Hi,

 On a bare bones page with just a simple XamChart, I'm running into the following problem:

If I create the chart in markup, the mousedown-hittest sequence returns HitTestArgs with the clicked DataPoint.

However, when I create a series of DataPoints in code,  the SelectedObject in the HitTestArgs is always null.

This XAML produces correct result for MouseDown/HitTest:

            <igCA:Series ChartType="Bar" Label="Series 1">
          <igCA:Series.DataPoints>
                        <igCA:DataPoint Label="Point 1" Value="2" />
                        <igCA:DataPoint Label="Point 2" Value="1" />
                        <igCA:DataPoint Label="Point 3" Value="3" />
                    </igCA:Series.DataPoints>
                </igCA:Series>
            </igCA:XamChart.Series>

But when I comment out the DataPoints section and replace it with this code:

            Series sr = chart.Series[0];

            for (int i = 0; i < 4; i++)
            {
                DataPoint dp = new DataPoint();
                dp.Value = i * 3;
                sr.DataPoints.Add(dp);
            }

The Graph looks identical, but HitTestArgs SelectedObject is always null.

 Ideas?
