关于PropertyGrid控件的详细用法请参考文献：

首先定义一个要在下拉框显示的控件：

using System;  using System.Windows.Forms;  namespace Simon.WinForms.Examples.PropertyGrid  {      public class EditorControl : UserControl      {          public EditorControl()          {              this.label1 = new System.Windows.Forms.Label();              this.label1.AutoSize = true;              this.label1.Location = new System.Drawing.Point(21, 24);              this.label1.Name = "label1";              this.label1.Size = new System.Drawing.Size(41, 12);              this.label1.TabIndex = 0;              this.label1.Text = "名称：";                this.comboBox1 = new System.Windows.Forms.ComboBox();              this.comboBox1.FormattingEnabled = true;              this.comboBox1.Items.AddRange(new object[] {              "名称一",              "名称二",              "名称三",              "名称四"});              this.comboBox1.Location = new System.Drawing.Point(56, 21);              this.comboBox1.Name = "comboBox1";              this.comboBox1.Size = new System.Drawing.Size(133, 20);              this.comboBox1.TabIndex = 2;              this.comboBox1.SelectedIndexChanged += new System.EventHandler(this.comboBox1_SelectedIndexChanged);                this.SuspendLayout();              this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);              this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;              this.Controls.Add(this.comboBox1);              this.Controls.Add(this.label1);              this.Name = "EditorControl";              this.Size = new System.Drawing.Size(210, 64);              this.ResumeLayout(false);              this.PerformLayout();          }            private Label label1;          private ComboBox comboBox1;            public string result = "";          private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)          {              result = comboBox1.SelectedItem.ToString();          }      }  }

从System.Drawing.Design.UITypeEditor继承一个自定义属性编辑管理器类，参考如下：

using System.Drawing.Design;  using System.Windows.Forms.Design;    namespace Simon.WinForms.Examples.PropertyGrid  {      public class Editor : UITypeEditor      {          public override UITypeEditorEditStyle GetEditStyle(System.ComponentModel.ITypeDescriptorContext context)          {              // 编辑属性值时，在右侧显示...更多按钮              return UITypeEditorEditStyle.Modal;          }            public override object EditValue(System.ComponentModel.ITypeDescriptorContext context, System.IServiceProvider provider, object value)          {              var edSvc = provider.GetService(typeof(IWindowsFormsEditorService)) as IWindowsFormsEditorService;              if (edSvc != null)              {                  var popedControl = new EditorControl();                  // 还有ShowDialog这种方式，可以弹出一个窗体来进行编辑                  edSvc.DropDownControl(popedControl);                  value = popedControl.result;              }              return base.EditValue(context, provider, value);          }      }  }

定义一个使用PropertyGrid显示属性的类型。

using System.ComponentModel;    namespace Simon.WinForms.Examples.PropertyGrid  {      public class ShowedClass      {          [DisplayName("名称")]          [Editor(typeof(Editor), typeof(System.Drawing.Design.UITypeEditor))]          public string Name { get; set; }            [Editor(typeof(Editor), typeof(System.Drawing.Design.UITypeEditor))]          public string Description { get; set; }      }  }

在窗体上放好PropertyGrid，然后把你的类实例化后让PropertyGrid来显示设置就可以看到效果了。

propertyGrid1.SelectedObject = new ShowedClass() { Name="我没名字"};
