hi
How can use ScrollMode when chart data bounded programmatically?
my c# code is look like this:

protected void Page_Load(object sender, EventArgs e)
{
    ConnectionStringSettings connectionString = ConfigurationManager.ConnectionStrings["database"];
    SqlConnection connection = new SqlConnection(connectionString.ConnectionString);
    SqlCommand command = new SqlCommand("selectDetails", connection);
    command.CommandType = CommandType.StoredProcedure;
    SqlDataAdapter dataAdapter = new SqlDataAdapter();
    dataAdapter.SelectCommand = command;
    DataSet dataSet = new DataSet();
    dataAdapter.Fill(dataSet, "info");
    chart.ClientSettings.EnableZoom = true;
    chart.ClientSettings.ScrollMode = Telerik.Web.UI.ChartClientScrollMode.XOnly;
    chart.DataSource = dataSet.Tables["info"];
    chart.DataBind();
}

but I get this exception:
