熟悉VS SDK开发的请帮我解决一个问题

当前我新建了一个基于Component类，并声明为IRootDesigner

现在出现的效果就是在VS设计模式时，可以出现一个带点的面板（那些点都是自己用双缓冲+GDI画的）

如下图所示：




现在出现的情况就是我想在设计面板中点击鼠标右键，弹出菜单后出现“查看代码”“粘贴”“属性”等操作，类似于WinForm设计时右键菜单。请问该如何实现。

注：现在我已安装好VS SDK 2008 SP1

以下附基于Component类的代码：

1. DesignPanel

using System;

using System.Collections.Generic;

using System.Text;

using System.ComponentModel;

using System.ComponentModel.Design;

using System.Windows.Forms;



namespace eWhereThink.Workflow.Design

{

    [Designer(typeof(DesignPanelDesigner), typeof(IRootDesigner))]

    [Designer(typeof(ComponentDesigner))]

    [ToolboxItem(false)]

    public class DesignPanel : Component

    {

        public DesignPanel()

        {



        }



    }

}

2. DesignPanelDesigner

using System;

using System.Collections.Generic;

using System.Text;

using System.ComponentModel.Design;

using System.Drawing.Design;

using System.ComponentModel;

using System.Windows.Forms;

using System.Windows.Forms.Design;



namespace eWhereThink.Workflow.Design

{

    public class DesignPanelDesigner : ComponentDocumentDesigner, IRootDesigner

    {

        DesignControl _rootViewControl;



        public DesignPanelDesigner()

        {

            

        }



        public object GetView(ViewTechnology technology)

        {

            _rootViewControl = new DesignControl(this);

            return _rootViewControl;

        }



        public ViewTechnology[] SupportedTechnologies

        {

            get

            {

                return new ViewTechnology[] { ViewTechnology.Default };

            }

        }



        protected override bool GetToolSupported(ToolboxItem tool)

        {

            MessageBox.Show(tool.TypeName);

            return true;

        }



        public void ToolPicked(ToolboxItem tool)

        {

            MessageBox.Show(tool.TypeName + "     ToolPicked");

        }

    }

}

3. DesignControl

using System;

using System.Collections.Generic;

using System.Text;

using System.Windows.Forms;

using System.Collections;

using System.Drawing;

using System.Drawing.Drawing2D;

using System.ComponentModel;



namespace eWhereThink.Workflow.Design

{

    [ToolboxItem(false)]

    public class DesignControl : ScrollableControl

    {

        private DesignPanelDesigner _rootDesigner;

        private IContainer components;

        private Hashtable _componentInfoTable;



        public DesignControl(DesignPanelDesigner rootDesigner)

        {

            InitializeComponent();

            _rootDesigner = rootDesigner;

            _componentInfoTable = new Hashtable();



            SetStyle(ControlStyles.AllPaintingInWmPaint, true);

            SetStyle(ControlStyles.UserPaint, true);

            SetStyle(ControlStyles.OptimizedDoubleBuffer, true);

            SetStyle(ControlStyles.ResizeRedraw, true);



            this.Invalidate();

        }



        private void InitializeComponent()

        {

            this.SuspendLayout();

            // 

            // DesignControl

            // 

            this.Paint += new System.Windows.Forms.PaintEventHandler(this.DesignControl_Paint);

            this.ResumeLayout(false);



        }



        private void DesignControl_Paint(object sender, PaintEventArgs e)

        {

            float fZoom = 1F;



            Size size = new Size();

            size.Width = Math.Max(this.Width, this.AutoScrollMinSize.Width);

            size.Height = Math.Max(this.Height, this.AutoScrollMinSize.Height);



            Bitmap bmp = new Bitmap(size.Width, size.Height);

            Graphics g = Graphics.FromImage(bmp);

            Color selectColor = Color.FromArgb(102, 102, 255);

            Brush selectBrush = new SolidBrush(selectColor);

            try

            {

                g.SmoothingMode = SmoothingMode.HighQuality; //高质量

                g.PixelOffsetMode = PixelOffsetMode.HighQuality; //高像素偏移质量



                //画点

                for (int iX = (int)(10 * fZoom); iX < bmp.Width; iX += (int)(10 * fZoom))

                {

                    for (int iY = (int)(10 * fZoom); iY < bmp.Height; iY += (int)(10 * fZoom))

                    {

                        bmp.SetPixel(iX, iY, Color.Black);

                    }

                }

                e.Graphics.DrawImage(bmp, 0 - this.HorizontalScroll.Value, 0 - this.VerticalScroll.Value);

            }

            catch (Exception err)

            {

                MessageBox.Show(err.Message);

            }

            finally

            {

                selectBrush.Dispose();

                g.Dispose();

                bmp.Dispose();

            }



        }

    }

}

如果新建一个类是继承于DesignPanel的，就可以看到设计时面板的状况了


谢谢！
