Hi,

I saw a similar post already in this forum and there was no clear answer posted. Therefor I want to post an identical problem I focus. I use version 3.5 and just tried it with the lates 2011 version (trial), but still with no luck.

I'm trying to derive my own series from a TeeChart.NET series type and then in my derived class, I add my own custom properties which are known types (like string, int, double, ...). I need the custom series to be serialized to and deserialized from a .TEN file.

This seemed to work ok in a simple test case (as long as I provided a default constructor and a constructor taking a Chart), but in my main project, I can't seem to get it to work. TeeChart.NET would crash when attempting to load my ".TEN" file with the custom series: a system.reflection.TargetInvocationException.... I do exactly the same like in my simple test case, so I assume that my derived class works fine. I also tried with ISerializable, and I know this technique very well, but without success.

I know that it should be better that I can post my main project, but it is rather a big project... I tried already everything but keep on being desperite.
Do you have already a solution for this?
Thank you.

Hello DaVinci,

I recommend you take a look in this thread or in Tutorials, concretely tutorial 19 where explain as you do to Serialize/UnSerialize a Custom Series. If you have done previous suggestion and your problem still appears, you need modified your project example that works fine until the project crash to try to solve the problem.

I hope will helps.

Thanks,
