Add an image in a WPF button

Question

I tried this solution:

<Button>
    <StackPanel>
        <Image Source="Pictures/img.jpg" />
        <TextBlock>Blablabla</TextBlock>
    </StackPanel>
</Button>

But I can see the image only in the project window, and when I launch the program it disappears.

If I try this:

  Image img = new Image();
  img.Source = new BitmapImage(new Uri("foo.png"));

  StackPanel stackPnl = new StackPanel();
  stackPnl.Orientation = Orientation.Horizontal;
  stackPnl.Margin = new Thickness(10);
  stackPnl.Children.Add(img);

  Button btn = new Button();
  btn.Content = stackPnl;

I get a "'System.Windows.Markup.XamlParseException' in PresentationFramework.dll" exception.

What is the solution?

Answer 1

In the case of a 'missing' image there are several things to consider:

1. When XAML can't locate a resource it might ignore it (when it won't throw a XamlParseException)

2. The resource must be properly added and defined:

   • Make sure it exists in your project where expected.

   • Make sure it is built with your project as a resource.

     (Right click → Properties → BuildAction='Resource')

Another thing to try in similar cases, which is also useful for reusing of the image (or any other resource):

Define your image as a resource in your XAML:

<UserControl.Resources>
     <Image x:Key="MyImage" Source.../>
</UserControl.Resources>

And later use it in your desired control(s):

<Button Content="{StaticResource MyImage}" />
