Generate pdf using rdlc c#

In this article I will demonstrate you how to create rdlc report in

Microsoft made it very simple to generate PDF by using the “Microsoft.ReportViewer.WebForms”
Take the reference of Microsoft.ReportViewer.WebForms to work with RDLC. It will appear in your reference folder like below;


Now create the Dataset which you want to link with RDLC file, I have create the dataset for Employee class which is having Name, Salary, EmployeeID and Designation.

Now How to Create the Dataset?

Click on the Solution Explorer à Add New Items you will get the Below Window; Give the Name to Dataset and click on the Add.

Now you will get the XSD file in your solution folder like it for Dataset;


Open XSD and create the datatable that you desire for like below process;


In our solution I created the Dataset like below;

Now Create RDLC file in application on which above datatable will render and generate the PDF file.

Add RDLC file and Drag the List and bind the Dataset with the List. Now it will appear the Screen like Below.

Now need to work with the code in C# to generate the PDF in this RDLC file and link to it.
Create the class which will give the List of Employee details that we are going to display in RDLC pdf file;

  public static List<Employee> GetAllEmployees()
            Employee employee1 = new Employee { EName = "BOB", EmployeeID = "E001", EDesignation = "SW", ESalary = 5000 };
            Employee employee2 = new Employee { EName = "Eric", EmployeeID = "E002", EDesignation = "Manager", ESalary = 8000 };
            Employee employee3 = new Employee { EName = "Danny", EmployeeID = "E003", EDesignation = "SSW", ESalary = 6000 };
            return new List<Employee> { employee1, employee2, employee3 };


We will just call this above method to generate the PRF of list of Employee records;

protected void Page_Load(object sender, EventArgs e)


            Warning[] warnings;
        string[] streamIds;
        string mimeType = string.Empty;
        string encoding = string.Empty; //enter code here`
        string extension = string.Empty;

            ReportViewer viewer = new ReportViewer();
            viewer.LocalReport.ReportPath = "Report1.rdlc"; //This is your rdlc name.
          //  viewer.LocalReport.SetParameters(param);
            ReportDataSource rds = new ReportDataSource();
            rds.Name = "DataSet1";//This refers to the dataset name in the RDLC file
            rds.Value = EmployeeRepository.GetAllEmployees();


            byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
            // byte[] bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
            // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.         
            // System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Buffer = true;
            Response.ContentType = mimeType;
            Response.AddHeader("content-disposition", "attachment; filename= filename" + "." + extension);
            Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file 
            Response.Flush(); // send it to the client to download 



On above code I call the generate PDF using RDLC method into Page Load only; Once you run the Programe you will get the PDF file Directly;
So lets see the output. Its plain PDF but you can change the Font, Color, background color as you need.
