Telerik Reporting | Set Report Parameter Via Query String

Question

Problem: I am trying to pass a Report Parameter value from the query string on the page to my report that already has the parameter defined. I just can't seem to get the value passed all the way to the report.

        Telerik.Reporting.Report report = new MyCustomReportLibrary.TelerikReport();
        report.ReportParameters["parameterName"].Value = Request.QueryString["Id"];

        ReportViewer.Report = report;

This syntax above is fine but when the variable "report" is created by the TelerikReport() constructor it doesn't have a value for the parameter yet and when I set it after the fact it doesn't seem to matter. Even if I try to call a ReportViewer.RefreshReport().

Places I have looked:

• Telerik Documentation on using Telerik Reporting in Web Apps
• Telerik Community Support
• I also submitted a telerik support ticket but tomorrow is Bulgarian Independence day.

Thanks for the help,

Chris

Answer 1

I was able to get it to work by altering the Contructor for MyCustomReportLibrary.TelerikReport. Hope this helps anyone looking for the answer.

Much like this example Telerik Forums | Pass Report parameters from Rad window to a telerik report

Telerik Report Code (TelerikReport.cs)

    public TelerikReport(int Id)
    {
        //
        // Required for telerik Reporting designer support
        //
        InitializeComponent();

        this.ReportParameters["parameterName"].Value = Id;
    } 

ASP.Net Page Code (ReportViewerPage.cs)

    protected void Page_Load(object sender, EventArgs e)
    {
        Report raReport = new TelerikReport(Request.QueryString["Id"] as int);
        ReportViewer1.Report = raReport;
    }
