我正在使用 SyncFusion BoldReports ReportVIEwer 并收到以下错误：

数据源具有以下两个或两个：DatasourceReference 和 ConnectionPropertIEs。数据源必须恰好具有这些元素之一。

我们有一个基于 Angular 6 的站点，带有远程 WebAPI。我们要做的是在报表数据到达 ReportAPIController 时加载它

printexposure.component.@R_301_6832@：这部分看起来很可靠，因为它正在调用报告并尝试处理它。

  <bold-reportvIEwer ID="vIEwer" 
  [reportserviceUrl] = "serviceUrl" 
  [reportPath]="Printexpo.rdlc"
  [processingMode] = "Local"
  (AJAXBeforeLoad) = "onAJAXrequest($event)"
  style="wIDth: 100%;height: 600px">
  </bold-reportvIEwer>

在控制器端：
  public class ReportAPIController : APIController,IReportController,IReportLogger

    String parameterjsonData = null;

    //Post action for processing the rdl/rdlc report

    {
      JsonArray = JsonResult;

      {
        //Get clIEnt sIDe JsON custom data,desirialize it
        parameterjsonData = JsonArraY["customData"].ToString();

这是它抛出错误的地方。
我在 API 端检索数据的辅助类：
  public static class ReportDataHelper

    public static List<BoldReports.Web.ReportDatasource> getReportDatasources(int userID,int centrEID,String parameterjsonData)

          return getExpoPrintDatasources(userID,parameterjsonData);

        case "":

      public bool allowPrintRevIEws { get; set; }
      public int userID { get; set; }

    }

    private static List<BoldReports.Web.ReportDatasource> getExpoPrintDatasources(int userID,String parameterjsonData)
    {

      var expoParams = JsonConvert.DeserializeObject<CaseReportParameters>(parameterjsonData);

      bool EditMode = false;

      var exposureDetails = new ExposureBL().GetExposureDetails(expoParams.CasEID,userID,EditMode,expoParams.allowPrintPHI);

      // flatten out lab tests and responses
      var LabTestList = new List<LabTest>();
      foreach (var lab in exposureDetails.LabList)
      {
        if (lab.LabTestList.Count > 0)

      return r;

这是我的 printexpo.rdlc 中的 xml，当我创建它时，它位于 Project.services.DTO.DTO 中，因此我可以获得数据类“Callinfo”的架构，然后我将其转移到 Project.services .WebAPI。我认为这应该不是问题，因为其中的报告文件和数据集只是一个架构，我正在通过上面的 API 加载数据。

@H_772_13@
我只发现了一个与 SyncFusion 类似的问题：https://www.syncfusion.com/forums/162953/the-data-source-x-has-both-or-neither-of-the-following-datasourcereference-and，他们告诉小伙子在项目中包含 BoldReport 的扩展，我也这样做了，但无济于事。不知道它应该做什么，哈哈。
上面的报告是简化的，还有很多内容要处理，我很困惑，如果能提供任何帮助，我们将不胜感激。
我是报告设计的新手，是否可以删除/忽略数据源？当我自己在 ReportAPIController 中加载数据集时？
 
解决方法

        
您必须在客户端应用程序中将报表查看器处理模式设置为本地。对于处理模式属性值，您必须绑定在打字稿文件中。您能否在您的应用程序中使用以下代码片段。
app.component.html 文件
<bold-reportviewer id="viewer"  
  [reportserviceUrl] = "serviceUrl"  
  [reportPath]="reportPath" 
  [processingMode] = "Local" 
  (ajaxBeforeLoad) = "onAjaxrequest($event)" 
  style="width: 100%;height: 600px"> 
  </bold-reportviewer> 
@H_772_13@
app.component.ts 文件
  export class AppComponent { 
  public serviceUrl: String; 
  public reportPath:string; 
  public Local:string; 

    constructor() { 
     this.reportPath = 'Printexpo.rdlc' 
     this.Local="Local" 
    } 
}
