Is there an VB.net equivalent for the following C# post? Using CType causes a runtime crash.
private void Button1_Click(object sender, System.EventArgs e)
{
(WebChart1.Chart.Series[0] as Steema.TeeChart.Styles.Shape).Style = Steema.TeeChart.Styles.ShapeStyles.Rectangle;
}

Hello,
It works fine for me here using:
Code: Select all
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
CType(WebChart1.Chart.Series(0), Steema.TeeChart.Styles.Shape).Style = Steema.TeeChart.Styles.ShapeStyles.Rectangle
End Sub

Thanks for the quick reply. I tried that, but the error I'm getting at run time is:
Unable to to cast object of type 'Steema.TeeChart.Styles.Points' to type 'Steema.TeeChart.Styles.Shape'
I'm adding the points like this:
defectPoints(i) = New Steema.TeeChart.Styles.Points(tchart.Chart)

Hi newbie,
What you are doing here is adding point series. If you want to change its pointer style you need to do something like:
Code: Select all
CType(WebChart1.Chart.Series(1), Steema.TeeChart.Styles.Points).Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Circle
