Hi there, I have asp.net page with Multi select listbox (Northwind customers table) I created report on the server called Customers (patamerer = In(@Company)) When user pick few customers name and click submit the page store the values on label And then pass into the report with the following code Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click 'Get Customers from Listbox multi select Dim i As Integer Dim s As String = Trim(Label1.Text) Label1.Text = " " For i = 0 To ListBox1.Items.Count - 1 If ListBox1.Items(i).Selected Then Label1.Text = Label1.Text & ListBox1.Items(i).Text & vbCrLf End If Next 'Pass multi value into the report Dim colRP As New System.Collections.Generic.List(Of Microsoft.Reporting.WebForms.ReportParameter) colRP.Add(New Microsoft.Reporting.WebForms.ReportParameter("Company", UCase(Label1.Text.TrimStart))) ReportViewer1.ServerReport.ReportServerUrl = New Uri("http://localhost/ReportServer") ReportViewer1.ServerReport.ReportPath = "/Northwind/Customers" ReportViewer1.ServerReport.SetParameters(colRP) ReportViewer1.ServerReport.Refresh() End Sub Now everything works fine when the ShowParameterPrompts is = True Then you need to click View Report button But when the ShowParameterPromts is = False The report is not render (the parameters value are there) My goal is to not show the Parameter on the report instead Pass the parameter directly from asp.net How do I make the report render? after the parameters passed Thanks Oded Dror

Oded shalom We call reports in that way, see if that helps you Dim RetVal As Long RetVal = Shell("c:\progra~1\Intern~1\iexplore.exe http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fFolderReports%2frptReportName&rs%3aCommand=Render&ParamName=" & param_variable, vbMaximizedFocus) Best Regards, Uri Dimant SQL Server MVP http://dimantdatabasesolutions.blogspot.com/ http://sqlblog.com/blogs/uri_dimant/
