Setting up sorting order at runtime

Hi

I manage to set the sorting order of my shape all fine when I play with the demo parameters

Then I would like to set that SortingOrder parameter at runtime

and Draw.sortingOrder doesn't exist.

What should I do ?

cheers

ps:

Also, am I using the documentation wrong ?

I find myself digging in the sample and library code all the time to try and

find things 

ex:

it took me a while to come up with things like

Draw.StencilComp = CompareFunction.Less;

Draw.StencilOpPass = StencilOp.Keep;

Draw.StencilRefID = 0;

Draw.StencilReadMask = 255;Draw.StencilWriteMask = 255;
