.rdlc报告势必对象数据源的三层应用 [英] .rdlc reporting bound to Object Data Source in Three layer Application
问题描述
我有以下的情况，我在asp.net应用程序中的报表层（单机）（未经网站，这意味着没有APP_ code文件夹存在），我想只是为了创建对象数据源取在一个单独的层中的对象（可以从数据访问层说的），然后使用该对象的数据源创建报表，我已经花了我整整一天周围的工作，吨工作围绕的和在网络上的文章，但不不提我真正想做的事情，任何的答案是appriciated ...
i have the following situation, i have a Reporting layer(stand alone) in asp.net application(NOT website, this means NO App_Code folder exists), and i want just to create Object Data Source to take an Object in a separate layer(lets say from Data Access Layer), and then to use that Object Data Source to create a report, i have spent my whole day working around that, tons of work around's and articles on the web, but does not mention what i really want to do, any answer is appriciated...
只是为了让事情更清楚在这里，假设以下：
just to make things more clear here, assume the following:
我与follwoing层的解决方案，
i have a solution with the follwoing layers,
- 在UI
- 报告（有没有员工反对）只是一个参考
- 商业逻辑
- 在数据访问层（雇员 - >装getEmployees（）
我需要的是如上面提到的，我想从报告层，采取Employee对象从DAL创建对象数据源，然后用它的getEmployees方法被添加到 报告中，我认为它更清楚了吧，因为也报表层不具有APP_ code文件夹。
all i need is as mentioned above, i want to create Object Data Source from Reporting layer, to take Employee object from DAL, and then use it's GetEmployees method to be added to report, i think its more clear now, since also Reporting layer has NO App_Code folder.
推荐答案
的方式我一直都做的是通过创建一个有一个List类型的属性的类。我dhave一个名为LoadReport方法（PARAMS ......）在这个类中，我会打电话GetEmployess来填充我的财产。
The way Ive been doing it is by creating a class that has a property of type List. I dhave a method called LoadReport(params......) in this class where I would call GetEmployess to populate my property.
我会再添加一个新的数据集，在报表设计器，选择绑定到对象，并选择我创建的类。一旦完成了数据集将让你展开列表属性，你可以将不同的字段拖到设计师。
I would then add a new Dataset in the report designer, selecting to bind to Object, and selecting the class i created. Once finished the dataset will allow you to expand the List property where you can drag different fields onto the designer.
