C#, ReportViewer: How to make Report Path a URL parameter

Question

I am working on a solution that uses Report Viewer to access SSRS reports in our server. Currently the server URL and the repot path, are values stored in the Web.config file.

Web.config  

    <add key="ReportServerUrl" value="https://sqlssrs/reportserver"/>
    <add key="ReportPath" value="/group/type/report-name"/>

Then these values are mapped in the ReportViewer.aspx.cs code behind.

ReportViewer.aspx.cs

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            try
            {

                // Add the Reporting Server URL  
                rvSiteMapping.ServerReport.ReportServerUrl = new Uri(ConfigurationManager.AppSettings["ReportServerUrl"].ToString());

                //Add the Report Path
                rvSiteMapping.ServerReport.ReportPath = ConfigurationManager.AppSettings["ReportPath"].ToString();

                rvSiteMapping.ServerReport.Refresh();
            }
            catch (Exception)
            {

            }
        }
    }

I was asked to try to make a change that will allows us to pass the Report Path value, as a query string parameter.

I am not sure how to accomplish this task. I tried to do the following.

 rvSiteMapping.ServerReport.ReportServerUrl = new Uri("http://sqlssrs/reportserver?pReportPath=/group/type/report-name");

 rvSiteMapping.ServerReport.ReportPath= HttpUtility.ParseQueryString(rvSiteMapping.ServerReport.ReportServerUrl).Get("pReportPath");

That code does not work. It gives me an error that reads.

Error   CS1503  Argument 1: cannot convert from 'System.Uri' to 'string'

Would it be possible to get some instruction on how to be able to accomplish this task? I am running the report within Visual Studio 2015, I am thinking I also need to set the URL in the project configuration, but I am not sure about that either.

I appreciate any direction on how to program this, any articles, examples, whatever can aid me to complete this task.

Thank you for sharing your experience.

You can use Request.QueryString["pReportPath"] to retrieve the query value.

Try:

// Add the Reporting Server URL  
rvSiteMapping.ServerReport.ReportServerUrl = new Uri(ConfigurationManager.AppSettings["ReportServerUrl"].ToString());

//Add the Report Path
rvSiteMapping.ServerReport.ReportPath = Request.QueryString["pReportPath"];

Then navigate your browser to ReportViewer.aspx?pReportPath=/group/type/report-name
