Hi all!

I have created a Canvas, and within it I placed a StackPanel. The StackPanel is horizontal, and it accepts a list of thumbnailed images. The Canvas has a fixed size. When I put more thumbnails than the Canvas width can hold, the StackPanel is supposed to overflow from the Canvas, so I can move it to center the current thumbnail.

Everything works correctly, only, the StackPanel's overflow is visible! Is there a way to hide it? Or is the entire approach wrong?

Here is a screenshot. The canvas is the red box. The stackpanel is blue semi-transparent.

Since the Canvas has fixed size, you can use clipping. Basically you have to do:

<Canvas Width="400" Height="300">
    <Canvas.Clip>
         <RectangleGeometry Rect="0, 0, 400, 300"/>
    </Canvas.Clip>
    <!-- your StackPanel here -->
</Canvas>
