I'm working with WPF

Thanks a lot Chris, that really helped.

I've been also trying to export it to a PDF file, I almost did it but I still have a little problem as I'm having only a part of my XamDataChart in the PDF file and not the entire Chart.

I've been working on this on my own so maybe you can give me another way to do this.

Thanks again.

Hi slaimi,

You are certainly welcome. It may be possible to export the chart to pdf, but this behavior is not supported yet with our WPF/Silverlight components.

One possible approach that I can think of would include implementing the Documents engine from Windows Forms, (which does support exporting to pdf), wherein a report is created with a report section as its content; this component would then be hosted in WPF, an image of the chart area added to the report section and then exporting the resulting report to pdf; this approach may work in theory.

What is the current approach that you are using? I would be more than happy to take a look at your current implementation and offer my suggestions.

Hello,

I am just checking if you require any further assistance on the matter.

Hello Slaimi,

I have been looking into latest post and it is occurs because the provided approach uses the actual size(height,width) of the XamDataChart. In this scenario the width of the PDF page is not big enough to show the whole chart. If you would like to export the entire chart to the pdf page you can check the actual width of the XamDataChart in the ‘SaveImage’ method like :

if (element != null)

            {

                RenderTargetBitmap bmpSource;

                if (element.ActualHeight < 800)

                {

                     bmpSource =

                        new RenderTargetBitmap(

                            (int)element.ActualWidth,

                            (int)element.ActualHeight, 96, 96,

                            PixelFormats.Pbgra32);

                }

                else

                {

                     bmpSource =

                       new RenderTargetBitmap(

                           (int)element.ActualWidth,

                           (int)element.ActualHeight, 60, 60,

                           PixelFormats.Pbgra32);

                }

                bmpSource.Render(element);

                imgEncoder.Frames.Add(BitmapFrame.Create(bmpSource));

                using (Stream stream = File.Create(fileName))

                {

                    imgEncoder.Save(stream);

                    stream.Close();

                }

            }

I am attaching a modified version of Chris’ sample application(ExportXDChartToPDF119194_Modified.zip).

Please note that this is a custom approach.

Let me know, if you need any further assistance on this matter.

Hi Chris,

I still have the same problem with this approach: when my chart is on full screen, the PDF file contains only a part of the chart and not the entire chart. You can try with your example and modify the width and the height.

I would like to thank you for your precious help.

Scincerely.

Hi Slaimi,

I took a look at the blog post that you mentioned and the approach that Tom describes is exactly what I had in mind.

I have included a modified version of that sample which demonstrates this behavior; to use the approach you would need to also install NetAdvantage for Windows Forms which includes the Documents assemblies that are required; for my sample, I have included only the assemblies necessary that you may not have on your machine.

Please take a look at the attached sample and if you have any further questions regarding this behavior, please let me know.
