Question

我正在使用安装了SharePoint powertools的Visual Studio 2010中的SharePoint 2010开发沙盒可视化Web部件。 webpart部署并按预期工作，但属性不可编辑。我认为核心问题是WebPartStorageAttribute在沙箱中不可用，但是无法找到有关如何使用可编辑属性创建沙盒webpart的指导。这甚至可能吗？

[ToolboxItem(false)]
[XmlRoot(Namespace="MyNamespace")]
public partial class MyWebPart: System.Web.UI.WebControls.WebParts.WebPart
{
     const string  defaultStartTime = "00:30:00";
     private string _startTime = "00:30:00";

    [Browsable(true)]
    [WebBrowsable(true)]
    [Category("Timer")]
    [Description("Start time to use if the user has not set a different one.")]
    [XmlElement(ElementName="StartTime")]
    [DefaultValue(defaultStartTime)]
    [FriendlyName("Start Time")]       
    public string  StartTime
    {
        get
        {
            return _startTime;
        }
        set
        {
            _startTime = value;
        }
    }
...

上面的代码中是否缺少某些内容？是否可以创建一个可编辑的沙盒webpart，如果可以，它是如何完成的？

我刚刚完成了这个过程，这就是我设法让它在沙箱解决方案和365网站上运行的方式，这是整个示例代码：

注意：我在SharePoint Power Tools for Visual Studio中使用Visual WebPart（SandBoxed）

ToolPartTest.ascx：

<h3>Selected List</h3>
<dd><asp:Literal runat="server" ID="list" /></dd>

TooLPartTest.ascx.cs：

[WebBrowsable(true), Personalizable(true)]
public string ListName { get; set; }

protected override void OnInit(EventArgs e)
{
  base.OnInit(e);
  InitializeControl();
}

protected void Page_Load(object sender, EventArgs e)
{

}

protected override void OnPreRender(EventArgs e)
{
  base.OnPreRender(e);

  list.Text = ListName ?? "(None)";
}

public override EditorPartCollection CreateEditorParts()
{
  return new EditorPartCollection(base.CreateEditorParts(),
    new[]
    {
      new CustomEditorPart
      {
        ID = ID + "_editorPart"
      }
    }
  );
}

ToolPart.cs

public class CustomEditorPart : EditorPart
{
  private DropDownList _list;

  protected override void OnInit(EventArgs e)
  {
    base.OnInit(e);

    _list = new DropDownList();
    _list.AppendDataBoundItems = true;
    _list.Items.Add("");
    _list.DataTextField = "Title";
    _list.DataValueField = "Title";
    _list.DataSource = SPContext.Current.Site.RootWeb.Lists;
    _list.DataBind();

    Controls.Add(new LiteralControl("List: "));
    Controls.Add(_list);

  }

  public override bool ApplyChanges()
  {
    EnsureChildControls();

    if (!string.IsNullOrEmpty(_list.SelectedValue))
      ((ToolPartTest)WebPartToEdit).ListName = _list.SelectedValue;

    return true;
  }

  public override void SyncChanges()
  {
    EnsureChildControls();

    var webpart = ((ToolPartTest)WebPartToEdit);
    _list.SelectedValue = webpart.ListName;

  }
}
