XAML editor complains “Object does not match target type” while using the RibbonView. I have the latest updated VS2017.

I have tried using the threads on StackOverflow.

https://stackoverflow.com/questions/14591781/object-does-not-match-target-type

https://stackoverflow.com/questions/31815177/design-mode-error-object-does-not-match-target-type-for-loaded-page-resource

https://stackoverflow.com/questions/31726759/xaml-editor-complains-object-does-not-match-target-type-for-sharedresourcedict

I was not able to resolve my error using them links. The source compiles and runs but the editor complains and it is irritating and obstructing actual errors.

Hello,

I ran the snippet in VS2017 Professional without success of reproducing the issue. Could I ask you to provide a runnable sample project that isolates the issue, since I assume that clearing all the bindings and static setters might have prevented the issue from occurring).

Furthermore, I could suggest closing the studio, cleaning the bin and obj folders and their contents, and rebuilding, and/or checking if the types of the static properties that are set to the controls meet the expected types for the properties - i.e. if the Title of the RadRibbonView is a string etc.

Martin
