I've a SharePoint 2010 page with a list. The list has several items and a field named "Department" and must filter items based on user's department value retrieved from user profile.

To do this I've created a feature which upon activation adds UserContextFilterWebPart to the page and makes connection between UserContextFilterWebPart and XsltListViewWebPart. After the feature is activated I can see in the page design mode that connection is established but the list gets empty. Then I open web part's menu, choose "Connections" then "Send Filter Values To" and click "List1". When dialog appears I do nothing but only click "Finish" button and it begins to work fine. Can anybody please explain me why the connection begins to work only if I do that manual extra action? What must be done to fix?

I tried different way when List.Views[0].Query property is set to appropriate CAML query and it also works fine. But I'm told that it's not a good approach because of performance and parallel tasks issues. Is it really bad course of action? Below is the code for 2 different approaches. Thanks in advance!

1-s variant with UserContextFilterWebPart:

SPSite Site = new SPSite(URL);
SPWeb Web = Site.OpenWeb();
SPLimitedWebPartManager WPM = Web.GetLimitedWebPartManager(URL, PersonalizationScope.Shared);
XsltListViewWebPart List = WPM.WebParts[0] as XsltListViewWebPart;
UserContextFilterWebPart UCFWP = new UserContextFilterWebPart();
UCFWP.Title = "Current User Filter";
UCFWP.AllowEdit = true;
UCFWP.FilterName = "Current User";
UCFWP.SendEmptyWhenNoValues = true;
UCFWP.AllowClose = true;
UCFWP.ExportMode = WebPartExportMode.All;
UCFWP.AllowConnect = true;
UCFWP.AllowHide = true;
UCFWP.ProfilePropertyName = "Department";
UCFWP.ValueKind = UserContextFilterValueKind.ProfileValue;
UCFWP.ZoneID = "Main";
WPM.AddWebPart(UCFWP, UCFWP.ZoneID, 1);
WPM.SaveChanges(UCFWP);
ConsumerConnectionPointCollection consumerConnections = WPM.GetConsumerConnectionPoints(List);
ConsumerConnectionPoint addConsumerConnPoint = consumerConnections["DFWP Filter Consumer ID"];
ProviderConnectionPointCollection providerConnections = WPM.GetProviderConnectionPoints(UCFWP);
ProviderConnectionPoint addProviderConnPoint = providerConnections["ITransformableFilterValues"];
TransformableFilterValuesToParametersTransformer trans = new TransformableFilterValuesToParametersTransformer();
trans.ConsumerFieldNames = new string[] { "Department" };
trans.ProviderFieldNames = new string[] { "Department" };
SPWebPartConnection newConnection = WPM.SPConnectWebParts(UCFWP, addProviderConnPoint, List, addConsumerConnPoint, trans);
WPM.SPWebPartConnections.Add(newConnection);

2-nd variant with CAML query (intended to be used not in a feature but in a web part):

SPSite Site = new SPSite(URL);
SPWeb Web = Site.OpenWeb();
SPLimitedWebPartManager WPM = Web.GetLimitedWebPartManager(URL, PersonalizationScope.Shared);
XsltListViewWebPart List = WPM.WebParts[0] as XsltListViewWebPart;
SPUser CurrentUser = Web.CurrentUser;
SPServiceContext context = SPServiceContext.GetContext(Site);
UserProfileManager upm = new UserProfileManager(context, false);
UserProfile up = upm.GetUserProfile(CurrentUser.RawSid);
String UserDepartment = up["Department"].Value.ToString();
SPView ListView = Web.Lists["List1"].Views[0];
ListView.Query = "<Where><Eq><FieldRef Name='Department' /><Value Type='Text'>" + UserDepartment + "</Value></Eq></Where>";
ListView.Update();

我在连接两个 Web 部件时遇到了类似的问题。我在这里找到了答案：http: //kvdlinden.blogspot.dk/2011/02/programmatically-connect-two.html

请注意，该帖子描述了如何使用两个 XsltListViewWebParts 来执行此操作。为了在您的情况下使用它，我建议您：

  1. 手动创建连接，
  2. 使用 PowerShell 获取页面的 SPLimitedWebPartManager，
  3. 使用管理器遍历 manager.SPWebPartConnections，
  4. 并找到您的连接的 ProviderConnectionPointID，
  5. 在帖子中显示的代码中使用该 ID。
  6. 还记得设置转换器 - 您也可以从 SPWebPartConnections 中找到它。

下次您激活您的功能时，您应该有一个与您手动创建的连接相同的连接。
