SharePoint 2010：更新View Xml启用工具栏

如何解决SharePoint 2010：更新View Xml启用工具栏

|| 我试图在列表视图上启用“视图”工具栏。但这似乎不起作用。我怎样才能得到正确的代码？

/// <summary>
/// Handles the Click event of the btnEnable control.
/// </summary>
/// <param name=\"sender\">The source of the event.</param>
/// <param name=\"e\">The <see cref=\"System.EventArgs\"/> instance containing the event data.</param>
private void btnEnable_Click(object sender,EventArgs e)
{
    using (SPWeb spWeb = new SPSite(tbSiteUrl.Text).OpenWeb())
    {
        SPList spList = spWeb.Lists[lbLists.SelectedItem.ToString()];
        foreach (SPView spView in spList.Views)
        {
            EnableToolbar(spView.Title,spList.Title,spWeb.Url);
        }
    }
}

/// <summary>

private void EnableToolbar(string viewName,string listName,string webUrl)
{
    SPSecurity.RunWithElevatedPrivileges(() =>
                                             {
                                                 using (var spSite = new SPSite(webUrl))
                                                 {
                                                     using (SPWeb web = spSite.OpenWeb())
                                                     {
                                                         spSite.AllowUnsafeUpdates = true;

                                                         SPList spList = web.Lists[listName];
                                                         SPView spView = spList.Views[viewName];

                                                         XDocument xDocument =
                                                             XDocument.Parse(spView.GetViewXml());

                                                         XElement xElement =
                                                             xDocument.Element(\"View\").Element(\"Toolbar\");
                                                         xElement.RemoveAttributes();
                                                         xElement.SetAttributeValue(\"Type\",\"Standard\");
                                                         xElement.SetAttributeValue(\"ShowAlways\",\"TRUE\");

                                                         spView.SetViewXml(xDocument.ToString());
                                                         spView.Update();

                                                         spSite.AllowUnsafeUpdates = false;
                                                     }
                                                 }
                                             });
}

更新：

using (var spSite = new SPSite(webUrl))
{
    using (SPWeb web = spSite.OpenWeb())
    {
        spSite.AllowUnsafeUpdates = true;

        SPList spList = web.Lists[listName];
        SPView spView = spList.Views[viewName];

        spView.Toolbar =
            @\"<Toolbar Type=\"\"Standard\"\" ShowAlways=\"\"TRUE\"\"/>\";

        spView.Update();

        spSite.AllowUnsafeUpdates = false;
    }
}

更接近，但仍然不好。 这次，它确实修改了视图。我知道这是因为，第二次运行调试器时，我确实注意到SPView.Toolbar属性的值已更改。 但是，当我在SharePoint设计器中打开同一页面时，看不到“ 2”，但看到的默认值为：“ 3”。 除此之外，在浏览器中打开列表视图时，在列表视图页面上看不到工具栏。     

解决方法

这是我必须做的才能使其工作。

        {
            spSite.AllowUnsafeUpdates = true;

            SPList spList = web.Lists[listName];
            SPView spView = spList.Views[viewName];

            SPLimitedWebPartManager spLimitedWebPartManager =

                                                                                  BindingFlags.NonPublic);
                        object[] ensureViewParams = {};

                        Type[] toolbarMethodParamTypes = {Type.GetType(\"System.String\")};
                        MethodInfo setToolbarTypeMethod = view.GetType().GetMethod(\"SetToolbarType\",BindingFlags.Instance |
                                                                                   BindingFlags.NonPublic,null,toolbarMethodParamTypes,null);
                        object[] setToolbarParam = {\"ShowToolbar\"};
                        setToolbarTypeMethod.Invoke(view,setToolbarParam);

                        view.Update();
                    }
                    catch { }
                }
            }

            spSite.AllowUnsafeUpdates = false;
        }
    }
}

    ,请改用

SPView.Toolbar

属性。该属性需要“ 6”个CAML元素，并替换基础CAML片段中的特定XML节点。
