Hello,

I have an ASP.NET application that contains reports. I am not allowed to
use Crystal, so I decided to use .NET's reporting tool. My problem is that
the report viewer does not show in the browser, neither I am receiving any
error messages. Below is the code. Any help will be really appreciated.

Thank you very much for your help.

Carlos


Private Sub Show_Report(ByVal From_rpt_date As Date, ByVal To_rpt_date
As Date)

'Set the processing mode for the ReportViewer to Local
ReportViewer1.Reset()
ReportViewer1.ProcessingMode =
Microsoft.Reporting.WebForms.ProcessingMode.Local
ReportViewer1.Visible = True

Dim LocalRpt As New Microsoft.Reporting.WebForms.LocalReport
LocalRpt.ReportPath = "~/MyReport.rdlc"

'name of connection string as stored in web.config
Dim s_connString As String = "MyConnString"
Dim cn As New
SqlConnection(ConfigurationManager.ConnectionStrings(s_connString).ConnectionString)

' "MyStoredProcedure" is the name of the stored procedure
Dim cmd As New SqlCommand("MyStoredProcedure", cn)
cmd.CommandType = Data.CommandType.StoredProcedure

' "@from_eff_date" and "@to_eff_date" are the names of
'Stored procedure parameters
cmd.Parameters.Add("@from_eff_date", Data.SqlDbType.DateTime).Value
= From_rpt_date
cmd.Parameters.Add("@to_eff_date", Data.SqlDbType.DateTime).Value =
To_rpt_date
cmd.CommandTimeout = 120

'declare and configure SqlDataAdapter
Dim da As New SqlDataAdapter
da.SelectCommand = cmd

' MyDataSet is the name of the DataSet
Dim ds As New MyDataSet
da.Fill(ds, "MyDataTable")

' "MyDataTable" is the name of the DataTable
Dim rds As New Microsoft.Reporting.WebForms.ReportDataSource
rds.Name = "MyDataTable"
rds.Value = ds.Tables("MyDataTable")

' Add ReportDataSource to Local
LocalRpt.DataSources.Add(rds)

LocalRpt.Refresh()

End Sub
