[RESOLVED] Making a usercontrol property editable at design time?

[MrPolite]

Hi...
i have a property in my user control that is a collection of objects. How can i make it so the users can edit the collection at design time (just like how you can edit the Items property for a listbox in VS.NET and add/remove items)

Imports System.ComponentModel
 
Public Class UserControl1
 
    Private _b As New List(Of Beer)
 
    <DesignerSerializationVisibility(DesignerSerializationVisibility.Content), _
    Description("A list of beers is better than just one."), _
    Browsable(True)> _
    Public Property Beers() As List(Of Beer)
        Get
            Return _b
        End Get
        Set(ByVal value As List(Of Beer))
            _b = value
        End Set
    End Property
 
End Class
 
Public Class Beer
 
    Public Enum Tastiness
        Keystone
        Coors
        Guiness
    End Enum
 
    Private _name As String = Nothing
    Private _tastiness As Tastiness = Nothing
 
    Public Property TastinessLevel() As Tastiness
        Get
            Return _tastiness
        End Get
        Set(ByVal value As Tastiness)
            _tastiness = value
        End Set
    End Property
 
    Public Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            _name = value
        End Set
    End Property
 
End Class

This works for me. I found this doc helpful in this instance: http://msdn.microsoft.com/en-us/libr...attribute.aspx

cool works! thanks!!!

hmm but i guess a question that remains is how to you figure out if the property was updated? (it if an item was added to the List ?)
(I need to update the UI items based on what's in that List collection)

I'm unsure on this. I'll need to research further. In the meantime, this looks like an interesting set of articles: http://amrelsehemy.net/post/2008/01/...ttributes.aspx

hmm thanks again
i can't think of any easy way to do this
do i need to make my own custom List<> class that would raise an event when someone adds/remove items?
