What I am doing-
- Importing 406 rows into 5 sql tables from excel sheet.
- After import, I am manually saving data one by one into each of the 5 tables on button click event and displaying on datagridview..
- After saving each record, I am refreshing datagridview.
My problem -
- Records are getting saved properly, but datagridview shows only 408 records, where actual no. of records are 412.
- When viewed from server explorer also, only 408 records are shown.
- But table properties show that there are 412 rows.
- This problem is with only first table.
