            CON.Open()
            CMD.ExecuteNonQuery()
            CON.Close()
            Me.Refresh()
            MsgBox("Existing Record Updated Successfully...")
        Catch
            If CON.State = ConnectionState.Open Then
                CON.Close()
            End If
            MessageBox.Show("Error Deleting data...")
            'MsgBox(ex.Message & " -  " & ex.Source)
            'MessageBox.Show(ex.Message)
        End Try
        CON.Open()
        STR = "SELECT * FROM StdMasterNew"
        CMD = New OleDbCommand(STR, CON)
        CMD.ExecuteNonQuery()
        CON.Close()

        'Moving to Last Record
        CurrentRow = DST.Tables("ClassMan").Rows.Count - 1
        ShowData(CurrentRow)
    End Sub

This is my Delete button code. But When I press it the record gets deleted but showing when I press BACK, NEXT, FIRST, LAST buttons. But when I re-compile it the record is deleted

What I have tried:

i have tried refreshing with
Me.Refresh
but useless...
