How do you close a dockpane or deactivate it using a button on the dockpane

[MichaelStranovsky]

I created a dockpane with a cancel button,   I want to close (not hide) the dockpane when I click cancel.

Is there a specific reason you want to close it with a cancel button? It comes with a closing control already.

Hi Michael,

I use the same Add-ins button to open or close dockpane. To close dockpane just call Hide();
