Hello,
Hope all is well.
Check if you have the same version of the C1WebChart and C1Chart dll in your application bin directory. Remove them from GAC if any. If this does not solve the purpose then please attach a small sample replicating this issue.
Thanks,

Thanks Steve for the reply.
i am using c1.web.c1webchart.2.dll of version 2.0.20082.18078 and c1.win.c1webchart.2.dll of version 2.0.20082.18078 in my project. both the versions are same.
i have put the c1chart inside update panel in order to prevent postback. is this creating any problem for me? Please reply.
Thanks and Regards,
Jayanth Nadig
Steve,
If i remove the c1chart from the update panel the application will work perfectly. if i include c1chart in update panel then the error appears inside script manager saying 'c1wc_C1WebChart' is undefined and 'c1cb_createcontext' is undefined.
Please help me.
Any solution for this problem?
Are C1 controls not compatible with Ajax.Net?
Regards
Stefan

Hello Stefan,
I am having no problems using the ComponentOne controls within an UpdatePanel. Please see the attached sample. If this does not help, could you please provide a small, simplified sample that reproduces you problem? Thanks and I hope this helps!

Hi Raleigh,
this only happens, if the UpdatePanel isn't Visible at initial Page Request. See the sample in my previous post.I've found a workaround, I placed a WebChart with size 0;0 outside the UpdatePanels. Ugly, but it works.
I am still unable to reproduce this problem. I am attaching another sample for you to take a look at. Please feel free to make any corrections to this sample to make it reproduce the issue. I look forward to your reply.
Hi I have the same problem.
Even with your example (as a side note, the web config of your example isn't correct either. It references C1.Win.C1Chart.2.dll which you didn't include in the project - and thus with the wrong version number of the dll.)
I'm using version 2.0.20093.19342 of C1Chart and C1WebChart.
We are experiencing the same problem for quite a while throughout a range of different versions of C1. We are currently using IE8.
Can someone have a look into it or is there a solution by now? On your example: Pressing the Button results in the two js errors mentioned above: screenshot for the second is attached
