Hi all,
I'm using VS2010 web application. I'm trying to use subreport with
reportviewer. The report is working with my machine, it returns the main and
sub report. But when moved to web-server, the main report display, not the
subreport and no error indicate. I did something like this with VS2005, I did
not have any problems. Here is my coding:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load

Dim ReportViewer1 As New ReportViewer

Dim rptDataSourceMain As New ReportDataSource("dsSRC",
GetDataSet("p_SRC_completed_main").Tables(0))

With ReportViewer1
.ProcessingMode = ProcessingMode.Local
.AsyncRendering = False
.LocalReport.ReportPath = "content\SRC.rdlc"
.LocalReport.DataSources.Clear()
.LocalReport.DataSources.Add(rptDataSourceMain)
End With

' HANDLE the sub-report
AddHandler ReportViewer1.LocalReport.SubreportProcessing, AddressOf
SetSubDataSource

ReportViewer1.LocalReport.Refresh()

Try
Dim deviceInfo As String = "<DeviceInfo>" & _
"<OutputFormat>PDF</OutputFormat>" & _
"<PageWidth>8.5in</PageWidth>" & _
"<PageHeight>11in</PageHeight>" & _
"<MarginTop>0.5in</MarginTop>" & _
"<MarginLeft>0.75in</MarginLeft>" & _
"<MarginRight>0.4in</MarginRight>" & _
"<MarginBottom>0in</MarginBottom>" & _
"</DeviceInfo>"

Dim formatPDF As Byte() =
ReportViewer1.LocalReport.Render("PDF", deviceInfo, Nothing, Nothing,
Nothing, Nothing, Nothing)

Response.Clear()
Response.ContentType = ""
Response.AddHeader("content-disposition", "attachment;
filename=SRC.pdf")
Response.BinaryWrite(formatPDF)
Response.End()

Catch ex As Exception
Response.Write("ERROR:" & ex.ToString)

End Try

End Sub

'
=========================================================================
' Handle subreport call dataset
'
=========================================================================
Protected Sub SetSubDataSource(ByVal sender As Object, ByVal e As
SubreportProcessingEventArgs)

e.DataSources.Add(New ReportDataSource("dsSRCsub",
GetDataSet("p_SRC_completed_sub").Tables(0)))

End Sub

'
=========================================================================
' Get the dataset to reportviewer (both main and sub) without
SQLdatasource
'
=========================================================================
Protected Function GetDataSet(ByVal spName As String) As DataSet

GetDataSet = Nothing

Dim cnnPath As String =
ConfigurationManager.ConnectionStrings("cnPath").ConnectionString
Dim cnn As New SqlConnection(cnnPath)
Dim cmd As New SqlCommand
Dim ds As New DataSet
Dim da As SqlDataAdapter

With cmd
.Connection = cnn
.CommandType = CommandType.StoredProcedure
.CommandText = spName
.Parameters.Add("@util_id", SqlDbType.Int).Value = 1990
End With
Try
cnn.Open()
da = New SqlDataAdapter(cmd)
da.Fill(ds)
GetDataSet = ds

Catch ex As Exception
Response.Write("ERROR: " & ex.ToString)
GetDataSet = Nothing

Finally
cmd.Dispose()
cnn.Close()
cnn.Dispose()

End Try

End Function

Any solutions for this problems in VS2010.
Thanks.
