Question

我正在配置发布页面作为功能的一部分，并在页面上放置单个列表视图Web部件（请参阅下面的代码）。这一切都完美无缺。

<Elements>
    <Module>
        <File Path="default.aspx" Url="BulletinBoard.aspx" Type="GhostableInLibrary" IgnoreIfAlreadyExists="TRUE">
            <Property Name="Title" Value="Bulletin Board" />
            <Property Name="PublishingPageLayout" Value="~SiteCollection/_catalogs/masterpage/ListNewsletterStyle.aspx" />
            <Property Name="ContentType" Value="Page" />
            <Property Name="PublishingPageImage" Value="" />
            <View List="Lists/BulletinBoard" BaseViewID="2" WebPartZoneID="Main" WebPartOrder="1">
                <![CDATA[
                <webParts>
                    <webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
                        <metaData>
                            <type name="Microsoft.SharePoint.WebPartPages.XsltListViewWebPart,Microsoft.SharePoint,Version=14.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c" />
                            <importErrorMessage>Cannot import this Web Part.</importErrorMessage>
                        </metaData>
                        <data>
                            <properties>
                                <property name="Title">Active Announcements</property>
                                <property name="ChromeType">None</property>
                            </properties>
                        </data>
                    </webPart>
                </webParts>
                ]]>
            </View>
        </File>
    </Module>
</Elements>

唯一的问题是，每次通过Visual Studio重新部署我的功能时，列表视图Web部件都会重复（即另一个部件被添加到Web部件区域）。

此问题仅出现以影响带有＆lt; View ...＆gt;的Web部件标签。使用＆lt; AllUsersWebPart ...＆gt;配置的Web部件标签没有重复。

如何防止这种情况？

Answer 1

您可以添加功能接收器并添加Web部件（如果尚不存在），而不是在XML中添加Web部件。标签是什么意思？

查看Waldek Mastykarz的blog entry。它下面的C＃代码应该与您要查找的类似。

using (SPSite site = new SPSite("http://sharepoint"))
{
  SPList list = site.GetCatalog(SPListTemplateType.MasterPageCatalog);
  SPListItemCollection items = list.Items;
  List<string> webParts = new List<string>();

  // find the right Page Layout
  foreach (SPListItem item in items)
  {
    if (item.Name.Equals("CustomPageLayout.aspx",
      StringComparison.CurrentCultureIgnoreCase))
    {
      SPFile file = item.File;
      // get the Web Part Manager for the Page Layout
      SPLimitedWebPartManager wpm =
        file.GetLimitedWebPartManager(PersonalizationScope.Shared);
      // iterate through all Web Parts and remove duplicates
      while (wpm.WebParts.Count > 0)
      {
        StringBuilder sb = new StringBuilder();
        XmlWriterSettings xws = new XmlWriterSettings();
        xws.OmitXmlDeclaration = true;
        XmlWriter xw = XmlWriter.Create(sb, xws);
        System.Web.UI.WebControls.WebParts.WebPart wp =
          wpm.WebParts[0];
        wpm.ExportWebPart(wp, xw);
        xw.Flush();
        string md5Hash = getMd5Hash(sb.ToString());
        if (webParts.Contains(md5Hash))
          wpm.DeleteWebPart(wp);
        else
          webParts.Add(md5Hash);
      }
    }
  }
}

SharePoint 2013用户请注意。您应该将ReplaceContent = True添加到标记中。将解决重复的webpart问题。
