Hello Mridul,

Here is a sample:

Copy Code

<asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server">

    <script runat="server">

        public override void VerifyRenderingInServerForm(Control control)
        {
            // to avoid the server form (<form runat="server">) requirement
        }

        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);

            // bind the report viewer
            Telerik.Reporting.Report rpt = new ClassLibrary1.Report1();
            rpt.ReportParameters["Parameter1"].Value = ViewData["reportParam"];
            ReportViewer1.Report = rpt;
        }
    </script>
    <telerik:ReportViewer runat="server" ID="ReportViewer1" />
</asp:Content>

HomeController:

Copy Code

public ActionResult Index()
        {
            ViewData["Message"] = "Welcome to ASP.NET MVC!";
            ViewData["reportParam"] = "my data";
            return View();
        }

Hey Steve,

Thanks for your reply.

I have implemented this functionality. I have few more question:
-> I have to pass user inputs to report and assign them to report parameters on my own button Click Event in MVC.
-> I did try to design a constructor for Report  and call that and provide user inputs and then i did call RefreshReoprt() function to get report but i'm unable to use that new constructor.
-> Please let me know how to render report with new user inputs on my own button click event.  

Have a look on Code Block: 

// Report View Code
<script runat="server">
        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
            ReportViewer1.Report = new Test.Reports.Report1();
        }

        protected void ButtonShow_Click(object sender, EventArgs e)
        {
            ReportViewer1.Report = new Test.Reports.Report1(TextSearchName.Value);
            ReportViewer1.RefreshReport();
        }
</script>


// Constructor in Report Class

       // Default Constructor
       public Report1()
        {
              InitializeComponent();
        }

       // Over Loaded Constructor
        public IHEPrescriptionReport(string name)
        {
            InitializeComponent();

            // Assign Value to Report Parameters
            this.ReportParameters["name"].Value = name;

        }

I'll appreciate any help.
