    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:
    Object reference not set to an instance of an object.
