Why does cut operation throw an exception on the number datatype such as integer cells?


When any selected cell has the datatype as an integer on cut operation, it throws an InvalidOperationException was unhandled, Rollback without BeginTrans exception.

When the integer datatype is null during the cut operation and when the datatype does not accept the null values that exception is thrown. You can avoid the exception by setting the nullable datatype to the cells. For example, when you are use int datatype, you need to change it to int?
