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.

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."

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.

Fix the animation of the RadWrapPanel.
As a workaround:
<telerik:RadWrapPanel >
				<ei:FluidMoveBehavior AppliesTo="Children" Duration="0:0:0.4">
						<CubicEase EasingMode="EaseOut"/>
						<CubicEase EasingMode="EaseOut"/>
Check the attached project.

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.
