Try this code it works for me.

Dim i As Integer ' The variable i gives the number of records updated
       'create a table
       Dim dt As New DataTable
       ' create a data adapter
       Dim da As New OleDbDataAdapter
       Try
           'retrieving and populating datagridview
           '***************************************
           ' your statements
           '***************************************

           'Populates the datatable
           da.Fill(dt)
           'DataBindings
           Your_DataGridView.DataSource = dt
           i = da.Update(ds, "WorkRecords")
           MsgBox("Changes made successfully, " & i & " records updated!", MsgBoxStyle.OkOnly, "Success")

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