Telerik announced today that RadControls for Silverlight 4 CTP is the first UI component suite to natively support Microsoft Silverlight 4 Beta and to provide support for the right mouse click feature introduced with the latest Microsoft Silverlight release.

The Silverlight 4 Beta version delivers powerful capabilities to business application developers strengthening its position as the number one choice for building business applications on the Web.

RadControls ensure that developers can use RadControls for Silverlight 4 with the latest Silverlight version and start building their applications today.

With the Silverlight 4 Beta release Microsoft announced support for conventional desktop interaction models through new features such as right-click context menu. RadControls for Silverlight 4 now benefit from this new addition and allow you to use RadContextMenu without enabling windowless mode.

Note: This CTP version of RadControls for Silverlight 4 does not provide Toolbox support in VS 2010 Beta.

The RadControls for Silverlight 4 assemblies are available as a single ZIP download under the users' accounts at:

Hey all,

In case anyone is as slow as I am on a Monday morning, one quick tip to get you playing with the Silverlight 4 goodness we've just put out.

When you download the zip file for the SL4 build, be sure to right click on it and unblock the file. Then extract it and feel free to add references to the assemblies from the folder you extracted to. If you don't do this, you'll get a friendly VS2010 error message about unable to load remote assemblies, etc..

Otherwise, I'm happy to say I'm going back and forth between this response and my VS2010 installation and playing with the controls now and everything is working great!

(P.S.- This is the same note I put on the blog post, just figured some people might hit the forum and see this first so I wanted to put this here, too!)

Hey Jim,

If you go to Trials, then under the RadControls for Silverlight main download link there should be another link that reads:

"Silverlight 4 Build, DLLs, Source Code, Automatic Installation..."

When you go to this, it should be the last download available in the list. If you're logged in, see if this direct link to the trial download works for you:

http://www.telerik.com/downloads.aspx?fileid=10057&dispkey=True

And to answer your question, this does fix that issue, however there is currently not toolbox support (as mentioned in this forum/related blog post). So you can use this newest CTP in your SL4 project, but you'll have to get your hands dirty a tiny bit by writing the XAML for the controls by hand. Otherwise, for working with SL3 in VS2010, you'd want to use the Q3 2009 SP1 release (and use the automatic installation).

Greetings!

After switching to the SL4 build, I now get the following error during the InitializeComponent event of a user control that has the RadOutlookBar on it. The RadOutlookBar has no items declared in the .xaml as I'm adding them programmatically.

It works fine when I switch the references back to the SL3 components.

Thanks!
Lee

I just downloaded the silverlight 4 CTP, got the following compilation error. any idea?

Hi Evan,

It appears that the error only occurs when the RadOutlookBar is inside of a RadDocking\RadSplitContainer. Much like this:

    
            <telerikDocking:RadDocking x:Name="docking">  
        
                    <telerikDocking:RadSplitContainer InitialPosition="DockedLeft">  
        
                            <telerikDocking:RadPaneGroup> 
        
                                    <telerikDocking:RadPane CanFloat="False" Padding="0" CanUserClose="False" Header="Environments">  
        
                                        <telerikNavigation:RadOutlookBar x:Name="obEnvironments" Padding="15">  
        
                                        </telerikNavigation:RadOutlookBar> 
        
                                    </telerikDocking:RadPane> 
        
                            </telerikDocking:RadPaneGroup> 
        
                        </telerikDocking:RadSplitContainer> 
        
                        <telerikDocking:RadDocking.DocumentHost> 
        
                            <telerikDocking:RadSplitContainer> 
        
                                <telerikDocking:RadPaneGroup> 
        
                                    <telerikDocking:RadPane CanUserClose="False">  
        
                                    </telerikDocking:RadPane> 
        
                                </telerikDocking:RadPaneGroup> 
        
                            </telerikDocking:RadSplitContainer>

Hi all,

We will be uploading RadControls for Silverlight 4 assemblies as soon as Microsoft officially announce the next Silverlight 4 version. We expect this announcement these days. Right after that we will blog about the availability of RadControls for Silverlight 4 built against the latest Silverlight official version. If it happens that you are attending MIX in Las Vegas right now you can check our booth for more details and demos. Otherwise keep an eye on blogs.telerik.com.

Sincerely yours,
Nick

After downloading the RadControls for Silverlight 4 and copying them to the VS Public Assemblies folder I get the following error when I try to complie a VS2010 SL4 program in which I have included the RadGridView Control

Error 1 Could not load file or assembly
'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies.
The system cannot find the file specified.

When I remove the RadGridView and delete all references to Telerik assemblies the program will compile successfully.

The error shown above is repeated for all the xaml files.

The reference to System.Windows shows a Version of 2.0.5.0 in the property viewer.
Is it possible that the PublicKeyToken referenced in the above message is not the same as the PublicKeyToken in
c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0\System.Windows.dll?

I added the RadGridView to the toolbox and dragged it onto the designer to produce the results outlined above.

Other Telerik RadControls for SL4 produce the same result.

Any suggestions on how to solve this would be appreciated.

Hello Mark McPherson,

First of all are you sure that you have created SL4 project and not SL3 as usually you are getting the exact same error in this case. Also do you have our SL3 controls installed on the machine? There is some conflict when you have our SL3 controls installed and trying to use our SL4 assemblies and the error was similar.

Hope this helps. If the problem is still there please let me know and some info about VS 2010 version would be of help, is it RC or Beta2 etc.

Boyan
