Question

我在SharePoint Designer中创建了一个简单的自定义页面布局，在每个区域添加了几个Web部件区域和自定义Web部件。

这些Web部件具有自定义提供者 - 使用者接口集。我在SharePoint Designer中配置了Web部件之间的连接（使用“添加连接”向导），并保存了页面布局。

之后，我检查了布局并在SP的网络界面中批准了它。

最后，我根据布局创建了一个发布页面，但未设置Web部件之间的连接。我可以手动设置连接，它工作正常，但我希望在我根据布局创建的每个页面上自动设置连接。

这是预期的行为吗？如果是这样，有没有办法以编程方式或声明方式自动配置连接？

我缺少一步吗？

可以在SharePoint中设置连接，但不是那么容易。以下是我项目的代码。首先，我们需要一些方法来为消费者领域和提供者领域创建变换器：

private TransformableFilterValuesToParametersTransformer CreateTransformer(String consumerFieldName, String providerFieldName)
        {
            TransformableFilterValuesToParametersTransformer filterToParameterTransformer =
                new TransformableFilterValuesToParametersTransformer();
            // The private fields '_consumerFieldNames' and '_providerFieldNames' must be set for the web part connection to work.
            // Having reflected the TransformableFilterValuesToParametersTransformer it seems that the only place this is set is within a
            // nested wizard class (this seems to be the wizard that runs when the connection is created via the SharePoint UI) so although
            // this is not pretty it looks to be the only way...

            try
            {
                string[] _consumerFieldNames = new string[1];
                _consumerFieldNames[0] = consumerFieldName;
                FieldInfo conFld = typeof(TransformableFilterValuesToParametersTransformer).GetField("_consumerFieldNames", BindingFlags.Instance | BindingFlags.NonPublic);
                conFld.SetValue(filterToParameterTransformer, _consumerFieldNames);
                string[] _providerFieldNames = new string[1];
                _providerFieldNames[0] = providerFieldName;
                FieldInfo prvFld = typeof(TransformableFilterValuesToParametersTransformer).GetField("_providerFieldNames", BindingFlags.Instance | BindingFlags.NonPublic);
                prvFld.SetValue(filterToParameterTransformer, _providerFieldNames);
            }
            catch
            {
                throw new Exception("Unexpected internal definition for 'TransformableFilterValuesToParametersTransformer'. Please amend private member access code.");
            }
            return filterToParameterTransformer;
        }

现在创建连接：

TransformableFilterValuesToParametersTransformer transformer = CreateTransformer("ConsumerFieldInternalName", "ProviderFieldInternalName");

            ProviderConnectionPointCollection pcpc = mgr.GetProviderConnectionPoints(providerWebPart);
            ConsumerConnectionPointCollection ccpc = mgr.GetConsumerConnectionPoints(consumerWebPart);
            mgr.SPConnectWebParts(
               providerWebPart, pcpc[0],
                consumerWebPart,
                ccpc[0],
                transformer
                );

mgr是特定视图页面的SPLimitedWebPartManager实例。
