RadRibbonBar: Setting the RadDropDownListElement.DropDownAnimationEnabled breaks the designer
I am using the Winforms 4.8 Nuget package. And just recently now when I make any edits to the form with a RadRibbonBar in the designer, the declare for that object in the designer.cs code changes from RadRibbonBar to DropDownPopupForm.

Thanks for reporting the issue. It seems to be caused by the RadDropDownListElement.DropDownAnimationEnabled property. Here are simplified repro steps:

  1. Add a ribbonbar to a form. In some group add a RadDropDownListElement.
  2. Select the drop-down list element and set its DropDownAnimationEnabled to false or simply reset it. 
  3. Close and open the designer.
  4. Change something so that the form serializes.
  5. The project won't build.


Don't set the RadDropDownListElement.DropDownAnimationEnabled property in the designer and set it at runtime.
