加入一個propertyGrid

PropertyGrid propertyGrid1 = new PropertyGrid();
propertyGrid1.CommandsVisibleIfAvailable = true;
     propertyGrid1.Location = new Point(10, 20);
     propertyGrid1.Size = new System.Drawing.Size(400, 300);
     propertyGrid1.TabIndex = 1;
     propertyGrid1.Text = "Property Grid";

this.Controls.Add(propertyGrid1);

下面是事件觸發

我們對<label>元素做例子

private void editocx_onDocumentmousedown()
{
     mshtml.IHTMLElement ele=editocx.getCurElement();
     if(ele==null)return;
     switch(ele.tagName.ToLower())
     {
          case "label":
          AdapterProperty(new LabelElement(ele));
          break;
          //省略其他
          default:
          break;
     }
}
AdapterProperty把對象賦值給propertyGrid的selectobject屬性

private void AdapterProperty(object eleclass)
{
     propertyGrid1.SelectedObject=eleclass;
}

下面是htmlelement屬性適配類，以label舉例，并且對label的id和name這兩個屬性綁定
