RDLC Report Dot Net Core MVC

Step 1: Install the necessary packages

Install the Microsoft.ReportingServices.ReportViewerControl.WebForms package from NuGet. This package provides the Report Viewer control for ASP.NET Core.

Step 2: Create a new RDLC report

Right-click on your project, go to Add -> New Item.
Select "Report" from the Visual C# Items -> Reporting category.
Name the report and click "Add".
Design your report using the RDLC designer.

Step 3: Configure Report Viewer in the View

In your MVC View where you want to display the report, add the following code to include the Report Viewer control:

@{
    ViewData["Title"] = "Report View";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

Report View




@section scripts{
    
    
}

Step 4: Configure the controller action to render the report

In your controller, add an action method to retrieve the data and render the report:

using Microsoft.Reporting.WebForms;

public class ReportController : Controller
{
    public IActionResult Index()
    {
        // Create a new LocalReport object
        LocalReport localReport = new LocalReport();

        // Specify the path to the RDLC report file
        string reportPath = Path.Combine(Server.MapPath("~/Reports"), "YourReport.rdlc");
        localReport.ReportPath = reportPath;

        // Set the data source for the report (e.g., retrieve data from a database)
        // ...

        // Set the report parameters if needed
        // ...

        // Render the report into a byte array
        byte[] reportBytes = localReport.Render("PDF");

        // Return the report as a FileResult
        return File(reportBytes, "application/pdf", "Report.pdf");
    }
}

Make sure to replace "YourReport.rdlc" with the actual filename of your RDLC report.

Step 5: Configure the route to the controller action

In your Startup.cs file, add a route to map the URL to the controller action:

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "report",
        pattern: "report",
        defaults: new { controller = "Report", action = "Index" });
});

With these steps, you should be able to create and display an RDLC report in ASP.NET Core MVC 5 using the Report Viewer control.
