The infragistics website contains an example that shows how to hide a series. While Hiding a series is easy, i want to dynamically add Series based on the values of a Webdropdown i parse into a list.

The following code is used to add a series, based on a date range and a multiselect dropdown:

DataTable datatable = new DataTable();
int i;
DataTable dt = new DataTable("TestTabel");
dt.Columns.Add("Machine", typeof(string));

for (i = 0; i < WebDropDown1.SelectedItems.Count; i++)
{
dt.Rows.Add(WebDropDown1.SelectedItems[i].Value.ToString());
}
string cs = string.Empty;

cs = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;

SqlConnection con = new SqlConnection(cs);

con.Open();
SqlCommand cmd = new SqlCommand("FPYMaschineTabelle", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter tblvaluetype = cmd.Parameters.AddWithValue("@List", dt); //Passing table value parameter
SqlParameter Beginn = cmd.Parameters.AddWithValue("Beginn", WebDatePicker1.Value);
SqlParameter Ende = cmd.Parameters.AddWithValue("End", WebDatePicker2.Value);
tblvaluetype.SqlDbType = SqlDbType.Structured; // This is used to tell ADO.NET we are passing Table value Parameter

SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DataTable SeriesTable = ds.Tables[0];

NumericSeries Series = new NumericSeries();
Series.Data.DataSource = SeriesTable;
Series.Data.LabelColumn = "Date";
Series.Data.ValueColumn = "FPY";
Series.DataBind();
UltraChart1.Series.Add(Series);

UltraChart1.Data.DataBind();
UltraChart1.Axis.X.Extent = 110;

con.Close();

How can I add a new series with the value column as the string for the stringlist and label column as date ?
