How to Bind to a DataTable

The following example illustrates how to use a DataTable as the source for an ObjectDataSource component. The code below additionally creates a calculated field that can be used in the report definition in the same way as a regular field.

void Form2_Load(object sender, EventArgs e)
    // Creating and configuring the ObjectDataSource component:
    var objectDataSource = new Telerik.Reporting.ObjectDataSource();
    objectDataSource.DataSource = GetData(); // GetData returns a DataTable
    objectDataSource.CalculatedFields.Add(new Telerik.Reporting.CalculatedField("FullName", typeof(string), "=Fields.Name + ' ' + Fields.ProductNumber")); // Adding a sample calculated field.

    // Creating a new report
    var report = new Report1();

    // Assigning the ObjectDataSource component to the DataSource property of the report.
    report.DataSource = objectDataSource;

    // Use the InstanceReportSource to pass the report to the viewer for displaying
    var reportSource = new Telerik.Reporting.InstanceReportSource();
    reportSource.ReportDocument = report;

    // Assigning the report to the report viewer.
    reportViewer1.ReportSource = reportSource;

    // Calling the RefreshReport method in case this is a WinForms application.

static DataTable GetData()
    const string connectionString =
        "Data Source=(local)\\SQLEXPRESS;Initial Catalog=AdventureWorks;Integrated Security=True";

    string selectCommandText =
        "SELECT Name, ProductNumber FROM Production.Product;";

    SqlDataAdapter dataAdapter = new SqlDataAdapter(selectCommandText, connectionString);
    DataTable dataTable = new DataTable();


    return dataTable;
