VB.NET Error : "The source of the report definition has not been specified." on Report Viewer Parameter Setting
提问by Jacob Siemaszko
By VS2012 i connect to the reporting webservice and need to load the "handShake" Parameter into my report which is a ServerReport, not a LocalReport.
通过 VS2012，我连接到报告 Web 服务，需要将“handShake”参数加载到我的报告中，它是一个 ServerReport，而不是一个 LocalReport。
This is my Page_Init Code :
这是我的 Page_Init 代码：
If (Request.QueryString("handShake") = Nothing) Then
Response.Redirect("~/AccessDenial.aspx")
End If
'' Set up the credentials
ReportViewer1.ServerReport.ReportServerUrl = New Uri(ConfigurationManager.AppSettings("MyReportServerPath"))
ReportViewer1.ServerReport.ReportServerCredentials = New MyReportServerCredentials()
Dim objparameter As Microsoft.Reporting.WebForms.ReportParameter
objparameter = New Microsoft.Reporting.WebForms.ReportParameter("handShake", Request.QueryString("handShake").ToString)
ReportViewer1.ServerReport.SetParameters(objparameter)
The last line of code gives me the Error :
最后一行代码给了我错误：
The source of the report definition has not been specified."
On lots of Forums they say I need to change serverReport to localReport but this is not the case...
在很多论坛上，他们说我需要将 serverReport 更改为 localReport 但事实并非如此...
Lots of Thanks for help!
非常感谢您的帮助！

In addition to
此外
.ServerReport.ReportServerUrl
and
和
.ServerReport.ReportServerCredentials
you also have to specify
你还必须指定
.ServerReport.ReportPath
that points to actual report in SSRS. This is report definition (ordinary an uploaded RDL) that you set the parameters for. E.g.
指向 SSRS 中的实际报告。这是您为其设置参数的报告定义（通常是上传的 RDL）。例如
ReportViewer1.ServerReport.ReportPath = "/My Reports/Summary Report"
