Hi

I am running the following procedire after I make cahnges to my database
to refresh the DataGridView but it isn't refreshing
I use code
 Call Fill_Supplier_DGV()
            Me.Supplier_DataGridView.Refresh()
but even the refresh doesn't work. Should I delete everything first? How would I do this?
Sub Fill_Supplier_DGV()
        Try


            Dim sSQL As String

            sSQL = "SELECT * FROM Suppliers"

            Dim connection As New OleDbConnection(ConnectionString)
            Dim dataadapter As New OleDbDataAdapter(sSQL, connection)
            Dim ds As New DataSet()
            connection.Open()
            dataadapter.Fill(ds, "Suppliers_table")
            connection.Close()
            Me.Supplier_DataGridView.DataSource = ds
            Me.Supplier_DataGridView.DataMember = "Suppliers_table"

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

    End Sub

You need to empty the datagrid before resetting the DataSource. Set the DataSource to Nothing before reassigning a new value to it:
Me.Supplier_DataGridView.DataSource = Nothing
Me.Supplier_DataGridView.DataSource = ds
