Floating Dockpane Width and Height as a proportion of screen resolution

[NaveenAdair]

Is there a way to set the initial width and height of a floating Dockpane as a proportion of the screen resolution?

I understand that the width or height is set in DAML via the width and height attributes.  ie:

<dockPane id="myDockpane"

     caption="My Dockpane"

     className="myDockpaneViewModel"

     dock="float"

     width="1200"

     height="700"

   <content className="myDockpaneView" />

</dockPane>

However, how can i make these values proportional to the screen resolution of the current user?  For example, if the users screen resolution was 1920 x 1080 and i wanted the initial floating dockpane to be 60% of this (i.e. 1152 x 648).

Can this be achieved via Bindings or Code-Behind?  I am unsure as to how this would work in DAML (where the Dockpane width and height are set) as opposed to conventional approaches in XAML.

Any assistance is kindly appreciated.
