  This seems to be caused by the change for fixing https://developer.mescius.com/forums/winforms-edition/applying-theme-to-c1flexgrid-resets-cellstyle-datamap - now “CellStyle.BuildString” tries to serialize a DataMap. But in my sample, the datamap items are not serializable.
  
  This causes a crash with .643 - see attached sample FlexColDataType.zip:

  System.Reflection.TargetInvocationException
    HResult=0x80131604
    Message=Exception has been thrown by the target of an invocation.

    This exception was originally thrown at this call stack:

  Inner Exception 1:
  SerializationException: Type 'FlexColDataType.MyData' in Assembly 'FlexColDataType, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
  

  Making our DataMap data serializable is not really an option…

  My suggestion would be to store the DataMap content in some variable in C1FlexGrid.ThemeChanged and restore if afterwards instead of relying on the style string.

  And my own workaround will be to reset the datamap before applying a theme.

  Hi Wolfgang,

  As per the development team, this issue needs a little more research to determine if it can be completely fixed or not. They have provide an estimate of 2024v1 HF1/HF2 release for the fix.

  Thank you for your patience.

  Thanks, I can confirm that the DataMap is not affected by setting a theme any more, and no crash occurs any longer

  Best regards
