Sorry for the inconvenience caused.
Query 1: I was unable to execute the example that you send me, it shows me some compilation errors:
The reported error will occur if the dll’s assemblies are not referenced properly in the sample. You have to refer the dll’s that are installed in the system and the assembly details can be found from the following installed location.
Query 2: I still getting the same issue with the edition of the date field.
We are unable to reproduce the reported issue at our end. After editing the date value on clicking the save button will call Batch Url along with changed value. In server side,modified date value is returned without TimeZone. But in your sample date value is retuned with time zone.
Still facing the issue please get back to us, with following details.
From the shared screenshot, we could see that the date value (yours) is received with timezone. So, please confirm whether are you changing the date value in the client side using any events. If yes, please share the details. Also share the code related to client side events.
Share the video demo of the issue.
If possible reproduce reported issue in the provided sample and revert back to us.
