Datagridview save changes to Database vb.net

Question

Hello i\'ve a databse that i load to Datagridview in vb.net application. it loads fine, however when i try to save the date it doesn\'t work. here is the code

Answer 1

So you must define an InsertCommand for you DataAdapter

Side-note: The line DSet.AcceptChanges() is redundant since the previous line Dadapter.Update will call AcceptChanges implicitely.

You should use using-statement for anything implementing IDisposable like a Connection. That would call Dispose(which closes the connection) implicitely even in case of an exception.

So replace:

con.Open()
Dadapter.Update(DSet, "Table1")
DSet.AcceptChanges()
con.Close()

with

Using con =  New OleDbConnection(myConString)
    con .Open()
    Dadapter.Update(DSet, "Table1")
End Using
