1. I have a MDI document what is the best way to link data form a
specific MDI document to parameters of a property grid. In this case I
have a palette that can change from document to document, and I want my
customized color picker to support the diffrent palettes depending on
what document is active.

2. I have a large set of bjects that use a single class in the Property
grid, However the classes that derive this need to ensure that certain
parameters remain set when ConvertFrom is called because they are
static values.

Chris,

For #1, the easiest way to do this would be to create a class that
exposes the properties that you want which you can bind to the property
grid.

For #2, in your derived classes, just throw an exception when the
property is set with an invalid value. It will prevent the value from being
entered.

Hope this helps.

This isn't exactly what I want, so let me try to explain what I am
trying to do.

I have a property that can bind to a set of data that the user can set
elsewhere in the document or here. So I want it to drop a list, using
the string converter if possible that looks something like this

+ SomeObject | Data
(Disabled)
OtherObjectA
OtherObjectB
OtherObjectC
(New Object)

When "(New Object)" is clicked I want it to create a window that
allows the users to create a new object and click Ok, naturally a
Cancel will be present too. This list of objects is unique for each
document. Additionally, the SomeObject has a filtering parameter that
tells it what objects can be used and what objects can not be used. It
sounds kind of counter intuitive from a Human Factoring stand point but
it actually will work in a very eloquent way. I am beginning to believe
that the only way to do this is with the "..." button but I wanted to
avoid that because about 90% of the time the user would select one of
the objects that already exists.
