How to group properties of a class together???

Hi guyz. Thanx for sparing some time looking at my problem.

I'm creating a new custom control by inheriting System.Web.UI.WebControls.GridView

Namespace WebControls
Public Class XGridView
    Inherits System.Web.UI.WebControls.GridView
        Public Property SortAscImageUrl() As String
            Get
                'Some codes here
            End Get

            Set(ByVal value As String)
                'Some codes here
            End Set
        End Property
End Class
End Namespace

I want to place the above property under the group PagerSettings.
(In the Visual Designer IDE where you can drag and drop controls, drag a GridView onto the WebForm. Then view its properties in the Property dockable window. Scroll down to PagerSettings. Notice that PagerSettings can be expanded to display other properties grouped under it. I want to place my property SortAscImageUrl there.)
However, if I code as above, my property won't appear under any 'group property' or whatever you call it. It'll appear at the top most hierarchy together with other properties.

Can somebody show me too how to create a new 'group property' so that I can place all my new custom properties under it and can be accessible from the visual designer.

I have tried something like

<Category("Sorting")> _
    Public Property SortAscImageUrl() As String

but it doesn't work the way I wanted. This method will only assigned the property a category which is only useful when we sort the properties in the property dockable window by category instead of alphabetically. The property will still be 'groupless'.

Thanx in advance.

You need to use an ExpandableObjectConverter.

Here is an example of what I mean:
