Hi Everyone,

I'm using VB.Net 2012 and Telerik Reporting V:6.1.12.611. My question is, How to call all reports to display in Master Report using SubReport?

I'm having a problem of creating Master Report in order to view all my report within a subReports. I retrieved the information from different tables and send to datagridview in order manipulate the data once I done send to Generic List contains a series of CLASS objects. To View one report works 100%, but when I try to used sub-report to call a report nothing appear on the report. I created empty dataset link to the CLASS and LIST OF works perfect only SubReport and configuration & Parameters which is failing me.

I try this code is not displaying data within a subReport

Dim rpt As New rptMasterReport()
'retrieving data from the database and send data to Generic List contains a series of CLASS objects
setMonthlyTransReport()
Dim subRpt As New Telerik.Reporting.SubReport()
Dim rptSource As New Telerik.Reporting.InstanceReportSource()
rptSource.ReportDocument = rpt
rptSource.Parameters.Add(New Telerik.Reporting.Parameter("R1", "=Fields.R1"))
subRpt.ReportSource = rptSource
'bind datasource with Generic List contains a series of CLASS objects
rpt.DataSource = lstDailyTicketsRevenue
' Assigning the report to the report viewer.
frmReportViewer.ReportViewer1.ReportSource = rptSource
                          
' Calling the RefreshReport method for WinForms application.
frmReportViewer.ReportViewer1.RefreshReport()
'call form viewr
frmReportViewer.Show()

Any Help will be appreciated.
Thanks!
