Parameter values are not shown for SSRS rdl report viewed in ReportViewer

Am new to ReportViewer and trying to render a rdl in reportviewer to analyize if we want to go ahead with the product.

Am using SSRS rdl report with parameter values got from a query, which when ran on report builder works fine but when the report is viewed in ReportViewer the parameter doesn't show any values and is greyedout, Do I need to define in code the values for the parameter which already exists in the report? If so how do I do that?

I would rather show reports from SSRS report server but would like to see how this works as well. For this I opened anotehr thread.

Thank you.

Hi Dheeraj, 

We can pass the parameter using the “report-loaded” event in ASP.NET Core application as shown in below code snippet. 
<div style=" align-items:center; height:525px;width: 100%;"> 
    <ej-report-viewer id="reportviewer1" report-service-url="../Home" report-loaded="onReportLoaded" report-path="/ReportsTemplate/Sales Order Detail.rdl" processing-mode="Remote" /> 
<script type="text/javascript"> 
    function onReportLoaded(sender) { 
        var reportObj = $('#reportviewer1').data("ejReportViewer"); 
        reportObj.model.parameters = [{ 
            name: 'SalesOrderNumber', 
            labels: ['SO50752'], 
            values: ['SO50752'], 
            nullable: false 

We have prepared the simple sample for your reference and it can be downloaded from below location. 

Please let us know if you need any clarification.
