How to bind datatable to reportviewer runtime

Question

I want to do a bind datatable to reportviewer with the code below. I don't see the results appear in the reportviewer, what the lack of script below?

// create dataset
DataSet ds = new DataSet("myDataset");

// create datatable
DataTable dt = new DataTable("myDatatable");

// add columns
dt.Columns.Add("column1", typeof(string));
dt.Columns.Add("column2", typeof(string));
dt.Columns.Add("column3", typeof(string));

// insert data rows
dt.Rows.Add("row1-col1", "row1-col2", "row1-col3");
dt.Rows.Add("row2-col1", "row2-col2", "row2-col3");

// add datatable to dataset 
ds.Tables.Add(dt);

// bind datatable to report viewer
this.reportViewer.Reset();
this.reportViewer.ProcessingMode = ProcessingMode.Local;
this.reportViewer.LocalReport.ReportEmbeddedResource = "Test.Report1.rdlc";
this.reportViewer.LocalReport.DataSources.Clear();
this.reportViewer.LocalReport.DataSources.Add(new ReportDataSource(dt.TableName, dt));
this.reportViewer.RefreshReport();

I found the answer how to bind datatable to reportviewer, I will shared here may be useful for others.

1. Add to form clsTables class, Report1.rdlc file, reportViewer1.
2. Then Click on the upper right corner of the reportViewer1, set choose report to Test.Report1.rdlc.
3. On Report1.rdlc
   • Click New,
   • Add dataset name: dsBody Data source: Test Available dataset: clsTables
   • Click Ok
   • Right click on Report1.rdlc select Insert Table, drag dsBody element(Column0, Colum1, Column2) to Report1.rdlc table.

Namespace Test{
    public class clsTables {
        // constructor
        public clsTables(string col0, string col1, string col2) {
            this.Column0= col0;
            this.Column1= col1;
            this.Column2= col2;
        }

       // properties
       public string Column0{ get; set; }
       public string Column1{ get; set; }
       public string Column2{ get; set; }
    }
}

namespace Test{
    public class clsMain{
        public void BindToRepprtViewer() {        
            // create dataset
            DataSet ds = new DataSet("myDataset");

            // create datatable
            DataTable dt = new DataTable("myDatatable");

            // add columns
            dt.Columns.Add("column1", typeof(string));
            dt.Columns.Add("column2", typeof(string));
            dt.Columns.Add("column3", typeof(string));

            // insert data rows
            dt.Rows.Add("row1-col1", "row1-col2", "row1-col3");
            dt.Rows.Add("row2-col1", "row2-col2", "row2-col3");

            // add datatable to dataset 
            ds.Tables.Add(dt);

            // save rows to rowList 
            List<clsTables> rowList = new List<clsTables>();
            rowList .Clear();
            foreach (DataRow row in dt.Rows) {
                rList.Add(new clsTables(Convert.ToInt32(row.ItemArray[0]), row.ItemArray[1].ToString(), row.ItemArray[2].ToString()));
            }

            // binding rowList to bs
            BindingSource bs = new BindingSource();
            bs.DataSource = rowList;

            // binding bs to rds
            ReportDataSource rds = new ReportDataSource();
            rds.Name = "dsBody";
            rds.Value = bs;

            // binding rds to report viewer
            reportViewer1.Reset();
            reportViewer1.LocalReport.ReportEmbeddedResource =  "Test.Report1.rdlc";
            reportViewer1.LocalReport.DataSources.Clear();
            reportViewer1.LocalReport.DataSources.Add(rds);
            reportViewer1.RefreshReport();
        }
    }
}
