本主题介绍如何访问报表 V2 模块用于在ASP.NET应用程序中创建和修改用户定义的报表的 ASPx 报告设计器控件。

In this topic, it is assumed that you have an XAF application that uses the Reports V2 Module, and you have created one or more reports (see Reports V2 Module Overview).

在本主题中，假定您有一个使用报表 V2 模块的 XAF 应用程序，并且您创建了一个或多个报表（请参阅报表 V2 模块概述）。

The control is wrapped into a View Item that is displayed in the Detail View. The identifier of this View is specified by using the ReportsAspNetModuleV2.ReportDesignDetailViewWebName constant. So, to directly access the control's properties and events, use the following View Controller.

该控件将换行到显示在"详细信息视图"中的视图项中。此视图的标识符通过使用报告AspNetModuleV2.报告设计细节视图WebName常数指定。因此，要直接访问控件的属性和事件，请使用以下视图控制器。

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.ReportsV2.Web;
using DevExpress.XtraReports.Web;
// ...
public class CustomizeReportDesginerController : ViewController<DetailView> {
    public CustomizeReportDesginerController() {
        TargetViewId = ReportsAspNetModuleV2.ReportDesignDetailViewWebName;
    }
    protected override void OnActivated() {
        base.OnActivated();
        ReportDesignerDetailItem designerDetailItem =  View.GetItems<ReportDesignerDetailItem>()[0];
        designerDetailItem.ControlCreated += delegate(object sender, EventArgs e) {
            ASPxReportDesigner designerControl = designerDetailItem.ReportDesigner;
            // Place you code that accesses the designer control here.
        };
    }
}
