将PPS过滤器WebPart（提供商）连接到自定义Webpart（消费者）时遇到问题。
当前实施：
public partial class SQLTextWebPart : WebPart , Microsoft.SharePoint.WebPartPages.IFilterValues {
private Microsoft.SharePoint.WebPartPages.IFilterValues _provider = null;
[ConnectionConsumer("Filter Consumer", "FilterConsumer")]
public void FilterValueConsumer ( Microsoft.SharePoint.WebPartPages.IFilterValues Provider ) {
_provider = Provider;
}
protected override void OnPreRender ( EventArgs e ) {
EnsureChildControls();
if ( _provider != null ) {
lblFilterValue.Text = _provider.ParameterName + ": " + _provider.ParameterValues[ 0 ];
}
////Execute BaseClass OnPreRender - Last
//base.OnPreRender( e );
}
#region IFilterValues Members
public string ParameterName {
get { throw new NotImplementedException(); }
}
public ReadOnlyCollection<string> ParameterValues {
get { throw new NotImplementedException(); }
}
public void SetConsumerParameters ( ReadOnlyCollection<Microsoft.SharePoint.WebPartPages.ConsumerParameter> parameters ) {
throw new NotImplementedException();
}
#endregion
}
然后当我尝试将连接发送到SQLTextWebPart或从PPS过滤器获取连接时，弹出窗口并出现CorrelationID。对日志文件进行了PowerShell查询并获得了此结果。仍然习惯于SharePoint的格式化及其异常处理，所以也许有人更多地了解格式可以帮助理解它。

最后解决了我的所有连接问题，并在SharePoint Exchange中编写了Q＆amp; A样式帖子，Visual Web Part as consumer of PPS Filter Provider。
如果其他人登陆此帖子，他们应该能够阅读有关成功实施的步骤。
