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}"

                                Content="{TemplateBinding NoResultsContent}"
                                ContentTemplate="{TemplateBinding NoResultsContentTemplate}"
                                Visibility="Collapsed"

Workaround: Set MinHeight to the RadWindow.

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.
The excpetion is "Error HRESULT E_FAIL has been returned from a call to a COM component."

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:
http://stackoverflow.com/questions/1439719/c-sharp-get-thumbnail-from-file-via-windows-api
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.

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.

"It would be really useful to have a RadComboBox with a RadTreeView.

The combination of RadDropDownButton with a RadTreeView seems to be an insufficient workaround:
- start-up item setup
- sync current item
- IsOpen hack in MVVM
- no validation support - which is a serious drawback
- no edit/search support"

When IsTabStop = False the focus is going through :

 *  RadAutoCompleteBox
 *  RadComboBox (when IsEditable is set to True)
 *  RadNumericUpDown
 *  RadMaskedTextInput
 *  RadDatePicker
 *  RadDateTimePicker

Available in the R3 2016 Release.

For RadAutoCompletebox, RadComboBox, RadDateTimePicker and RadNumericUpDown, the TabNavigationExtensions.IsTabStop attached property should be used to indicate whether the control is included in the tab navigation cycle.

For RadMaskedTextInput, MaskedInputExtensions.IsEditorTabStop attached property should be used.
