As MEF is a wonderful technology, we have built...

The GDR did fix a lot of memory leaks, however, it did not address all of them and there are still some...

    Getting Started with LightSwitch and OpenAccess &ndash; Part 3

    In my last blog we learned how to create an OpenAccess Domain Service that can be consumed by LightSwitch.  In this post we will continue down this path, and get the service loaded as a data source in a LightSwitch application. Adding the Service Our first task today is to add a LightSwitch Project to our solution. Do this through the standard “Add New Project” dialog.  You should see “LightSwitch” as one of the installed templates in the tree view on the left.  Select C#/VB, give the project a name, and click Ok.   Our solution explorer should now look like this:   Right click on “Data...

    Building a Data Warehouse Part II: Building a new schema

    [repost from Stephen Forte's Blog] In Part I: When to build your data warehouse we looked at when you should build your data warehouse and concluded that you should build it sooner rather than later to take advantage of reporting and view optimization. Today we will look at your options to build your data warehouse schema. When architecting a data warehouse, you have two basic options: build a flat “reporting” table for each operation you are performing, or build with BI/cubes in mind and implement a “star” or “snowflake” schema. Let’s take a quick look at the first option and then we will take a look at...
