 public class MyClass
{
     [

You sort of can. I'm trying something like this at the moment, which I managed to get working with CategoryAttribute. Currently though, this stops the propertiesgrid from working all together though, even though this is being called in the constructor of a button:

Dim PC As PropertyDescriptorCollection = TypeDescriptor.GetProperties(Me)
For i As Integer = 0 To PC.Count - 1
        Dim att As BrowsableAttribute = DirectCast(PC(i).Attributes(GetType(BrowsableAttribute)), BrowsableAttribute)
        If Not att Is Nothing Then
            If att.Browsable = True Then
                Dim cat As Reflection.FieldInfo = att.GetType.GetField("Browsable", Reflection.BindingFlags.NonPublic Or Reflection.BindingFlags.Instance Or Reflection.BindingFlags.Public Or Reflection.BindingFlags.Static Or Reflection.BindingFlags.IgnoreCase)
                If Not cat Is Nothing Then
                    cat.SetValue(att, False)
                End If
            End If
        End If
Next

Hope this helps
