未指定报告定义的来源



这是我的代码

the source of the report definition is not specified

this is my code

With Me.ReportViewer1.LocalReport

                ' Report path
                .ReportPath = Application.StartupPath & "C:\Users\noble\Desktop\WindowsApplication2\WindowsApplication2\Report1.rdlc"
                ' ReportViewer1.LocalReport.ReportPath = "C:\Users\noble\Desktop\WindowsApplication2\WindowsApplication2\Report1.rdlc"
                .DataSources.Clear()
            End With

            ' ----------------------------------------------------
            ' Datasource for the main report (where price > 200)
            ' ----------------------------------------------------
            Dim SQL As String = "SELECT Voter.SrNo, Voter.YadiNo, Voter.FullName, Voter.Gender, Voter.Age, Voter.HouseNo, Voter.Address, Voter.CardNo FROM Voter WHERE yadino=1"
            Using da As New OleDbDataAdapter(SQL, My.Settings.trialConnectionString)
                da.SelectCommand.Parameters.Add("@yadino", OleDbType.Integer).Value = 200

                Using ds As New DataSet
                    da.Fill(ds, "voter")

                    ' You must use the same name as defined in the report 
                    ' Data Source Definition
                    Dim rptDataSource As New ReportDataSource("dsReport_products", ds.Tables("voter"))
                    Me.ReportViewer1.LocalReport.DataSources.Add(rptDataSource)
                    Me.ReportViewer1.Reset()
                End Using

            End Using

推荐答案

您好basurajkumbhar，

通过查看您的代码，我认为您的ReportPath没有获得路径。据我所知，路径在路径字符串之前用'@'符号指定。为什么你要使用这个？$
Application.StartupPath&C：\ Users \ noble \Desktop \ WindowsApplication2 \ WindowsApplication2 \ Report1rdlc？



我认为这是不正确的。



希望这个建议能够奏效。

谢谢

Hi basurajkumbhar ,
By looking your code I think that your ReportPath is not getting the path. As far as I know the path is specified with '@' sign prior the path string. And why you are using this
Application.StartupPath & "C:\Users\noble\Desktop\WindowsApplication2\WindowsApplication2\Report1.rdlc"?

I think this is not correct.

Hope this suggestion would work.
