Add DataBinding Supoort for Contextual Groups / Tabs

Available in LIB version: 2015.1.0604

Support easy customization of screen tip duration.

Currently the Backstage support keyboard navigation only if the the RadBackstageItems have their IsSelectable property set to true. The keyboard support should be extended to support BackstageItems that have IsSelectable=false.

Will be available in Q2 2015 Release.

When UserControls are dynamically added in the RibbonView Items collection, they are displayed as RibbonTab Headers. Instead they should create a RibbonTab collection where each control represents the content of a RibbonTab.

UPDATE: An implicit style can not be applied on derived controls as their TargetType is different than the one defined in the implicit style. Basically if you set the style implicitly, the style is applied only on the types that match the TargetType exactly and not on elements derived from the TargetType value. You can find more information on the topic in the remarks section of the Style property definition: http://msdn.microsoft.com/en-us/library/system.windows.style%28VS.95%29.aspx

This is why in order to apply a Telerik predefined style on a UserControl deriving from RadRibbonTab, you  need to add a Style targeting the UserControl type in the Resources of the application. It is best to define that style after merging the Telerik ResourseDictionaries so that you can base the UserControl Style on the predefined "RadRibbonTabStyle".

typically users consider keys like Shift,Ctrl,ALT to be a single key even though they are on the keyboard left and right.

Add the ability, while holding down a modifier key (for instance ALT which triggers the KeyServices) and pressing the AccessText key at the same time, to execute the action associated with the element.

Available in R1 2017 Release
Please note that is it working only for KeyDown ActivationModes, not in the default KeyUp.

NullReferenceException design-time exception is thrown in VS designer when the RadRibbonTab is defined as a root element of a UserControl.

When you set the Content and the Image properties of the RadGalleryItem, they get on top of each other.

There is a flickering when the active ContextualGroup is changed - the RibbonView first selects the non-contextual main tab before it switches to the according contextual tab. The flickering can't be observed every time.

There are three errors for missing icons when implicit themes are used:
Resource '/Telerik.Windows.Controls.RibbonView;component/HelpIcon.png' was not found.
Resource '/Telerik.Windows.Controls.RibbonView;component/RibbonGalleryCollapsedIcon.png' was not f

At the moment the root element of the Backstage control is a ScrollViewer and since its size is measured with infinity the controls placed inside the BackstageItems Content will be measured with infinity thus not displaying internal scroll bars. Consider changing this behavior.


The feature will be available in our official release 2015 Q1

If a RibbonView is used in a WPF, where the Window SizeToContent property is set to WidthAndHeight, the Window takes too much space.

Setting Button, TextBlock, TextBox or any other UI Element as a Header of RadRibbonGroup produces a runtime exception: The Element is Already Child of another visual.

Expose a property to control the visibility of the background behind the RibbonTab.Headers

UPDATE: The RadRibbonView's Background property can be used to set a color behind the RadRibbonTabs

VS Designer trows exceptions if a RibbonTab is placed in a UserControl:  

If the RibbonTab control size isn't defined, the designer throws a System.InvalidOperationException - FrameworkElement_LayoutMeasure_InfinityNaNReturned.  

If the RibbonTab size is set, then clicking on the tab in the designer raises a System.ArgumentException - Property 'Items' was not found in the property collection 'Grid'. 

When the Ribbon is hosted in a RibbonWindow, the ContextualGroups are rended differently Q3 2013 release.

The ScreenTip isn't displayed unless you define its Title property

If you place a TextBlock in the QuickAccessToolbar and the Ofice_Black theme is applied you get black foreground on black background which makes the text unreadable. The content of the QAT must respect the theme applied to the RadRibbonView control.

Open the Application menu.
Open one of its submenus.
Hover another button.

The opened submenu will not close.
