hi,
i used this command to save data to my database
me.validate()
me.bindingsource.endedit()
me.tableadapter.update(me.dataset.datatable)
On clicking the save button on my winform it brings the error

System.Data.DBConcurrencyException: ConcurrencyViolation: The UpdateCommand affected 0 of the expected 1 records

How do i go about it? thanks

hai,
           try using same datatypes& also check out whether it points to the same fields.....
