In case you are adding row by row, then clear the rows of datagridview first in the function How we can access the entry’s in another system using LAN while running software in both systems. i want to add, delete, update in my C# forms through DLL… I have 5 tables and one datagridview , which display the information from 5 different tables, now user is allowed add/update/delete opration in the grid with new information.
How to write the connection string to that in windows application(C#). adding , deleting , updating textboxes is very simple if we write codes on buttons. user can add or update or delete the datagridview row.
