Hi, I'm having similar issue with WPF application. I have updated all telerik products today (Q3 2013 SP1)

[Daní]

After closing and launching Visual Studio again error disappeared, however, at runtime I'm getting following exception:

A first chance exception of type 'System.IO.FileLoadException' occurred in Telerik.ReportViewer.Wpf.dll

Additional information: Could not load file or assembly 'Telerik.Windows.Controls, Version=2013.3.1016.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

It looks like Telerik.ReportViewer.WPF.dll depends on Telerik.Windows.Controls dll targeting .Net 4.0. My application targets .Net 4.5 framework and current Telerik's dlls version i'm using is 2013.3.1016.45.

Hello,

@Dani: For each major Q release the WPF ReportViewer is built against the WPF assemblies shipped with our local demos(the major version for the Q of the UI for WPF suite), so it can be used even without purchased Telerik UI for WPF suite.
If you have both products and intend to use greater version of the WPF assemblies, you need to add binding redirects as illustrated in the How to: Add report viewer to a WPF application help article.

@KAROUI: Please test to run the UI for Silverlight Upgrade Wizard and verify there are no left references to Silverlight version 2013.2.611.1050.

I have redirect all assemblies as shown above. 
However, when i tried to drag and drop the ReportViewer control to the User Control, this error message appear:
Cannot create an instance of "ReportViewer". (see attach picture).

I have installed Telerik Reporting Q3 2013 SP1 version 7.2.14.127

Have i missed out anything?

Hi Joel,

Note that these are run-time settings and VS2010 fails to recognize them at design-time. If this is not the case, check if the project where the viewer is used has applied binding redirects. If you are using VS 2013, you can use the new Automatic Binding Redirection feature.

I am not quite sure what you mean by "Note that these are run-time settings and VS2010 fails to recognize them at design-time"
I am using VS2010. 
Here is what happen:
1) I have created a skeleton WPF project.
2) Add the binding redirect in App.Config.
3) Drag and Drop the Report Viewer from the toolbox to MainWindow.xaml. 
4) It throws the error i mentioned above.

[Stef]

Hello Joel,

This is a known issue with Vs2010 logged in our system for investigation. Running the project with the applied assembly redirection will not cause the error.

You can also switch to VS2012+, where the designer loads the viewer correctly.

Hi Stef,

  You said this is a known issue with VS2010 and yet at the same time mention "Running the project with the applied assembly redirection WILL NOT cause the error."
  Have i done something or this is a known issue?

  Bottom line is i must be able to drag & drop the ReportViewer into the xaml desinger page.
  Unfortunately i am not switching to other VS version anytime soon.
  
  As of this writing, i am downloading the latest Q1 2014 update. Keeping my finger cross it will eventually works.

Hello Joel,

Dragging and dropping the Report Viewer into the XAML designer window in Visual Studio 2010 will cause the described error. This is a known issue and is already logged in our system for further investigation and improvement.

Although you may not be able to drag and drop the Report Viewer into the XAML designer in VS2010, you can achieve the same result by manually inserting the required XAML code to add the viewer to the WPF window. For additional details please refer to the code snippets in the How to: Add report viewer to a WPF application help article, and the examples installed on your machine inside C:\Program Files (x86)\Telerik\Reporting <version>\Examples.

Unfortunately it is still not working. 
I receive a "Cannot create an instance of ReportViewer" error message.

Could not load file or assembly 'Telerik.Windows.Controls, Version=2013.3.1202.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified.

   at Telerik.ReportViewer.Wpf.ReportViewer..cctor()

Please see screenshot.

Hello, 

i have the same Problem. How can i solve it?

[Nasko]

Hello Dieter,

If the provided suggestions earlier in this thread do not help you may try to install the latest internal build of Telerik Reporting (Q1 2014, version 8.0.14.311), which is built against UI for WPF Q1 2014. Then with UI for WPF Q1 2014 you won't need to use binding redirects and you will be able to copy all of the needed resources for the viewer directly from the C:\Program Files (x86)\Telerik\Reporting Q1 2014\Wpf\Themes folder and the viewer should work correctly.

In case the Report Viewer shows a blank window please follow the The WPF/Silverlight report viewer is blank after upgrading from version prior to Q1 2014 to Q1 2014 or later KB article.

Nasko

Hi there, I'm also facing the same problem with the original poster, but I'm using  VS2012. So are there any official fix/work around on this issue?

[KS]

Hi,

Run the Upgrade Wizard for Reporting and SL and see if versions are synchronized.
How to: Add report viewer to a Silverlight application

-KS

[Fredi]

Hi there KS, 
The version are synced up yesterday.

I tried to follow that tutorial, but I got stuck with the attached error. 

Any idea? I've been stuck for 24 hours now

[Stef]

Hello Fredi,

The error indicates mismatch in the used XAML files and NoXAML binaries in the project.

If Telerik Reporting and Telerik UI for Silverlight assemblies versions are synchronized at your side. Please double-check if the Telerik.ReportViewer.Silverlight.xaml is updated from the Telerik Reporting product folder, and the rest XAML files are taken from the Telerik UI for Silverlight product folder for the referenced versions of the product.

For more details, please test the solution described in the http://www.telerik.com/support/kb/reporting/details/the-wpf-silverlight-report-viewer-is-blank-after-upgrading-from-version-prior-to-q1-2014-to-q1-2014-or-later KB article.

If you need further help, feel free to open a support ticket and send us the problematic project to check its settings.

Stef

Now I need to Install same version Report Viewer tool to modify some report but I am not able to download same trail Version. Once I am trying from Internet, "Telerik_Reporting_Trial_Installer_Q2_2015" will Install every time. please help me on this. I am in the process to get the Telerik License, so Please let me know if we get the license then we can download and Install previous version or we should Upgrade the application with Latest telerik Reporting DLL's .

 

Kindly help to provide this Information.

[Nasko]

Hello AMIT,

The trial version of Telerik Reporting is used for demonstration and test purposes only. Thus, we provide only the latest version for download.
Once you obtain a valid Telerik Reporting license, you will be able to download previous versions of Telerik Reporting, including Q3 2013 SP1.

In case you decide to modify older reports with the latest version of Telerik Reporting, you will need to run the Upgrade Wizard first to upgrade all of the reports and project references to the latest version.
