RadRibbonView - Setting IsMinimized in Style causing InvalidOperationException

[Brian]

GOAL: Have the Ribbon start minimized or settable from my VM using state.

The RadRibbonView is bound to a RadRichTextBox. I pretty much used the sample app for the template.

I set the IsMinimized in the template and it crashed.

Then I tried a style.

<Style TargetType="{x:Type telerik:RadRichTextBoxRibbonUI}" BasedOn="{StaticResource {x:Type telerik:RadRichTextBoxRibbonUI}}">
        <Setter Property="IsMinimized" Value="true"/>
    </Style>


Failed.

Here is the crash.

Hi,

I tried to reproduce the reported behavior on our side with our latest official release and it seems that the code works as expected. Could you please take a look at the attached project and let me know if I missed something?

Thanks.

Your demo helped me to search further. I ended up finding out it was due to me loading your controls in a splash screen to minimize the load time in the application(front loading). If I closed the splash screen too fast, your control threw exceptions. I put in a delay to make the load time a couple of seconds and it worked.

Makes me wonder if your control will fail on any windows that are launched then very quickly dismissed.

Anyway, I found a work around.
