RDLC文件中的子报表 [英] Subreport in RDLC file

问题描述

在VS2010中生成报告时遇到一个问题.我正在使用RDLC.我的任务是生成一个报告，该报告应在报告的顶部显示客户详细信息，例如姓名，联系电话，电子邮件ID等.

I have one problem in generating Reports in VS2010. I am using RDLC. My task is to generate a report where it should show customer details like Name, Contact number, Email Id etc in the top portion of the report.

在正文部分，应显示列表保留详细信息.

In the body section it should show the list reservation details.

我的对象结构如下:

CustomerDetails:
        Name
        Age
        ContactNumber
        Email Id
        List<ReservationDetails>

ReservationDetails
        FromDate
        ToDate
        Period
        Amount

我不知道如何在子报表中呈现列表.它不是动态的，我在初始加载本身中获得了所有详细信息. 我将报告分为两个部分，首先(父级)是为了显示常见细节.子报表将显示预留"详细信息列表.

I do not know how to render the List in subreport. It is not dynamic and I got all the details in initial load itself. I split the report into tow section, First (parent) is to show the common details. and Subreport is to show the list of Reservation details.
