How to use ContextMenu?

[alvahtin]

I put ContextMenu in Canvas:

<Canvas>
     ........................
     <Canvas.ContextMenu>
        <ContextMenu>
          <MenuItem Header="test" />
        </ContextMenu>
      </Canvas.ContextMenu>
</Canvas>

But it open when clicked on the controls in Canvas (TextBlock, Lines, etc). But if I click in the free area in Canvas, it don't open.

I try put it in the Window, but it still open when clicked on the controls, but not on free area.

I want the context menu to open everywhere in the Canvas.

You have to set Background="Transparent" or any other color on the Canvas. It is null by default, which means that it's not hit test visible.
