The feedback about our new version of CoverFlow for Silverlight has been great! Thank you guys for pointing out all these small issues and problems that had to be polished since we introduced a new beta CoverFlow for Silverlight 3 back in September. After the core functionality of the control is successfully integrated in our Silverlight 3 suite, we are now able to start developing new features that every grown-up CoverFlow control should possess :)

Vertical Orientation

    Both in our forum and support system we have received numerous requests for vertical orientation of the CoverFlow control. That is why, with our 2009...

Sometimes when using a Docking control and implementing complex UI with it we need to add some custom rules about allowing some panes to be docked in some parts of the application and to disallow them to dock to other parts. As this behavior is quite complex itself, we’ve decided to enable some scenarios to be available in XAML in a declarative way (the more static scenarios) and some scenarios to be available only through the code-behind.
 
In this post I will guide you through some simple steps that will show you how you could use both approaches. First of all...

Using FixedDocument, DocumentViewer and PrintDialog you can easily create your own print and/or print preview for RadGridView for WPF.

I’ve made two extension methods Print() and PrintPreview() to illustrate how to turn the grid into a print friendly document in few lines of code:
…

public static void PrintPreview(this GridViewDataControl source)
{
    var window = new Window()
    {
        Title = "Print Preview",
        Content = new DocumentViewer()
     ...

With the introduction of LINQ the concept of querying data became a first-class language construct in C# and Visual Basic.  LINQ enables to you write type-safe queries which are checked during compile-time. While type-safe queries are fine for certain situations, there might be cases where you want to construct a query on the fly, at runtime, based on certain selections made by the user. This is usually done using a string-based representation of the query. How can this be achieved via LINQ?

The LINQ team at Microsoft provides the Dynamic Query Library which extends the core LINQ API with capability to use...

One of the less known features supported by Telerik’s RadChart for Silverlight/WPF is the ability to completely abandon the default control layout and build one of your own with no constraints for the number of elements used. The goal of this blog post is to shed some light on this functionality and to demonstrate the most common techniques that can be used to customize the legend.

First of all, to build your own custom chart layout you should set the UseDefaultLayout property of the RadChart object to false. Here is the custom layout I prepared:

With the release of RadControls for ASP.NET Ajax Q3 2009 SP1 we introduced built-in CDN support. It was very logical that Telerik Extensions for ASP.NET MVC receive some CDN love as well. Now this is a fact! Go download the current release from here (open source) or here (licensed).

Enabling global CDN support from web.config

Add the following XML in your web.config:

<configSections>
 <sectionGroup name="telerik">
 <section name="webAssets" type="Telerik.Web.Mvc.Configuration.WebAssetConfigurationSection, Telerik.Web.Mvc"/>
 </sectionGroup>
</configSections>
<telerik>
 <webAssets useTelerikContentDeliveryNetwork="true" />
</telerik>

Enable CDN support from code

Html.Telerik().ScriptRegistrar()
    .DefaultGroup(group => group.UseTelerikContentDeliveryNetwork(true))

We just uploaded a video produced by Sahil Malik, a Microsoft MVP and INETA speaker. This video shows how to use Telerik Silverlight controls in SharePoint 2010. The approach demonstrated in this video is Telerik Silverlight controls working with the client object model, in particular RadScheduler talking to the Calendar list.

For more details you can also check Sahil's blogpost at:

When you don't blog regularly, one of the biggest challenges is to find a good topic. With Twitter around, it becomes even more complicated for the people that are not regular bloggers. While I was waiting for something interesting to pop-up as a topic, 2009 almost passed and it gave me the needed opportunity. It feels as if I blinked and it's Christmas Season again.
 
Before I move on with my overview, on behalf of everyone at Telerik, I would like to wish you and your families a better 2010 – stay healthy, happy and lucky. Thank you for being a part of the...

While performing regular reviews of Telerik support communication, I come upon the following question which appears to be asked every so often:

'What support channel should I be using for my development questions?'

As this is something that may bother each of us at some point, I decided to uncover the veil and provide some direction as well as a short list of pros and cons of each option.

The two main routes you can take to get assistance from the Telerik Support Staff are pretty well-known: posting an inquiry in the Telerik public forum or creating a support ticket. It...

I’m pleased to announce that with our upcoming service pack (Q3 SP2 – middle of January 2010) you will be able to plug your own scrolling logic for RadGridView for Silverlight. I’ve made small demo on how to page DomainDataSource using the grid vertical scrollbar with minimal coding effort:

 

…

<riaControls:DomainDataSource x:Name="DomainDataSource1" QueryName="GetOrder_Details">
    <riaControls:DomainDataSource.DomainContext>
        <web:NorthwindDomainContext />
    </riaControls:DomainDataSource.DomainContext>
</riaControls:DomainDataSource>
<telerikGridView:RadGridView telerik:Theming.Theme="Summer" 
 scrolling:CustomScrolling.DomainDataSource="{Binding ElementName=DomainDataSource1}"
 ItemsSource="{Binding Data, ElementName=DomainDataSource1}" 
 IsBusy="{Binding IsLoadingData, ElementName=DomainDataSource1}"...
