Element disappears when you add a style to it?

Question

.NET

I want to add a context menu to an element, it should support it, but for some reason, when adding it, it simply disappears from the view completely

<Style TargetType="telerik:EventContainer">
            <Setter Property="Background" Value="Green"></Setter>
            <Setter Property="telerik:RadContextMenu.ContextMenu">
                <Setter.Value>
                    <telerik:RadContextMenu>
                        
                    </telerik:RadContextMenu>
                </Setter.Value>
            </Setter>
        </Style>

Answer 1

check the tags first so that everything is opened and closed as expected
