I just created a RadRibbonWindow in my application, each time I called this window,the program was interupted. 

Picture of exception is in attachment.


These are my codes in xaml:

<telerik:RadRibbonWindow x:Class="AutoTerminalFunction.Views.RadRibbonTest"
        <telerik:RadRibbonView Title="RibbonView Title" ApplicationName="My Application">
                    <telerik:RadRibbonButton Text="Option 1" />
            <telerik:RadRibbonTab Header="Home">
                <telerik:RadRibbonGroup Header="Clipboard">
                    <telerik:RadRibbonSplitButton Size="Large" 
                                                  telerik:ScreenTip.Description="Paste the contents the Clipboard." 
                            <telerik:RadContextMenu BorderThickness="0">
                                <telerik:RadMenuItem Header="Paste" />
                                <telerik:RadMenuItem Header="Paste Form" />
            <telerik:RadRibbonTab Header="View" />


Backstage codes are original.


Does anyone know what causes this problem?I've tried everything I know,like remove and re-referencingTelerik.WIndows.Controls.Input.dll.

Thanks alot!

Hello Sean,

This type of error appears if there is a mix up between the versions of the referenced Telerik dlls. You will need to ensure that all Telerik assemblies have the same version. For example 2022.2.511. After that you can manually delete the bin and obj folders of the project in order to avoid any cache. And then Clean/Rebuild the project. 

Additionally, this exception is the last one from 3 exceptions. If the previous steps don't help can you send over also the other 2 exceptions? Moreover, a sample project reproducing this will be very useful.

Hello Martin,

Thanks for your help, I've removed bin and obj folders and rebuilt the project, and the other two exceptions has been resolved, but I still get the "Could not load file or assembly" exception.

Any other suggestions? Thanks.

You can double check if you have a reference to the Telerik.Windows.Controls.RibbonView assembly. If so, then you can send over the troublesome project here and I will take a look.

Finally I've found some caches of other version somewhere, problem solved.

Thank you so much Martin, you suggestion is right.
