RadRibbonWindow Title Bar

[Jason]

I am building a prototype using a RadRibbonWindow as a main application window with a RadRibbonView.  There is a vertical line that is always on the title bar that I would like to get rid of but I can't seem to locate any way to do it.  If you look close at the attached screenshot it is behind the circular application icon.  Is there a style associated with it?  I am currently using the latest Q3 2012 build (trial edition).

I also attached a 2nd image from a sample application I downloaded from these forums that shows it more clearly.

Hi Jason,

The separator line is placed there to separate the WindowIcon from the header content of the RadRibbonWindow. Once you set he RadRibbonWindow Icon propety, a drop down menu allowing you to modify the window(Restore/Minimize/Maximize/Move) will be display when you click the Icon.
In order to hide the separator you could set the RadRibbonView WindowIconVisibility property to Collapsed and the separator will disappear, however you will not be able to use the modify drop down menu.

I hope this information helps, please do not hesitate to ask any further questions.

All the best,

I am currently running into the same problem right now.  If I change my WindowIconVisibility to Hidden or Collapsed I get an error, but not when I use Visible: "Value cannot be null. Parameter name: dp".  I cannot build or rebuild my solution, so I can't Run it either.  Here is my code, the error is on Line 5, Column 25 (The entire WindowIconVisibility="Hidden" is underlined):

<telerik:RadRibbonWindow xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                         xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                         x:Class="Project.MainWindow">
    <telerik:RadRibbonView WindowIconVisibility="Hidden">

    </telerik:RadRibbonView>
</telerik:RadRibbonWindow>

I am using the most recent Q3 2012 full version. 

Here is my unhandled exception information:
