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.
I assume that even though this is listed under RadControls for Silverlight it will also apply to RadControls for WPF.
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".
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
We have a RadRibbonView with enabled KeyTips and a RadComboBox control below it. We focus the RadComboBox and press "Alt + DownArrow". As a result the the RadComboBox is opened and immediately closed and KeyTip is activated and shown and the coressponding RadRibbonTab gets the focus. The expected result is that the RadComboBox is opened, remains opened and no KeyTips are activated.
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.
This issue occurs when the ApplicationMenu is bound. The button in the ItemTemplate of the ApplicationMenu could be both RadSplitButton and RadDropDownButton. Their DropDownContent should not be displayed downwards, it should be displayed in the RightPane ( the Content of the Applicationmenu) Declined: When the ApplicationMenu is in DataBound scenario the ItemsControl from which the ApplicationMenu inherits automatically creates ContentPresenters for each item and wraps their content. As the ApplicationMenu knows how to manage RadRibbonDropDown/Split buttons you will need to provide one of these containers as direct child of the menu. You can achieve that using the following code, to show all items as RadRibbonDropDownButton: public class CustomApplicationMenu : ApplicationMenu { protected override bool IsItemItsOwnContainerOverride(object item) { return false; } protected override DependencyObject GetContainerForItemOverride() { return new RadRibbonDropDownButton(); } }
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
When both Command and IsEnabled of RadRibbonBackstage are bound, the Command has Higher priority. This is inconsistency with the behavior of Buttons and RadButtons. The RadRibbonBackStageItems should work like RadButtons.
ElementName binding is not working in RadRibbonBackstage. Reason for closing: The ElementName binding in Adorner is not supported and as the RadRibbonBackstage is Adorner it is not working there as well. Due to that framework limitation we cannot fix this issue and we will change the status of the feed back item to declined. You can find more information about the Adorner and its limitation in this article ( http://msdn.microsoft.com/en-us/library/ms743737%28v=vs.110%29.aspx ).
When the Ribbon is hosted in a RibbonWindow, the ContextualGroups are rended differently Q3 2013 release.
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'.
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.
The ScreenTip isn't displayed unless you define its Title property
Open the Application menu. Open one of its submenus. Hover another button. The opened submenu will not close. Available in LIB version: 2016.3.1017
