Since updating from 3.6 to 3.7.10418.12160 I keep getting ArgumentOutOfRangeException(s) when using xceed datagrids. Code always worked since version 3.2, until now.

 Error detail :

System.ArgumentOutOfRangeException :The specified start position is outside the range of the Generator content.

Hi Krijn,

Could you send us a small test project that reproduces the issue? Please send it to support@xceed.com and include a link to this forum thread for reference. We would then be able to confirm this as a bug and submit a fix request to the development team. Thank you.

Hi

 I have sent you a sample application. Please notify me if you did not receive it.

This was continued through email support. But for others looking in this thread for an answer, the issue is fixed and will be included in the next release that should be coming out in 2 weeks.
