Hello,I our application we are using the NetAdvantage WinForms v.2008vol3.If we update chart with 10 data points, each 5 seconds during 1 hour the chart crashes(the red cross lines are displayed in plot)Operating System: Windows 8.1Here is stack trace of the error:
System.ArgumentException: Parameter is not valid.

Do you have any idea about what may happens here?Thanks,Vasyl
Hello Vasyl,
Thank you for contacting Infragistics.
Could you provide either a sample project which reproduces the issue or detailed steps I can follow in order to create my own project to try to reproduce the issue?
Hello,We use complicated chart, but the basic approach is that we add some data points periodically.I have attached code of simple project.Thanks,Vasyl
Thank you for providing the code.
I looked at it and it seems you're trying to modify the chart from a non-UI thread. Instead of directly modifying the chart from the non-UI thread, you should create a method that adds the item to the chart and invoke that method from the UI thread during each loop iteration.
Hello,Thanks for your reply.But why this happens only when I update chart for a while(when there are a lot of points) and does not happen each time, on each loop?Vasyl
Vasyl,
Do you have any further questions about this?
Thank you for your response.
Modifying a UI control from a non-UI thread results in "undefined behavior." This means that it may work or it may not work, but it is still not recommended. The following page on MSDN provides more information, specifically in the "Thread Safety" section.
