更新数据库后刷新Datagridview

Question

我正在更新表单中的数据库并再次加载datagridview但datagridview没有更新。我试过的代码如下。

这是我的销售条目表单中的代码，如果已售出商品，则应减少数量，但在保存销售后，库存不会在网格中更新。

 Private Sub loadallitembtch()
    dgvsearchitem.ScrollBars = ScrollBars.Vertical
    On Error Resume Next
    con = New OleDbConnection(connectionString)
    con.Open()

    Dim ds As DataSet = New DataSet
    Dim adapter As New OleDb.OleDbDataAdapter

    adapter.SelectCommand = New OleDb.OleDbCommand(sqlstr, con)

    adapter.SelectCommand.Parameters.AddWithValue("@date1", globals.fedate)
    adapter.SelectCommand.Parameters.AddWithValue("@date2", globals.fsdate)
    adapter.SelectCommand.Parameters.AddWithValue("@comcode", compcode)
    adapter.Fill(ds)
    dgvibatch.Refresh()



    If ds.Tables(0).Rows.Count > 0 Then

        dgvibatch.Columns("Stock").Width = 50
    Else
        ds.Dispose()

    End If
    con.Close()
