I have been really struggling to customize the look of my context menu without losing any functionality. What I have currently would be workable, except that for some reason I can't click any item.

I have a breakpoint in my code-behind for the XamlContextMenu.ItemClicked. When I run the program and click an item, I get a null pointer exception - before the breakpoint even gets hit. It takes me to the 'app.Run()' call. 

Here's the menu:

                                    <ig:ContextMenuService.Manager>
                                        <ig:ContextMenuManager OpenMode="LeftClick">
                                            <ig:ContextMenuManager.ContextMenu>
                                                <ig:XamContextMenu>
                                                    <ig:XamContextMenu.Items>
                                                        <ig:XamMenuItem Header="Mountain Map" Icon="{StaticResource IconMountains}" CommandParameter="{x:Static enums:ClientTabScreenType.MountainMap}" Click="XamMenuItem_OnClick" />
                                                        <ig:XamMenuItem Header="All Machines" Icon="{StaticResource IconMachines}" CommandParameter="{x:Static enums:ClientTabScreenType.AllMachines}" />
                                                        <ig:XamMenuItem Header="Alarms" Icon="{StaticResource IconAlarms}" CommandParameter="{x:Static enums:ClientTabScreenType.Alarms}" />
                                                        <ig:XamMenuItem Header="Logging" Icon="{StaticResource IconLogging}" CommandParameter="{x:Static enums:ClientTabScreenType.EventLogs}" />
                                                        <ig:XamMenuItem Header="Chat" Icon="{StaticResource IconChat}" CommandParameter="{x:Static enums:ClientTabScreenType.Chat}" />
                                                        <ig:XamMenuItem Header="Trending" Icon="{StaticResource IconTrending}" CommandParameter="{x:Static enums:ClientTabScreenType.Trending}" />
                                                        <ig:XamMenuItem Header="Reporting" Icon="{StaticResource IconReporting}" CommandParameter="{x:Static enums:ClientTabScreenType.Reporting}" />
                                                        <ig:XamMenuItem Header="Weather Stations" Icon="{StaticResource IconWeather}" CommandParameter="{x:Static enums:ClientTabScreenType.WeatherStations}" />
                                                    </ig:XamContextMenu.Items>
                                                </ig:XamContextMenu>
                                            </ig:ContextMenuManager.ContextMenu>
                                        </ig:ContextMenuManager>
                                    </ig:ContextMenuService.Manager>

and the styles:

        <Style TargetType="ig:XamContextMenu">
            <Setter Property="Foreground" Value="#FFFFFF"/>
            <Setter Property="Background" Value="Transparent" />

                </Setter.Value>
            </Setter>
        </Style>
