Hi Yonghan,

Indeed we must admit that this is a bug introduced in the latest internal build. We have forwarded it to our developers and it will be addressed for the next internal build (scheduled on Monday).

In the meantime, we can suggest you two possible workarounds if you would like to stick with the internal build binaries:

• Besides setting SeriesDefinition.ShowPointMarks to false, set SeriesDefinition.ShowItemLabels / ShowItemToolTips  to false as well -- this will convert the line series to "fast mode" (i.e. it will not generate individual series items and consequently their point marks).
• Alternatively you can set the ShowPointMarks declaration ta bit later in the Silverlight lifecycle and that will ensure it is executed properly:

public partial class MainPage : UserControl
{
    public MainPage()
    {
        InitializeComponent();

        SeriesMapping sm = new SeriesMapping();
        sm.SeriesDefinition = new LineSeriesDefinition();
        sm.ItemMappings.Add(new ItemMapping("YValue", DataPointMember.YValue));

        RadChart1.SeriesMappings.Add(sm);

        RadChart1.ItemsSource = GetData();
        RadChart1.SizeChanged += new SizeChangedEventHandler(RadChart1_SizeChanged);
    }

    private void RadChart1_SizeChanged(object sender, SizeChangedEventArgs e)
    {
        (RadChart1.SeriesMappings[0].SeriesDefinition as LineSeriesDefinition).ShowPointMarks = false;
    }

    private static List<ChartData> GetData()
    {
        var data = new List<ChartData>();
        data.Add(new ChartData() { YValue = 10 });
        data.Add(new ChartData() { YValue = 20 });
        data.Add(new ChartData() { YValue = 5 });
        data.Add(new ChartData() { YValue = 15 });
        return data;
    }
}

public class ChartData
{
    public double YValue
    {
        get;
        set;
    }
}

Sorry for the temporary inconvenience.
