Hi, this is my first question, I've been looking for a solution for 2 days and nothing.


Im creating a custom control that uses a picturebox and im trying to select the image from the property grid... but I get this error:

Error 2 The type or namespace name 'ImageEditor' does not exist in the namespace 'System.Drawing.Design' (are you missing an assembly reference?) C:\Users\Personal\...\ImageButton.cs 33 51 My Project

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Imaging;
using System.Drawing.Design;

namespace MyNamespace
{

  public partial class ImageButton : UserControl
  {
    public ImageButton()
    {
      InitializeComponent();
    }

    private Image normal;

    public string TestString // Just for test if the property is displayed in the property box -and it does -
    {
      set;
      get;
    }

    // Im getting the error in the next line.. 
[EditorAttribute(typeof(System.Drawing.Design.ImageEditor),typeof(System.Drawing.Design.UITypeEditor))] // According to http://msdn.microsoft.com/en-us/library/system.drawing.design.imageeditor.aspx
    public Image ImageNormal
    {
      set  
      {
        normal = value;
      }
      get
      {
         return normal;
      }

    }
}
}

I've tried using differents versions of .net framework 2.0, 3.5, 4 and the same problem, also i've tried to use VS2010 Express Edition and Professional on different PCs and im getting the same problem...

I can assign the Image property programmatically, but when I show the form on the designer, I get another error, saying that the custom control class does not have a property called ImageNormal... but it does..

when I browse the namespace System.Drawing.Design I cannot see all the classes that it should have (according to http://msdn.microsoft.com/en-us/library/ks225801[^]), only

CategoryNameCollection
PaintValueEventArgs
PropertyValueUIItem
ToolboxComponentsCreatedEventArgs
ToolboxComponentsCreatingEventArgs
ToolboxItem
ToolboxItemCollection
UITypeEditor

all the Prebuilt UITypeEditors classes are missing! (BitmapEditor, ColorEditor, ContentAlignmentEditor, CursorEditor, FontEditor, FontNameEditor, IconEditor, ImageEditor, MetafileEditor)

so I wonder why is this happenig to me, I supose im doing something wrong... the APP is a Windows Forms Application.

Any help will be appreciated.

PS: Excuse me if there is anything wrong/weird with my English.
