Question

I have a program that inserts data in access database and the user can view the newly added items in a data grid view. After i add new items to the database it cannot be seen in the datagridview while the program is running. I have to stop the program and run it again just to see the changes i made.

Here is how i load the datagridview:

Public Class frmSupplies

Private Sub frmSupplies_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    'TODO: This line of code loads data into the 'SuppliesDataSet.product_info' table. You can move, or remove it, as needed.
    Me.Product_infoTableAdapter.Fill(Me.SuppliesDataSet.product_info)
End Sub

How can i view the newly added items while the program is still running?

Answer 1

I created a module that will call the “refresh” function for the datagridview. I added a new module to my project and added this codes:

Imports System.Data.OleDb
Module Module1
Dim con As New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source= database path")
Sub REFRESHDGV()
    Dim sql As String
    sql = "SELECT * FROM [product info]"
    Dim adapter As New OleDbDataAdapter(sql, con)
    Dim dt As New DataTable("product info")
    adapter.Fill(dt)
    Form1.dgv1.DataSource = dt
End Sub
End Module

Hope this helps others!
