The HeaderVisibility property of RadRibbonTab doesn't work when changed at runtime.

A workaround is to use Visibility property of RadRibbonTab, instead of HeaderVisibility

In some cases an InvalidOperationException is thrown when the control is loaded too early (before it is added to the visual tree). This reproduces only when the ribbon's content is minimized initially.

To work this around, you can set the IsMinimizable property of RadRibbonView to False.

In the application menu, we have placed a RadRibbonSplitButton. When the application menu is open, and we press Tab and Space key, the application menu is closed and the UI unresponsive until the mouse leaves the control.

Output error in VS:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.RadRibbonView', AncestorLevel='1''. BindingExpression:Path=IsHostedInRibbonWindow; DataItem=null; target element is 'WindowTitle' (Name='WindowTitle'); target property is 'NoTarget' (type 'Object')

 

The ribbon tab doesn't get selec if you click in the exact middle of the header of RadRibbonTab.

To work this around, extract the ControlTemplate of RadRibbonTab and move the Grid with x:Name="ContentPanel" before the Grid with x:Name="HeaderPanel".

When the RibbonBackstage is open and then a RibbonBackstageItem is clicked to close the backstage, the ApplicationButton's FluentControl pressed state effect remains visible in the Fluent theme.

We have a RadRibbonWindow.
When it is run on Windows XP (or on Windows 7, "Windows Classic" theme) and the DPI settings are high (above 170 %), the standard window buttons (Minimize, Restore and Close) are not displayed properly (they are cut). Also there is too much space between them.

When opening Backstage using KeyTips service, NullReferenceException is thrown when the backstage items have also had KeyTips set. 

When the ContentHeight is set in Xaml or before the control is loaded it is not respected. 

Every KeyTipControl is placed inside a Popup. Expose properties which could control the Popup position.

Please support the new Office Simplified Ribbon: https://support.office.com/en-us/article/use-the-simplified-ribbon-44bef9c3-295d-4092-b7f0-f471fa629a98?ui=en-US&rs=en-US&ad=US.

Currently, you can navigate through the elements of the ribbon only via the keytips or the arrow keys. Add support for the Tab key as well.

In other words when you enter the keyboard navigation mode, the Tab key should work along with the arrow keys. See Word's ribbon for a reference.

 

In the Crystal theme, the TitleBarBackground property is set through a style trigger to a static value. This leads to an unexpected result in the dark variation of the theme. 

As a workaround you can use the following style:

  <Style TargetType="telerik:RadRibbonView" BasedOn="{StaticResource RadRibbonViewStyle}">
            <Style.Triggers>
                <Trigger Property="IsHostedInRibbonWindow" Value="True">
                    <Setter Property="TitleBarBackground" Value="{telerik:CrystalResource ResourceKey=AlternativeBrush}"/>
                </Trigger>
            </Style.Triggers>
   </Style>

 

 

Scheduled for:
The fix for this issue will be available with LIB (version 2019.1.121) scheduled for publishing on Monday, 21st January 2019.

The property allows you to align the minimize, maximize and close buttons to the left or the right of the window's header. Currently, this is implemented to work only for RadWindow. Add support also for the RadRibbonWindow

This is reproducible only in the FluentTheme. Setting the RadCollapsiblePanel.SmallButtonsPerColumn to 3 does not make any difference.  

The workaround is to set a higher value for the ContentHeight property of RadRibbonView, for example 120px.

The fix for this issue will be available with LIB (version 2018.3.1203) published on Monday, 3-rd December, 2018. 
 

Workaround for this bug is setting Style.Triggers for this scenario.

<Style BasedOn="{StaticResource RadRibbonSplitButtonStyle}" TargetType="telerik:RadRibbonSplitButton">
  <Style.Triggers>
    <MultiTrigger>
      <MultiTrigger.Conditions>
        <Condition Property="IsChecked" Value="True"/>
        <Condition Property="IsEnabled" Value="True"/>
        <Condition Property="CurrentSize" Value="Medium"/>
      </MultiTrigger.Conditions>
      <MultiTrigger.Setters>
        <Setter Property="Foreground" Value="{DynamicResource CheckedBrush}"/>
      </MultiTrigger.Setters>
    </MultiTrigger>
  </Style.Triggers>
</Style>
