Can anyone give me an example of passing a multivalue parameter from a winform  to a telerik report.
Can it even be done ?

I have spent 3 days now trying to get it working with windows report viewer and devexpress reports without success.
All i want to do is allow users to select multiiple records in a gridview and passthe values to a report
So it creates an invoice. I cant believe its soo hard.
Having a 2 week deadline to get this working or its getting developed in Lotus notes and im not even sure if it can be done.

Any help on this would be appreciated as i am tearing what little hair i have left out with it.


Thanks in advance

Hi martin,

If you are asking about Telerik Reporting then setting a Multivalue Report Parameter value programmatically from Windows Forms Report Viewer is quite easy as shown in the following code snippet:

public Form1()
{
    InitializeComponent();
 
    var report1 = new ClassLibrary2.Report1();
    Int64[] values = {1,2,3};
    report1.ReportParameters[0].Value = values;
    reportViewer1.Report = report1;
    reportViewer1.RefreshReport();
}

If you are asking about a competitor's product then you are in the wrong forum.

Sincerely yours,

Thanks for your reply Peter I will give it a go later.
It is meant for the telerik  forums as i am looking for a solution and have tried other vendors products without success.

In case it helps anyone, this also worked for me using web forms:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ShowReport.aspx.cs" Inherits="ShowReport" %>
 
<%@ Register Assembly="Telerik.ReportViewer.WebForms, Version=4.1.10.714, Culture=neutral, PublicKeyToken=a9d7983dfcc261be"
  Namespace="Telerik.ReportViewer.WebForms" TagPrefix="telerik" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<head runat="server">
  <title></title>
  <link href="styles/main.css" rel="Stylesheet" />
</head>
<body>
  <form id="form1" runat="server">
  <telerik:ReportViewer ID="rv" runat="server" Height="600px" Width="633px">
  </telerik:ReportViewer>
  </form>
</body>
</html>

and

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
 
public partial class ShowReport : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        var report = new TelerikReports.WeberLetters();
        report.ReportParameters["ID"].Value = new Int32[] { 13, 345, 999 };
        rv.Report = report;
    }
}
