VS Toolbox RadControls for Silverlight

[Robert]

I installed the Telerik Rad Controls for Silverlight on my computer using the Windows Installer Package, and the controls do not appear in the Visual Studio 2008 Toolbox. 

Are additional steps required to place the Rad Controls for Silverlight in the Visual Studio 2008 Toolbox?

Thanks in advance! Rob

Hi Robert;

While your toolbox is active, right click and select "Choose Items".
From Dialog box, click on Silverlight tab
On SL page, click on Browse button, navigate to Telerik | RadControls For SL | Binaries | Silverlight and select the dll you need. Repeat for each dll.
They should then appear on the toolbox.

Hope this helps!

Which Telerik | RadControls For SL | Binaries | dll is necessary for the Cover Flow Control?

Best regards, Rob

Telerik.Windows.Controls.Dll
telerik.Windows.Controls.Navigation.Dll

Hi,

Even i have the same question.
And I tried to add the controls manually using "Choose Items" but I got the following error.

There was an error loading types from assembly 'C:\Program Files\Telerik\RadControls for Silverlight Q3 2008\Binaries\Silverlight\Telerik.Windows.Controls.dll'

'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.'

I have the installed the following
1. VS 2008 SP1
2. .NET Framework 3.5 SP1
3. Silverlight_Tools.exe
4. RadControls_for_Silverlight_2008_3_1217_TRIAL_Futures.msi

Thanks and regards
Sundar

I found the solution to this problem, it is due to the wrong tab i have selected while adding the dll. On selecting the "Silverlight Component" tab it worked.

Please refer to the below link
http://www.telerik.com/support/kb/silverlight/general/how-to-manually-install-the-telerik-radcontrols-for-silverlight-2-ctp-tools.aspx

But, I am facing another problem, even I have added the Telerik controls to the Toolbox, i am not able to see the controls in the preview pane in VS 2008. It says, 

Error HRESULT E_FAIL has been returned from a call to a COM component.

Any help would be great.

Thanks and regards

Hello Sundar,

Could you please check whether you are trying to add the assemblies to the Silverlight tab. Please, check the attached screenshot.

Hi Miroslav Nedyalkov,

Thanks for your response.
If you could check my last post i have mentioned that, the problem of adding the controls to the VS Toolbox is solved by adding it in the "Silverlight component" tab. Exactly as you mentioned. But my other problem is I am not able to view the controls in the preview pane. The error message is mentioned in my previous post.

Hello Sundar,

It appeared that you were sending your solution while I was writing my reply.

About the new problem - this error is thrown when the project doesn't have a reference to the Telerik.Windows.Data assembly. The  references to the controls' assemblies are automatically added by the designer, but the reference to this one (Telerik.Windows.Data) is not. Simply add it and the problem should disappear.

Hope this helps.

Hi Miroslav Nedyalkov ,

Thanks for your reply.
As per your suggestion, i have added the assembly reference to the Page.xaml file like below

 

 

<UserControl ...

 

 

xmlns

 

:telerikData="clr-namespace:Telerik.Windows.Data;assembly=Telerik.Windows.Data"

 

</UserControl>

but still i have the same error message displayed in the preview pane.

Thanks
Sundar

[Ben Hayat]

Sundar, did you add Telerik.Windows.Data to your project?

Hello Sundar,

Unfortunately, the problem is not only in the reference. The following post explains the other problem:

RadControl for Silverlight 2009_2_701_Dev

I had no problems installing its cousins the telerik controls for aspnet ajax controls worked like a charm!

can someone let me know if there is a way of solving this. I even went as far as to uninstall the telerik for silverlight and re-install them and re-tried but to no avail! Grrrrrrrrrr!!! Frustrating!

[Kingsley Magnus-Eweka]

Hi All,
Finally figured it out i was using silverlight 2 SDK instead of silverlight 3SDK hence the references were unresolvable when accessing the controls.

Hi Kingsley,

I'm glad that you were able to resolve the issue yourself.

Once I had the same issue and Reset on the ToolBox brought back the RadControl group. Strange #^#*#!

[Gary Paul]

I applied the December 2011 update and now my Toolbox is very messed up. Graphically there are odd lines in it and I can't select an item visually however I can drag from the tool box to my UserControl and get a random object!
I have rebooted my machine and also tried the Telerik\RadControls for Silverlight\Launch Toolbox Configurater to no avail!

Hi Gary,

Did you try Resetting theTtoolbox (right-click the Toolbox and hit "Reset")?
