Load RDLC Report Using Report Viewer Programmatically

This tutorial will guide you on how to programmatically load the RDLC Report into Report Viewer Control.

I search the internet on how to do this but I can’t find one. There are answers in some forum site but the solution is not clear and don’t have a sample source code.

In my previous tutorial I discuss the solution for the error “The definition of the report 'Main Report' is invalid”. This time let’s talk about on how we can load the RDLC report programmatically using its own DataSet.

The source code I implemented here is very simple but it’s the best solution. Unlike with other samples on the internet, they use a lot of code to do a very simple task.

Here’s a sample of the code to display the RDLC Report programmatically.

  1. Private Sub frmReport_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
  2.     Dim rptDataSource As ReportDataSource
  3.  
  4.     Try
  5.         With Me.ReportViewer1.LocalReport
  6.             .ReportPath = "Reports\" & strReport & ".rdlc"
  7.             .DataSources.Clear()
  8.         End With
  9.  
  10.         Select strReport
  11.             Case "Employees"
  12.                 Dim ds As New Load_RDLC_Report_Programmatically.EmployeesDataSet
  13.                 Dim da As New Load_RDLC_Report_Programmatically.EmployeesDataSetTableAdapters.EmployeesTableAdapter
  14.  
  15.                 da.Fill(ds.Employees)
  16.  
  17.                 ' Use the same name as defined in the report Data Source Definition
  18.                 rptDataSource = New ReportDataSource("EmployeesDataSet", ds.Tables("Employees"))
  19.             Case "Customers"
  20.                 Dim ds As New Load_RDLC_Report_Programmatically.CustomersDataSet
  21.                 Dim da As New Load_RDLC_Report_Programmatically.CustomersDataSetTableAdapters.CustomersTableAdapter
  22.  
  23.                 da.Fill(ds.Customers)
  24.  
  25.                 ' Use the same name as defined in the report Data Source Definition
  26.                 rptDataSource = New ReportDataSource("CustomersDataSet", ds.Tables("Customers"))
  27.         End Select
  28.  
  29.         Me.ReportViewer1.LocalReport.DataSources.Add(rptDataSource)
  30.  
  31.         Me.ReportViewer1.SetDisplayMode(Microsoft.Reporting.WinForms.DisplayMode.PrintLayout)
  32.     Catch ex As Exception
  33.         MessageBox.Show(ex.Message, My.Application.Info.Title, MessageBoxButtons.OK, MessageBoxIcon.Error)
  34.     End Try
  35. End Sub

Thank you very much. This is a work around I needed for working in asp.net RDLC. It was easy to convert to C# asp.net web page.

Very useful! I've used in c# like this, with an store procedura that get the data, and loaded as a dataset.
  1. //property
  2. public string report;
  3.  
  4.         private void Form1_Load(object sender, EventArgs e)
  5.         {
  6.             var ds = new ImpresosDataSet();
  7.             var reportDataSource = new ReportDataSource { Name = "ReportDataSet" };
  8.             const string rut = "Reporting.Reports.";
  9.  
  10.             switch (report)
  11.             {
  12.                 case "CustomerList":
  13.                     var da = new CustomerListTableAdapter();
  14.                     da.Fill(ds.CustomerList);
  15.                     reportDataSource.Value = da.GetData();
  16.                     break;
  17.                 //default:
  18.             }
  19.  
  20.             reportViewer1.LocalReport.ReportEmbeddedResource = rut + report + ".rdlc";
  21.             reportViewer1.LocalReport.DataSources.Clear();
  22.             reportViewer1.LocalReport.DataSources.Add(reportDataSource);
  23.             reportViewer1.RefreshReport();
  24.         }

Hi!

I'm developing a Windows form Application (c#) using vs2010 I have created the .rdlc report and under report data I gave the parameters for each field. then in the form I gave the following code for a button click even of a button named " view report" where the user gives the primary key value to display the relevant report.
but when I run the application and after clicking that button an exception occurs saying
Microsoft.Reporting.WinForms.LocalProcessingException was unhandled
Message=An error occurred during local report processing.
here's the code I gave

private void button1_Click(object sender, EventArgs e)
{
SqlConnection myconnection1 = new SqlConnection("user=sa;" + "password=123;" + "server=USER-PC\\SQLEXPRESS;" + "Trusted_Connection=Yes;" + "database=Hematology;" + "Connection timeout=30;");
myconnection1.Open();
SqlCommand report = new SqlCommand("Select * FROM Patient p, BMarrow b WHERE p.BHT=b.BHT AND p.BHT= '" + textBox1.Text + "';", myconnection1);
SqlDataReader reader2 = report.ExecuteReader();
if (reader2 != null)
{
if (reader2.Read())
{

//this form has reportviewer 1 and report1.rdlc is the report viewd in that report viewer
/*I have created 3 datasets under report data and dataset1 stands for the 'Patient' table and datase2
stands for the 'BMarrow table' from those two daasets I have dragged and dropped the attributes
into the text boxes in report1.rdlc*/
ReportParameterCollection reportParameters2 = new ReportParameterCollection();
reportParameters2.Add(new ReportParameter("Name", reader2.GetValue(0).ToString()));
reportParameters2.Add(new ReportParameter("Age", reader2.GetValue(1).ToString()));
reportParameters2.Add(new ReportParameter("Sex", reader2.GetValue(2).ToString()));
reportParameters2.Add(new ReportParameter("Ward", reader2.GetValue(3).ToString()));
reportParameters2.Add(new ReportParameter("BHT", reader2.GetValue(4).ToString()));
reportParameters2.Add(new ReportParameter("Indication", reader2.GetValue(5).ToString()));
reportParameters2.Add(new ReportParameter("BM", reader2.GetValue(6).ToString()));
reportParameters2.Add(new ReportParameter("Difficulty", reader2.GetValue(7).ToString()));
reportParameters2.Add(new ReportParameter("SiteOfAspiration", reader2.GetValue(8).ToString()));
reportParameters2.Add(new ReportParameter("Cellularity", reader2.GetValue(9).ToString()));
reportParameters2.Add(new ReportParameter("Erythropoiesis", reader2.GetValue(10).ToString()));
reportParameters2.Add(new ReportParameter("Granulopoiesis", reader2.GetValue(11).ToString()));
reportParameters2.Add(new ReportParameter("Megakaryocytes", reader2.GetValue(12).ToString()));
reportParameters2.Add(new ReportParameter("Abnormal", reader2.GetValue(13).ToString()));
reportParameters2.Add(new ReportParameter("SpecialStains", reader2.GetValue(14).ToString()));
reportParameters2.Add(new ReportParameter("Lymphocytes", reader2.GetValue(15).ToString()));
reportParameters2.Add(new ReportParameter("Conclusion", reader2.GetValue(16).ToString()));
reportParameters2.Add(new ReportParameter("Date", reader2.GetValue(17).ToString()));

this.reportViewer1.LocalReport.SetParameters(reportParameters2);

}

}

what is wrong with this??? I can't understand :( I'm new to this I tried searching the internet but didn't find a solution
