Thank you for contacting Syncfusion support.
We are unable to understand the query from the shared details. Could you please provide us more specific details on the reported error and the Syncfusion control that causes the issue? As you have mentioned “error after the object is saved”, please explain us on what object is saved and what are the Syncfusion controls that you are using at your end. In general ArgumentNullException checks arguments for null and then throws the error explicitly so please check whether the arguments passed are of null value. Based on the shared details and stacktrace ensure whether you have passed the string value that is not null in Regex.Replace () method. Check the following reference here where Regex.Match () raises the ArgumentNullException. http://stackoverflow.com/questions/10838567/match-function-in-regular-expressions-being-null
