Default built-in editors for the PropertyGrid control

I can't seem to find the answer to this anywhere. What default editors/converters are building into 3.5 Framework PropertyGrid control. Otherwise what object types can I throw at it and it be able to reliably show and edit? I've found a lot of tutorials on using custom editors (which I may do at some point). But right now in my program I'm allowing the user to create their own custom properties and I want to know what object types I should allow assuming they will be editing them in a PropertyGrid.

You might want to take a look at classes that derive from UITypeEditor (in the System.Drawing.Design namespace). These types will be passed as parameters to the EditorAttribute (in the System.ComponentModel namespace).

You can also look at the metadata for the type to see where the EditorAttribute is applied. However, do not use reflection here, as that is not what the PropertyGrid class uses.

Rather use the TypeDescriptor class to get property descriptors for the properties on the type (call the static GetProperties method). Then, with the PropertyDescriptor instance, call the GetEditor method to get an instance of the editor for that property.

Besides UITypeEditors, the PropertyGrid is able to display any object with a TypeConverter that returns true for CanConvertFrom(String). You can implement your own TypeConverters for specific object types in order to accomplish this.

The PropertyGrid uses TypeConverters and there are TypeConverters for every primitive type (as well as collections of primitive types).

As long as you're using one of the primitive types or a collection of primitive types the property grid should be able to take care of providing an editing UI.

You can actually throw any object at the PropertyGrid. It will do a lot of things automatically. You only need to create custom UI type editors if you want to have a special edit experience, which is not natively provided. And even in that case you do it per property and not for a whole object.
