  • 0

I have a StackPanel and for some reason I can’t get the content of the ScrollViewer on the very bottom to be scrollable, despite the fact that the internal height of the Frame clearly exceeds the bounds of the ScrollViewer. I previously had a Grid as the root container of the Window, but when I changed it to StackPanel the scrollbar no longer appears.

The only thing that seems to work is if I explicitly set the height of the ScrollViewer, but then it does not size with thw Window when it’s resized.

Do I have to use a Grid?

Sorry if this is obvious; I’m relatively new to WPF.

Thanks in advance for any help!

    The ScrollViewer in the bottom does not have a fixed height, and therefore because it’s contained in a StackPanel, its height will be the height of the content, which in this case is the Frame height.

    You can either set a fixed height for the ScrollViewer, or use a Grid instead of a StackPanel. In case you use a grid you should set a fixed height for the row in which the ScrollViewer will be located.

    Hope it helps!
