This is how i add
Insert into table (Name, AddDate) values ('" & Name & "', '" & Date.Now & "')"
After adding the record i refresh dgv
("Select * from table")
Form1.DGV.DataSource = SQLDataset1.Tables(0)

sqlcon.Open()
SqlCom = New SqlCommand(addStr, sqlcon)
SqlCom.ExecuteNonQuery()
sqlcon.Close()

sql.resetDGV()
End If

There are easier ways outside in the www. But this is the shortest so....
Public Sub addIt(Name As String) as int
Dim insertedID as int = -1
Try
Dim addStr As String = "Insert into tableName (Name, AddDate) OUTPUT INSERTED.ID values ('" & Name & "', '" & Date.Now & "')"
sqlcon.Open()
SqlCom = New SqlCommand(addStr, sqlcon)
returnValue = Convert.ToInt32(SqlCom.ExecuteScalar())
sqlcon.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
return insertedID
End Sub
If Len(town) >= 3 Then
Dim insertedID as int = sql.addIt(town)
If insertedID = -1 Then return
Msgbox("Added")
sql.resetDGV()
'Select
SelectLastInsertedRow(insertedID)
End If
Public Sub resetDGV()
sqlquery("Select * from tableName")
Form1.dgv.DataSource = SQLDataset.Tables(0)
End Sub
Private Sub SelectLastInsertedRow(id as int)
For Each row as DataGridViewRow in dgv.Rows
'Check if row belongs to the ID
if(row == id) Then
'Select
row.Select = true
End if
End For
End Sub
This code is not tested. But it should work :P
