I have a property in a component that is a collection (array). The base type
of the item in the array contains a type which has another array. I edit the
the first array (default collection editor invoked from property grid) from
which I can edit the "next level" array. I  have a custom editor
(UITypeEditor) for the second array. My editor needs information from other
properties in the component in order to display appropriate information. How
do I obtain the component being edited?

Example of layout:

class MyComponent: Component
{
   public string AString
   {
       ...
   }

   public MyFirstType[] First
   {
       ...
   }
}

class MyFirstType
{
   public int AnInt
   {
       ...
   }

   [Editor(typeof(MySecondTypeUIEditor), typeof(UITypeEditor))]
   public MySecondType[] Second
   {
       ...
   }
}

class MySecondType
{
   ...
}

In the EditValue override for my custom UITypeEditor context.Instance points
to an object of type MyFirstType. I assume that I can use provider but I'm
not sure which service to request.

Thanks,

Rick
