microsoft reportviewer

Hi,

I'm running on ASP.NET 4 , I just upgraded my report-viewer from 9.0 to 10.0 .
Everything still works fine on my local PC, but when I upload it to the server, i can't see the report, no error is shown. I'm not sure where the problem is hiding.

This is my code :

d Code:

For Each row As GridViewRow In GridView1.Rows ' Access the CheckBox 
                Dim cb As CheckBox = row.FindControl("CheckBox2")
                If cb IsNot Nothing AndAlso cb.Checked Then 
                    ReportViewer1.Visible = True
                    atLeastOneRowDeleted = True ' First, get the ProductID for the selected row 
                    Dim ID As Integer = (GridView1.DataKeys(row.RowIndex).Value) ' "" the row
 
                    bb &= String.Format("{0},", ID)
 
 
                End If
            Next ' Show the Label if at least one row 
            actionsDropDownList.Text = ""
 
 
 
            ReportViewer1.Reset()
            ReportViewer1.ProcessingMode = ProcessingMode.Local
 
            Dim rep As LocalReport = ReportViewer1.LocalReport
            rep.ReportPath = "invoice.rdlc"
 
            Dim ds As DataSet = GetSalesData("InvoiceData")
 
            'Create a report data source for the sales order data
            Dim dsSalesOrder As New ReportDataSource()
            dsSalesOrder.Name = "InvoiceData_invoice"
            dsSalesOrder.Value = ds.Tables("InvoiceData")
            '+++++++++++++++++++++++++++++++++++++++++++++ Send Parameter +++++++++++++++++++++++++++++
            Dim params(0) As Microsoft.Reporting.WebForms.ReportParameter
 
            Dim p As Microsoft.Reporting.WebForms.ReportParameter
            p = New Microsoft.Reporting.WebForms.ReportParameter("searchcriteria", searchcriteria.Text)
 
            params(0) = p
 
            ReportViewer1.LocalReport.SetParameters(params)
            '+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
            rep.DataSources.Add(dsSalesOrder)

tt Code:

Private Function GetSalesData(ByVal sourcetable As String)
 
 
        Dim len As Integer
        Dim bbc As String
 
        len = bb.Length
        bbc = bb.Remove(len - 1, 1)
 
        Dim ds As New DataSet
 
        Dim sqlSalesData As String = "SELECT * FROM   xxxxxxx where ID in(" & bbc & " ) order by datee"
 
        Using connection As New SqlConnection(ConfigurationManager.ConnectionStrings("xxxxxx").ToString)
 
            Dim command As New SqlCommand(sqlSalesData, connection)
 
            Dim salesOrderAdapter As New SqlDataAdapter(command)
 
            salesOrderAdapter.Fill(ds, sourcetable)
 
            salesOrderAdapter.Dispose()
 
            command.Dispose()
 
        End Using
 
        Return ds
 
    End Function

thanks
