This reproduces only if the FlipDuration property of RadBook is set to 0. 

To work this around set the FlipDuration to a bigger value. For example: FlipDuration="0:0:0.001"

Users want to be able to resize columns of RadPivotGrid at runtime, similar to RadGridView.

The regular ComboBox goes through all of the starting with the same letter items when pressing the same key multiple times. RadComboBox currently always highlights the first one.
In addition, the case where starting to type couple letters, will select the matched item with StartsWith

Allow users to expand properties of a complex type in order to reveal the list of that type's properties.

The feature will be available in R1 2019, scheduled for the mid of January 2019. 

The colors are different everytime the file is opened in the viewer.

The DropDownMenu is incorrectly positioned when the default TabStripPlacement is changed - if the TabStripPlacement is set to Bottom/Left/Right, the DropDownMenuis displayed at the top left corner of the screen.

The current workaround is to edit the control template of the control and set the MinWidth of the PART_ListBox element:

                   <Popup x:Name="PART_Popup">
						<Grid x:Name="PopupRoot">
							<telerik:RadListBox x:Name="PART_ListBox"
												 MinWidth="{TemplateBinding MinDropDownWidth}"
												MaxHeight="{TemplateBinding MaxDropDownHeight}"
                            ItemsSource="{TemplateBinding FilteredItems}"
                            ItemTemplate="{TemplateBinding DropDownItemTemplate}"
                            FontFamily="{TemplateBinding FontFamily}"
                            FontSize="{TemplateBinding FontSize}"/>
							<Border
                            Background="{Binding Background, ElementName=PART_ListBox}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="1"
                            Width="{Binding ElementName=PART_ListBox, Path=Width}"
                            Visibility="{Binding ElementName=PART_NoResultsContentPresenter, Path=Visibility}">
								<ContentPresenter x:Name="PART_NoResultsContentPresenter"
                                MinWidth="{TemplateBinding MinDropDownWidth}"
                                MaxHeight="{TemplateBinding MaxDropDownHeight}"
                                Content="{TemplateBinding NoResultsContent}"
                                ContentTemplate="{TemplateBinding NoResultsContentTemplate}"
                                Visibility="Collapsed"
                                Margin="5 4"/>
							</Border>
						</Grid>
                   </Popup>

Command (Apple key ) + V, C, X, (ArrowKeys) combinations do not work in MaskedInput for Silverlight under MAC.  They should work just like when Control is pressed instead of Command.

For example string '1.23' is pasted in RadMaskedNumericInput and Text becomes 1.23.456 which cannot be parsed to value, and also, Value is not updated at all after Command + V paste operation.

Expected: Text and Value should become 1.23 in scenarios when mask is not empty.

The DataContext is not distribute to Large and Small contents in some cases.

Possible workarouns:
1) Declare the DataContext of TileView in xaml, for example:
   <Window.DataContext>
        <local:MainViewModel />
    </Window.DataContext>

2) Assing DataContext Binding to the three contents:
  <telerik:RadFluidContentControl.LargeContent>
                <Grid DataContext="

 <telerik:RadFluidContentControl.Content>
                <TextBox FontSize="16" DataContext="{Binding}"

            <telerik:RadFluidContentControl.SmallContent>
				<TextBlock FontSize="12" DataContext="{Binding}"

Port the current SL implementation of MediaPlayer to WPF.

Changed the status to Completed: We created a MediaPlayer SDK example which can be used in WPF.
