Aligning Content In A WPF Viewbox
Answer : Try VerticalAlignment="Top" and HorizontalAlignment="Left" on your viewbox. It will cause it to be anchored to the top and left side. <Grid> <Viewbox VerticalAlignment="Top" HorizontalAlignment="Left"> ... </Viewbox> </Grid> If you want it to completely fill (but keep it uniform) you can use Stretch="UniformToFill"
