1. Change the theme to FluentDark using the dropdown located at the very top left of the app form (it should say Fluent as default). 
2. Select the Administration View ribbon group, located at the very left of the form ribbon
3. Select any option from the dropdown menu that appears 
You should see that the borders around the ribbon groups appear, and  once the mouse hovers over a collection is 'refreshes' them and the issue is then not repeatable for that group of buttons (even after another theme change). As mentioned in the previous ticket, this issue is only repeatable once per application launch

Currently the Keytips in the Ribbonbar and cannot process some chars like "Ä", "Ü", "Ö" and "ß".

The keytips not activating after splash form is closed and alt key is pressed. For the keytips of RadRibbonBar to break, the splash form (or any other form that appears before the form containing RadRibbonBar) should contain a RadControl. The workaround is to unregister the shortcuts that the RadControl in the splash form has. For example: ChordMessageFilter.UnregisterChordsConsumer(this.radTitleBar1.Behavior.Shortcuts); This line assumes that there is a RadTitleBar on the splash form.

It will be nice if RadRibbonBar has the QuickAccessToolbar property exposed in the property grid of Visual Studio, just like ExpandButton, ExitButton, etc.

Metro theme for RadRibborBar has glitches for the application menu and quick access bar.

To Reproduce:
            this.AllowAero = false;
            this.radRibbonBar1.RibbonBarElement.RibbonCaption.MinimizeButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
            this.radRibbonBar1.RibbonBarElement.RibbonCaption.MaximizeButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

FIX. RadRibbonForm - theme is not applying correctly, when some changes are made to ribbon button while RadRibbonBar is collapsed.

Steps to reproduce:
1. Add button to some ribbon group.
2. Collapse the ribbon.
3. Disable this button.
4. Enable this button.
5. Expand the ribbon.

Workaround - subscribe to ExpandedStateChanged  event and reapply the theme. For example:

            this.radRibbonBar1.ExpandedStateChanged += new EventHandler(radRibbonBar1_ExpandedStateChanged);


        void radRibbonBar1_ExpandedStateChanged(object sender, EventArgs e)
        {
            this.radRibbonBar1.ElementTree.ApplyThemeToElementTree();
        }

Setting the Visibility property of QuickAccessToolBar to collapsed results in collapsed RadRibbonBar TitleBar.

BackstageView changes its location when it is opened on a RadRibbonForm and the form gets maximized.

Enable duplication of RadRibbonBar group's element.

To reproduce: Add a ribbon bar with tabs and items inside. Press alt key and select some tab, in some tabs the children items KeyTIps will not appear.

To reproduce:
Create a RadRibbonForm
Add tab, groups and buttons
Add an ImageList and changed the buttons ImageKey
Minimized the ribbon
Click the tab

Workaround:
Use the image property of the button - 
buttonElement.Image = Image.FromFile(@"image.png");

1. Create a new project with RadRibbonBar. 2. Set the ApplicationMenuStyle to BackstageView 3. Change the application theme to Office2010Blue when handling Form.Load event. 4. Run the project.

add additional minimize options:
    - minimize to panel titles
    - minimize to panel buttons

Attempt to assign two RadButtonElements in RadRibbonBar the same Name at design time results with an Exception dialog instead of the standard dialog.

use radRibbonBar1.BackstageControl.Hide(); to observe the issue.

FIX. RadRibbonBar - the Click event of the OptionsButton is fired twice

ADD. RadRibbonBar - add cancelable CommandTabChanging event.
The event is called CommandTabSelecting to be coherent with the older event CommandTabSelected.

Steps to reproduce.

1. Add a form with a RadRibbonBar 
2. Add a RadCheckBox to the ribbon
3. Set the IsThreeState property of the check box to true
4. Run the project and click through the states of the check box. You will see that the checked and indeterminate states are looking the same way.

Steps to reproduce:
1.Open the ThemeViewer and select a random theme (e.g. TelerikMetro)
2.Click the "Show Form" button, related to "ribbonbar & backstage view, status strip". As a result a RadRibbonForm is shown. Notice that it has a form icon and a QuickAccessToolBar.
3.Click on the arrow button in the QuickAccessToolBar and select "Show below the Ribbon".
Note that the BackColor behind the form's icon is not correct.

Workaround: this.radRibbonBar1.RibbonBarElement.CaptionFill.Margin = new Padding(-20, 0, 0, 0);
