Hello MVUser6,

I am afraid that this problems is not only of TeeChart, so after have been doing some test, we have found that the problem isn't only of TeeChart functions, it depends of GDIPlusCanvas, so it isn't call the TChart canvas, because is calling other canvas. To solve the problem of export must be modified the GDIPlusCanvas, because GDIPlusCanvas supports this type of export,therefore, we can not solve the problem with TeeChart, if previously isn't solved the problem with export to xaml in GDIPlusCanvas. On the other hand, as this thread is related by this other. I have increased the severity of wish-list item (TW16016325) to try to fix it for upcoming maintenance release of TeeChartFor.Net.

Thanks,

hi,

i tried to make some manipulations and i succeed to export it without your export function.
however, i still have problems and i don't want this workaround to stay permanent.
here is the code:

DrawingVisual dv = new DrawingVisual();
DrawingImage di = new DrawingImage();
System.Windows.Rect r = TChartControl.Chart.ChartBounds;
DrawingContext dc = dv.RenderOpen();
TChartControl.Chart.Draw(dc);
dc.Close();
di.Drawing = dv.Drawing;


and afterwards exporting the DrawingImage to XAML with XAMLWriter.
i hope it can help you solve the bug or get ideas.

please fix it as soon as you can.

Hi,
in addition,
I was trying to use FillRegion and receveid NotImplementedException.

You have suggested that we use the example in the following link:
http://social.msdn.microsoft.com/Forums ... 4a72b9042/

[reference: http://www.teechart.net/support/viewtop ... =4&t=13614]

The region is now being painted however not appearing when using the XAML export.

Please advise.

Hello MVUser6,

I am glad, that you can solve your problem using a native method of WPF, to export it as XAML. .

About Export text as I have informed,in previous thread, I have increased the severity of bug number [TW16016325] to try solve the problems with TextOut, so it works in our and your end.

About FillRegion, is normal as you implement a custom FillRegion as I have recommended you, the exportation of TeeChartWPF doesn't export the FillRegion you implement, because isn't a method of TeeChart. Therefore, if you want export a chart where you use a custom FillRegion, you need use the native methods of WPF to export it. On the other hand, if you want export it as TeeChart, would be very grateful if you can explain exactly that you want achieve draw with FillRegion, because we can try to find a solution with TeeChart methods(rectangle(), elipse(),etc),so, you can export it in a correct way using TeeChart.

Thanks,

Hi,
The bug is about drawtext and not about textout. with textout we don't have a problem.

[MVUser6]

hi,

in addition - my way of export doesn't export the workaround also.
i will try to draw our shapes by myself but solving the FillRegion issue is still required by us.

Hello MVUser6,

The bug is about drawtext and not about textout. with textout we don't have a problem.

DrawText of GDIPlusCanvas as I have explained, method DrawText, internally, is calling other canvas that isn't the TChart Canvas and for this reason the text doesn't export correctly in xaml TeeChart.

So, we will try implement the feature request number [TW16016325] because TextOut supports TextOptions.TextRenderingMode so that fonts look better and you can use the TextOut method as alternative of DrawText method to achieve the same results, thus you can use export xaml methods of TeeChart without problems.

i will try to draw our shapes by myself but solving the FillRegion issue is still required by us.

I inform you that we have already implemented the FillRegion of WPF feature request for next maintenance releases of TeeChartFor.Net. Feature request number is [TW16016406].

Thanks,
