Export cartesianchart to RadDocument in code behind

[Auvo]

Hi

I need to create Windows service,which creates the cartesianChart with data and placed it to the radDocument with additional controls (logo, titles, table)

If I add series and other fields (logo, texts,..) first to the visual element like stackpanel, and then creating a RadDcoument from there, it works ok

 

But can I do this without placing chart first to the visual element? If I try to do this, it's throw "The parameter value must be greater than zero.
Parameter name: pixelWidth" error

 

If this can be done, can you provide an example?

 

Regards,

Auvo

Hello Auvo,

I guess you are using the ExportToImage() method to export the chart to a picture and than placing it in the RadDocument. In any case you will need to measure and arrange the control before exporting it to any format. Adding the chart to the visual tree measures and arranges it. However, you can do that manually by calling its Measure() and Arrange(), and also UpdateLayout() methods before you call the export method. Here is an example in code:

chart.Measure(new Size(400, 400));
chart.Arrange(new Rect(new Size(400, 400)));
chart.UpdateLayout();
