Hi,
Can the native PropertyGrid accept dynamic properties? ones that are not
pre-compiled into a class and don't have those [TAGS] thingies attached to
properties? Can I just instantiate a property grid and put a dynamic "Name"
property in there without having a class with a name property "fed" to it?
Thanks
Ron

...oh. and I can't use a 3rd part tool. I must work off of the native
property grid.

Yes. The API is complex, but you can create 'virtual' properties; set
arbitrary display text; enable and disble; hide and show.

How? any hints? is it by "simulating " properties using the
ICustomTypeDesc riptor interface? or is there another way?

It's been a couple years, so my hint is www.google.com. As I recall,
there was a "property bag" project that didn't have any code we could
actually use, but which pointed in the right direction.
If you're really clueless, I could look at my old code and post some
more tips, but I can't post the old code because I don't own it.

Hi Ron,
Yes, ICustomTypeDesc riptor or you can create a TypeConverter for your class.
Each can be used to create a PropertyDescrip torCollection which contains all
of the properties to be used by the PropertyGrid.
You can create PropertyDescrip tors that don't have any true property backing
by deriving a class from TypeConverter.S implePropertyDe scriptor (nested,
protected abstract class. You can derive a class that is nested in another
custom class that must derive from TypeConverter). If you don't need a custom
TypeConverter or if you just want a "cleaner" method of creating custom
property descriptors, just derive a class from PropertyDescrip tor.

Hi Ron,
pre-compiled into a class and don't have those [TAGS] thingies
Those "[TAGS] thingies" you are referring to are called Attributes. You can
create custom Attributes as well by deriving from the Attribute class to
associate custom meta-data to your classes, structures, enums, their various
members, method arguments, return values, etc.
Attributes are extremely important in managed code, so I suggested that you
research them ASAP and make sure that you understand them.
Even if you don't create your own they are used frequently in the FCL for
various reasons such as CAS, support for the compiler, COM-interop, debugging,
data-binding, serialization, custom meta-data, to supply information about
properties to the PropertyGrid, etc.

PropertyGrid will display any properties you hand to it.
Changes to the .NET 2.0 system have greatly increased the usefulness of the
TypeDescriptor. You should check out the TypeDescription Provider system.
Essentially you can expose properties, filter them, change them even add
totally artificial ones and the PropertyGrid will enable you to edit them.

Hi,
I have a class which I am feeding to the propertygrid, and I am
exposing a Mesh object from my class for the propertygrid to display. I
want the propertygrid to show the values (when you expand the property)
and allow those values to be edited. My code is below. The grid is
showing the values but they are read-only, although the other
properties for the rest of my class are editable.

Hi,
Using the propertygrid, is it possible to have a user selectable 'unit
of measure' for a field.
For example, I am looking at using a propertygrid for defining inputs
into a calculation. Some of the inputs can be either monetary or
percantage. The ideal scenario is where the user enters the value and
immediately to the right of the value field is a drop down, defaulted
to %,which allows a currency to be selected.
