    How to: Validate data with SL/WPF RadGridView Part I – validating on property/cell level via Data Annotations

    With the next Q3 2009 official release we are introducing a significant improvement to the validation mechanism of the RadGridView control. If we compare the new validation to the previous versions we add another validation layer (Data Layer) and refactoring of the related events. In a series of blog posts I’ll try to clarify this mechanism with several small examples. I’ll start the series with validation for a single cell.   How to: Validate data on a cell (property) level with RadGridView for Silverlight and WPF   The cell validation occurs when a GridViewCell is edited and its new data is about to be committed.

Whenever Telerik puts something up on Telerik Labs we hope that some early adopters will try it out and give us feedback.

    Upgrade Wizard: auto-upgrades and more

    Developers (yours truly included) often hate it when there is a need to deal with an external tool to accomplish a simple task. The upgrade process of RadControls seems such a task – you need to start a browser, open the Telerik website, login to your account, navigate to the Downloads section, download the installer and run it. Even more - if you want to keep updated you need to either check your RSS reader or e-mail, or refresh the Downloads page when you’re eagerly waiting for a new version.   One of the new features in the RadControls for ASP.NET...

    How to display data from different tables using one data source

    In many cases our customers that use Telerik OpenAccess ORM face the need to rapidly change the source table from which they are displaying data. For example you can have a RadGrid filled with customers on the start of your application and whenever a certain customer is selected you can change the displayed data in the grid with the Orders for the given customer (note that in such case the data will be taken from two different tables – Customers and Orders). But do you need two datasource controls to do this? The simple answer is NO. You can achieve this...

    The references in the object model and the references in the database schema can be defined in several ways. The definitions are following different idioms and it is not straight forward how a mapping can be defined. In the database schema you have the foreign key reference; in the object model you have single references, collections and dictionaries. Let’s look at a simple schema in the database, the Persons table has a foreign key reference to the Addresses table. There are now 3 ways to map this in OpenAccess. 1. You can map it to a reference field which is the...
