Cannot find type 'Telerik.Windows.Controls.RadContextMenu'

[Greg]

Can anyone help with this error?

Cannot find type 'Telerik.Windows.Controls.RadContextMenu'

I get this error when attempting to load the form containing Telerik controls. It is looking for the RadDropDownButton.cs file in the InitializeComponent().

Is this an installation issue or a licensing issue? I'm currently evaluating the Telerik controls.

Hi,

 Do you have reference to our navigation assembly? 

Greetings,

Hello,

Yes, I have the following references
Telerik.Windows.Controls.Data, .Docking, .GridView, .Input, .Navigation,
Telerik.Windows.Data
Telerik.Windows.Themes.Vista

The error is at:     <telerik:RadDocking>

I have an example project with this same control and it works fine. Is there something I'm doing incorrect? My example project isn't a WPF USERCONTROL, could that be the difference?

I've examined the reference's and they are using the same paths as the example project that works.

This is my XAML file:

Hi Greg,

Could you please check if the Target framework of your application is Client Profile. If that is the case, may I ask you to choose the full .Net framework instead of Client Profile. 

The problem with Client Profile is fixed in our latest Internal Build.

All the best,
Milan

Hi Milan,

I am running .Net 3.5 framework not the 3.5 Client Profile. I tried installing the latest hotfix it had no impact. I uninstalled and reinstalled using the 419 build and it had no impact. I don't understand why this won't run. I've examined all of the references and they are all the same version number. I have a sample application that uses the same controls and it runs fine. However, my application throws an error. These are the differences that I can see between the two programs:

1) Mine is a UserControl the sample is a Window
<UserControl
  x:Class="OSPInSight.Common.Forms.PatchEditor"

vs

<Window x:Class="TelerikTesting.MainWindow"

2) The sample application contains an app.config file and my solution does not:
<?xml version="1.0"?>
<configuration>
<startup><supportedRuntime version="v2.0.50727"/></startup></configuration>

3) The sample application has an output type of Windows Application mine is a Class Library.

I also tried including a reference to Telerik in all the projects that called or otherwise accessed the form containing the Telerik controls. Even though these projects do not specifically use the controls. The error seems to be specific to not being able to find the Telerik.Windows.Controls.Navigation.RadContextMenu.

Hello Greg,

I may suggest you to open a support ticket . This will allow you to attach a zip with the project . We will be glad to have a look at it and find out what went wrong.  I believe this is the faster and easier way to have the issue resolved.

Sincerely,
Pavel Pavlov
