无法创建rdlc报告 [英] Cannot create rdlc report

问题描述

我刚刚开始RDLC报告，但这吓坏了我.

我有一个业务层类，其中方法返回对象列表.我首先创建了一个报告模板(.rdlc文件)，并提到了该特定方法.我将字段放入对象中，并将其拖到报表设计器中的值部分.

接下来，我创建了一个Web表单，然后在该Web表单中放置了一个scriptManager和reportViewer.我选择了rdlc模板并将其绑定到我的reportviewer.数据集是使用ObjectDataSource自动绑定的.我不必绑定数据集.

 <   rsweb:ReportViewer     ID   ="     runat   =" 服务器" 字体名称   Verdana" 字体大小  ="     WaitMessageFont名称  ="  span>    WaitMessageFont-Siz e   ="  >> 
        <   LocalReport     ="   Report3.rdlc" <  数据源 > 
                <   rsweb:ReportDataSource    名称  ="   DataSourceId    ObjectDataSource1 " <  > 
            <  /DataSources  > 
        <  /LocalReport  > 
    <  /rsweb:ReportViewer  > 

    <   asp:ObjectDataSource    运行  ="   SelectMethod    getAllFaculties "  TypeName    ERM.BLL.AcademicSetup.FacultyBL"  ID   ="  >  <  /asp:ObjectDataSource  >  

当我运行此应用程序时，我得到了他的错误

报表处理期间发生错误.无法为数据集"DataSet1"创建数据读取器.

注意:如果我将ObjectDataSource绑定到GridView，它会完美地工作.我在做什么错?

I have just started RDLC reports but this is freaking me out.

I have a business layer class where a method returns a list of objects. I first created a report template (.rdlc file) and I mentioned that particular method. I got the fields in the object and I dragged them to the values portion in the report designer.

Next, I created a webform, and then I put a scriptManager and reportViewer in the webform. I chose my rdlc template and bound it to my reportviewer. The dataset was automatically bound using an ObjectDataSource. I did not have to bind the dataset.

<rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt">
        <LocalReport ReportPath="Report3.rdlc">
            <DataSources>
                <rsweb:ReportDataSource Name="DataSet1" DataSourceId="ObjectDataSource1"></rsweb:ReportDataSource>
            </DataSources>
        </LocalReport>
    </rsweb:ReportViewer>

    <asp:ObjectDataSource runat="server" SelectMethod="getAllFaculties" TypeName="ERM.BLL.AcademicSetup.FacultyBL" ID="ObjectDataSource1"></asp:ObjectDataSource>

When I run this application, I get his error

An error has occurred during report processing. Cannot create a data reader for dataset ''DataSet1''.

Note: if I bind my ObjectDataSource to a GridView, it works perfectly. What am I doing wrong?
