Today we have a closer look at using LINQ and anonymous types and it's pros and cons. Consider the case where we want to obtain a subset of data instead of an entire persistent instance. For example, if we want to obtain the contact details of all Customers based in London we would use the following query var query = from c in scope.Extent<Customer>()                    where c.City.Equals("London")                    select new { c.City, c.Address, c.ContactName };   Notice the last line in the above query - select new { c.City, c.Address, c.ContactName } This line creates an anonymous type. Behind the scenes, at compile time, a very simple class is generated automatically. In this case, three...

It is official – Telerik RadControls for Silverlight3 are here with the latest 2009 Q2 SP1 release. We did our best to take advantage of all new and exciting features from the latest version of the platform. RadControls now offer a new theming mechanism and you can clearly see the difference when you open our demo examples in Blend. We also added support for .NET RIA Services for all data-bound Telerik Silverlight 3 controls. Check the codeless binding of RadgridView to DomainDataSource to see how it works. The next exciting additions are validation for all input controls and out of browser support so now you...

It is a great pleasure to announce our new product line - Telerik Extensions for ASP.NET MVC. As the name suggest we are building a new UI component suite targeting the ASP.NET MVC framework. The new product line will not be based on RadControls for ASP.NET Ajax nor will it depend on ASP.NET Ajax or ASP.NET WebForms. No page lifecycle, ScriptManager dependency, viewstate or postback . And did I mention that it would be FREE? Free and Open Source Telerik Extensions for ASP.NET MVC is available as an open source product under the Ms-PL license. For the first time Telerik will be releasing a free...

As we already mentioned last week, Telerik OpenAccess ORM manages two cache levels – one specific for each ObjectScope instance and another shared by all scopes. The shared cache is generally called the "2nd level cache" or the "L2 cache". Its main job is to hold copies of the database content in memory. The L2 cache is populated during read access and gives fast retrieval of commonly used objects. This could be extremely helpful in multithreaded applications, where every single thread has its own ObjectScope. In order to avoid too many calls from each scope to the relational server, the L2...

A lot of people requested this, so we've put all our efforts into it and even managed to finish it in time for the Q2 service pack that shipped just this Friday - download it if you haven't yet. Please hold on your dismay - deploying an ASP.NET application containing Telerik Reporting on a web host that requires Medium Trust permission level is now a reality. For those of you, who do not know what that means - you probably do not need it, but if you would like to know, check the following "ASP.NET Trust Levels and Policy Files" and "Use Medium Trust in ASP.NET 2.0" documents in MSDN. There...
