Missing StaticResource error (ScrollBarStyle) is thrown when using implicit styles and merging the Telerik.Windows.Controls.RichTextBoxUI.xaml file.

The tool does not found issues in a Silverlight project

 

Here is the error:

Invalid XmlnsDeclaration occurs in assembly 'Telerik.Windows.Controls.GridView, Version=2018.3.1016.1050, Culture=neutral, PublicKeyToken=5803cfa389c90ce7'. XmlnsDeclaration references a namespace 'Telerik.Windows.Controls.MultiColumnComboBox' that is not in the assembly.

It is reproducible only in Visual Studio 2010 SP1.

At this point not much else is known other than the stack trace. The stack trace suggests that this happens on selection done by dragging the mouse and perhaps the document is with incorrect structure.

Silverlight will be end of life in 2021. But if you look at at the currently supported browsers https://en.wikipedia.org/wiki/Microsoft_Silverlight#Desktop_computers you will see it is only running on Internet Explorer 11. All other browsers have canceled support for Silverlight.

Does it really makes sense to still support Silverlight?

I'm asking because of this: https://docs.telerik.com/devtools/wpf/xamlflix-step-by-step-guide/xamlflix-radbarcode. This is the WPF documentation for radBarcode but it effectivly is talking about Silverlight!

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>

ExtMap Files (for Application Caching) are missing from NuGet Separate Packages although they are included in the full package.  Please include these.

It should be possible when user selects multiple cells on the current view with the CTRL key to return the list of these cells with the ScheduleView method.

When placed in a RadWindow, there is a LayoutCycle exception if the layout transform is re-applied when the content of the LCC is not visible.

Workaround: Set MinHeight to the RadWindow.

When the PngBitmapEncoder uses source from a PNG file with opacity then the result image rendering is gray. The class is available in UI for Silverlight.

The LocalizationManager doesn't apply the ResourceKey if the Content/Text properties are defined in XAML between the opening and closing tag of the control - for example Button or a TextBlock control.

If the Telerik.Windows.Controls assembly is referenced from a local folder whilst the Telerik.Controls.Navigation.dll is referenced from the installation folder, as soon as a control from Navigation is added in a UserControl, a design-time exception is raised.

Create FileThumbnail control:
I would love to have an easy way to display the thumbnail preview of a file. The Windows Shell does it, but the pInvoke code required to make this work is excessive.
Something like this:

Perhaps a "RadFileThumbnail" control?
The Windows API Code Pack for Windows 7 has something like this, but you lock yourself into Windows 7 by using it.

The project configuration wizard displays a list of assemblies that we can include or exclude from the current project.
It would be much more useful if this window lists all the different controls and we select the controls we want to use. Currently, we ne

If the user clicks one of the sides of the cube, it stops spinning and displays the image/control that they clicked on.
Also, if the user clicks the non-rotating image/control, then the cube starts spinning again.

If the user doesn't click on the non-rotating image/control after a specified period of time, that the cube should start rotating again on it's own.
