Set Parameters Programmatically to Report
You can add collection of report parameters programmatically using the ReportViewerModel’s Parameters property that is the list type of ReportParameter class. The ReportParameter contains Name, Values, Labels, and Nullable properties to specify name, values and labels of report parameter.
Use the following code to set parameters.
C#
public class ReportViewerController : Controller
{
private ReportViewerModel GetInvoiceModel()
{
//Model data class for report viewer
ReportViewerModel reportModel = new ReportViewerModel();
//Set the ReportPath of the Report
reportModel.ReportPath = HttpContext.Server.MapPath("~/App_Data/InvoiceTemplate.rdl");
List<ReportParameter> parameters = new List<ReportParameter>();
ReportParameter parameter = new ReportParameter();
parameter.Name = "InvoiceID";
parameter.Labels.Add("10250");
parameter.Values.Add("10250");
//Add parameter
parameters.Add(parameter);
//Set the parameter collection
reportModel.Parameters = parameters;
return reportModel;
}
public ActionResult Index()
{
//Assign the ReportViewerModel to ViewData for ReportViewer Control
ViewData["ReportModel"] = this.GetInvoiceModel();
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(ReportViewerParams param)
{
//Process the report request from client and send the action result
return new ReportViewerHtmlActionResult(this.GetInvoiceModel(), param);
}
}
Use the following code to set parameters for Sub Report.
C#
public class ReportViewerController : Controller
{
private ReportViewerModel GetReportModel ()
{
//Model data class for report viewer
ReportViewerModel reportModel = new ReportViewerModel();
//Set the ReportPath of the Report
reportModel.ReportPath = HttpContext.Server.MapPath("~/App_Data/SubReport.rdlc");
//Set the ProcessingMode of the Report
reportModel.ProcessingMode = ProcessingMode.Local;
//Hook event for SubReport Model
reportModel.SubReport += model_subReport;
return reportModel;
}
private void model_subReport(object sender, SubreportProcessingEventArgs e)
{
//Set the parameter collection
e.Parameters = new ReportParameterInfoCollection();
ReportParameterInfo parameter = new ReportParameterInfo();
parameter.Name = "InvoiceID";
parameter.Labels.Add("10250");
parameter.Values.Add("10250");
//Add parameter
e.Parameters.Add(parameter);
}
public ActionResult Index()
{
//Assign the ReportViewerModel to ViewData for ReportViewer Control
ViewData["ReportModel"] = this. GetReportModel();
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(ReportViewerParams param)
{
//Process the report request from client and send the action result
return new ReportViewerHtmlActionResult(this. GetReportModel (), param);
}
}
