changetype changes selectedindex in ChartListBox

Hi,
I created a series, and changed its series type at runtime, but the selectindex of ChartListBox is lost and reset to -1 afterwards. Is this a known bug? or supposed to be?
Code: Select all
chart.Series.Clear();
Steema.TeeChart.Styles.Series s0=chart.Series.Add(typeof(Steema.TeeChart.Styles.Points));
Steema.TeeChart.Styles.Series.ChangeType(ref s0,
typeof(Steema.TeeChart.Styles.Line));
Assert.AreEqual(ChartListBox.SelectedIndex,0);
Best regards
Fang

Hi Fang,
It works fine here using the code above and latest available version.
Code: Select all
private void chartListBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
chart.Header.Text=this.chartListBox1.SelectedIndex.ToString();
}
Which TeeChart version are you using? If you are still having problems please send us an example we can run "as-is" to reproduce the problem here.
You can post your examples at [url]news://

I used the same version in the download section.
But I created the chart and chartlistbox in the library class(not visually), not sure if it's related.

Hi Fang,
Thank you very much for the example project.
the code above (with
m_ChartListBox.FillSeries(null)) works:
Code: Select all
public void TEST_HERE()
{
Steema.TeeChart.Styles.Series s=
this.Series.Add(typeof(Steema.TeeChart.Styles.Points));
int i=m_ChartListBox.SelectedIndex; // should be zero
Steema.TeeChart.Styles.Series.ChangeType(ref s,
typeof(Steema.TeeChart.Styles.Line));
m_ChartListBox.FillSeries(null);
int j=m_ChartListBox.SelectedIndex; // should be zero
}
