请教老师，下面这段代码写在timertick ，问题：textBox1是放在Panel控件上，产生的数据能显示，但无法保存到单元格里，如果不放在Panel，能正常记录内容

到单元格里，也能保存

e.Form.TimerEnabled = True
Dim Val As String = Rand.Next(100000)
Dim s As String = val.PadLeft(5, "2")
Dim txt As WinForm.TextBox = e.Form.Controls("TextBox1")
txt.text = s

Dim sdt As Date = Date.Now
While Date.Now < sdt.AddSeconds(10)
    Application.DoEvents
    e.Form.TimerEnabled = False
End While

试试

Dim txt As WinForm.TextBox = e.Form.Controls("TextBox1")
txt.text = s

txt.WriteValue
