In the dashboard on the http://local.live.com there is a toggle arrow button which allows to hide/show dashboard container. When I'm using http://dev.virtualearth.net/mapcontrol/v3/mapcontrol.js script this button is hidden. I’m able to show it (code: map.vemapcontrol.GetDashboard().ShowToggleGlyph();), but toggling doesn’t work.
What should I do to get the same behavior as on the local live site with this dashboard toggling button
Thanks for help!

How to turn on a behavior of toggle button in dashboard?

We don't expose that behavior in the APIs, but you could wire up your own. I would probably create my own map control, add the toggle icon, and in the onclick you just change the size/shape of the control.
(You notice there are a lot of things built into WLL that aren't in the map control. That's expected: WLL is basically just a big mashup that uses the map control as a foundation. You'll find a lot of other mashups out there that use the map control and have used different dhasboards to do similar things).
