• How to: Use a Custom XtraReport Descendant as the Base Class for New Reports 如何:使用自定义报表后代作为新报表的基类


    In certain scenarios you may want to customize the base reports class to provide custom functionality available in all new reports. This topic describes how you can register a custom XtraReport descendant that will be used when an end-user creates a report at runtime.

    在某些情况下,您可能需要自定义基本报表类,以提供所有新报表中可用的自定义功能。本主题介绍如何注册自定义 XtraReport 后代,该后代将在最终用户在运行时创建报表时使用。

    Assume you have the following custom report class.

    假设您具有以下自定义报表类。

    public class MyXtraReport : XtraReport {
       // ...
     }

    Do the following to use MyXtraReport instead of XtraReport in new user-defined reports.

    • In the module project, inherit the ReportsStorage class and override the CreateReport method.

    执行以下操作,在新的用户定义的报表中使用 MyXtraReport 而不是 XtraReport。

    • 在模块项目中,继承报表存储类并重写创建报表方法。

      using DevExpress.ExpressApp.ReportsV2;
      // ...
      public class CustomReportStorage : ReportsStorage {
          protected override XtraReport CreateReport() {
              return new MyXtraReport();
          }
      }
    • In the module's constructor, assign an instance of your ReportsStorage descendant to the static ReportDataProvider.ReportsStorage property.

    • 在模块的构造函数中,将报表存储后代的实例分配给静态报表数据提供程序.报告存储属性。

      using DevExpress.ExpressApp.ReportsV2;
      // ...
      public sealed partial class MySolutionModule : ModuleBase {
          public MySolutionModule() {
              // ...
              ReportDataProvider.ReportsStorage = new CustomReportStorage();
          }
          // ...
      }

    To check the result, run the application and create a report.

    要检查结果,请运行应用程序并创建报表。
