Telerik Reports - Parameter Binding

[James]

Hello Telerik Team,

I'm find it difficult to pass a report parameter value from the client side and access the particular value within the Telerik report class.

cshtml code.

@{
        TypeReportSource typeReportSource = new TypeReportSource() { TypeName = typeof(TestTelerik.Website.Reports.MySales).AssemblyQualifiedName };
        typeReportSource.Parameters.Add("param", "A");
    }

    @(Html.TelerikReporting().ReportViewer()
    .Id("reportViewer1")
    .ServiceUrl(Url.Content("~/api/reports/"))
    .TemplateUrl(Url.Content("~/ReportViewer/templates/telerikReportViewerTemplate-9.1.15.624.html"))
    .ReportSource(typeReportSource)
    .ViewMode(ViewMode.Interactive)
    .ScaleMode(ScaleMode.Specific)
    .Scale(1.0)
    .PersistSession(false)
    .PrintMode(PrintMode.AutoSelect)
    .Deferred()

 

I have defined a method to trigger NeedDataBind event which is as follows.

private void ProductReport_NeedDataSource(object sender, EventArgs e)
{
      var myParam = this.ReportParameters["param"].Value.ToString();
}

 

Also i have defined report parameter as follows. However, this.ReportParameters["param"].Value is always null. Could I know what am I doing wrong in my code.

reportParameter1.Name = "param";
this.ReportParameters.Add(reportParameter1);

Hello James,

The passed parameters values can be obtained in report events through the processing report's Parameters collection e.g. Using Report Events.

I will appreciate it if you elaborate on the reason to access parameters values in code.
