How To: Pass Values to Report Parameters

This topic explains how to update the report parameters with values passed from the custom UI instead of using report viewer's default parameters area. The report and all required parameters for it are packed in a ReportSource object. To update the report source, the setReportSource(rs) method is used.

  1. Add an element that triggers the refresh of the viewer in html page:

    <button (click="onButtonClick(value)">Update parameter value</button>
  2. Declare the variable for the viewer and update the viewer's report source with a new parameter value:

            import { Component, ViewChild } from '@angular/core';
    export class AppComponent {
    @ViewChild('viewer1') viewer;
      onButtonClick(param: string) {
    var rs = {
            report: 'Telerik.Reporting.Examples.CSharp.Invoice, CSharp.ReportLibrary, Version=, Culture=neutral, PublicKeyToken=null',
            parameters: {OrderNumber: param}

    SetReportSource method will automatically reload the report with new parameters into the view.
