UserControls/Design Time Property Grid

You can do so by providing a category attribute to your property. For instance:

[Category("Layout")]
public Point Location
{
get { return m_Location; }
}

If you plan to use separate classes to bundle properties, use the ExpandableObjectConverter attribute on the class in order to be able to open a sub-item in the propertygrid.

Hope this helps

Sure...
you can supply a TypeConverter attribute to a property. The TypeConverter will convert your datatype to a string a vice versa. This is the string that is displayed next to your property. A typeconverter can also tell the propertygrid what properties are available for editing. That's where the ExpandableObjectConverter comes into play: it is derived from TypeConverter and implements default behaviour for exposing sub-properties.

Does that make any sense?

Let's assume you set the SelectedObject of your propertygrid to some instance of object Foo, which has a property of type Bar. In this example the propertygrid will display a property Bar, in the category "SomeCategory", and you can open it up because the class has the ExpandableObjectConverter applied to it.

[TypeConverterAttribute( typeof( ExpandableObjectConverter ) )] public class Bar { public string Name { get { return m_Name; } set { m_Name = value; } } public int SomeValue { get { return m_SomeValue; } set { m_SomeValue; } } public class Foo { [Category("SomeCategory")] public Bar Bar { get { return m_Bar; } set { m_Bar = value; } } }

I would further suggest browsing for ExpandableObjectConverter and TypeConverter in the docs and on google, there are lots of articles on the subject.

Does this answer your question?
