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。
