Eventing Timing

[Andrew]

Hello,

I''m experiencing issues with the firing of events in the chart control. I have a function on my windows form that creates the desired chart from values returned from a database. This works fine, my problem comes with printing the chart.

I have a print routine that calls the function that creates the desired chart.

Call InitializeChartData(forum_id, cust_id)

A few lines down I make the call to the print function: pd.Print();

The problem I am having is that a red line I paint on the axis is not printing. Here is the function that draws the line:

Private Sub chartControl1_ChartAreaPaint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles ChartCntrlStrScrd.ChartAreaPaint

Dim chartAreaRect As Rectangle = Me.ChartCntrlStrScrd.GetChartAreaBounds
Dim rangeLength As Double = Me.ChartCntrlStrScrd.PrimaryXAxis.Range.Max - Me.ChartCntrlStrScrd.PrimaryXAxis.Range.Min
If (Me.ChartCntrlStrScrd.PrimaryXAxis.Range.Max > 0) And (Me.ChartCntrlStrScrd.PrimaryXAxis.Range.Min < 0) Then
Dim xposition As Double = chartAreaRect.Width * Me.ChartCntrlStrScrd.PrimaryXAxis.Range.Max / rangeLength
e.Graphics.DrawLine(New Pen(Color.Red), New Point(CInt(xposition), 0), New Point(CInt(xposition), chartAreaRect.Width))

End If

End Sub

How come this is being called after the print function has completed, hence the red line doesn''t appear on my printed chart?

Thanks,

Andrew

Hi Andrew,

The ChartAreaPaint event is not taken into account when the document is printed. We will need to modify the behavior to provide a alternative or invoke this event during the printing and saving to a image.

I have submitted a fix for this issue and it will be available in a build at the earliest.

Thank you for your patience.

Regards,

Davis

Thank you for the explanation, I look forward to the next available build.

Thanks,

Andrew
