how to dynamic bind data in asp.net

hi guys:
i have a difficulty to dynamic data in web form. the code see below:
public partial class PuchasePrint : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (wrptPuchasePrint.ReportFile == String.Empty)
{
wrptPuchasePrint.ReportFile = Server.MapPath("/PuchasePrint.frx");
wrptPuchasePrint.Prepare();
}
}

protected void wrptPuchasePrint_StartReport(object sender, EventArgs e)
{
FastReport.Report FReport = (sender as FastReport.Web.WebReport).Report;
RegisterData(FReport);
}

private void RegisterData(FastReport.Report FReport)
{
string beginDate = txtBeginDate.Text, endDate = txtEndDate.Text;

DataSet dtPushasePrint = GetDataSet();//ServiceFactory.GetInstance().GetOrderInfoService().GetPuchasePrint(beginDate, endDate);
wrptPuchasePrint.Report.RegisterData(dtPushasePrint, "Table");
//?§?»??????®???¦????°?¦???®?????°?¦????°?¦???®????????????
DataBand band = FReport.FindObject("Data1") as DataBand;
band.DataSource = FReport.GetDataSource("Table");
}

protected void btnQuery_Click(object sender, EventArgs e)
{
FastReport.Data.DataSourceBase dsb = wrptPuchasePrint.Report.GetDataSource("Table");
wrptPuchasePrint.Report.SetParameterValue("@BeginDate";, txtBeginDate.Text);
wrptPuchasePrint.Report.SetParameterValue("@EndDate";, txtEndDate.Text);
wrptPuchasePrint.ReportFile = Server.MapPath("/PuchasePrint.frx");
wrptPuchasePrint.Prepare();

}

private DataSet GetDataSet()
{
string connectionString = @Data Source=***.***.***.***;Initial Catalog=******;Integrated Security=False;Persist Security Info=False;User ID=*****;Password=********; Connect Timeout=300;
DataSet dataSet;
string beginDate = txtBeginDate.Text;
string endDate = txtEndDate.Text;
using (SqlConnection connection =
new SqlConnection(connectionString))
{
SqlDataAdapter adapter = new SqlDataAdapter();
// adapter.TableMappings.Add("Table", "t_Users");
SqlCommand command = new SqlCommand(
string.Format("SELECT FProductQty,FProductSKU,FProductName,FOrderId FROM t_OrderDetail WHERE FOrderId BETWEEN '{0}' and '{1}'", beginDate, endDate),
connection);
command.CommandType = CommandType.Text;
adapter.SelectCommand = command;
dataSet = new DataSet("t_OrderDetail");
adapter.Fill(dataSet);
}
return dataSet;
}
}
