WPF: Disappearing Icons

I have several icons that are declared in Window.Resources. They are displayed for the first time when they need to appear (for example: clicking on the Menu, MenuItem icon), but after displaying another menu (for example: context menu), the initial icon disappears and does not return. As if the last item that used the icon for the first time gets it.

<Window.Resources> <Image x:Key="Chart_16" Source="pack://application:,,,/Resources/images/chart_16.png" /> ... <Window.Resources> <MenuItem Header="Summary" Command="loc:AppCommands.ShowSummary" Icon="{StaticResource Chart_16}" />

I tried to save it as 24-bit PNG, interlaced 24-bit PNG and 8-bit PNG, but the same thing happens. This is not only one, each icon that is used in several places behaves this way.

This is because your Image resource, which is Control . Control can have only one parent, so it is effectively updated in every MenuItem on the fly.

Your options:

  • Do not use Image and instead use an ImageSource or even a string containing the URI of the image.
  • Define a resource that does not share the x:Shared XAML attribute. If necessary, several Image controls will be created.
