如何隐藏TextBox标题

我希望能够在我的网络表单上隐藏文本框标题，我能够隐藏textBoxes但不能隐藏Caption。你能告诉我我错过了什么吗？

protected void Page_Load(object sender, EventArgs e)
{
if (cmdbox_TypePayment.SelectedIndex == 0)
{
    txt_Carte.Visible = false;
    txt_CarteNum.Visible = false;
    txt_CarteDate.Visible = false;
    txt_CarteCCV.Visible = false;
}
}
protected void cmdbox_TypePayment_SelectedIndexChanged(object sender, EventArgs e)
{
if (cmdbox_TypePayment.SelectedIndex == 0)
{
    txt_Carte.Visible = false;
    txt_CarteNum.Visible = false;
    txt_CarteDate.Visible = false;
    txt_CarteCCV.Visible = false;
}

 else if (cmdbox_TypePayment.SelectedIndex == 1)
{
    txt_Carte.Visible = true;
    txt_CarteNum.Visible = true;
    txt_CarteDate.Visible = true;
    txt_CarteCCV.Visible = true;
}
}

为标签设置 ID 并将其隐藏在同一个函数中。假设标签有ID lblCaption ..

protected void cmdbox_TypePayment_SelectedIndexChanged(object sender, EventArgs e)
{
    if (cmdbox_TypePayment.SelectedIndex == 0)
    {
       lblCaption.Visible = false;
       txt_Carte.Visible = false;
       txt_CarteNum.Visible = false;
       txt_CarteDate.Visible = false;
       txt_CarteCCV.Visible = false;
    }

    else if (cmdbox_TypePayment.SelectedIndex == 1)
    {
       lblCaption.Visible = true;
       txt_Carte.Visible = true;
       txt_CarteNum.Visible = true;
       txt_CarteDate.Visible = true;
       txt_CarteCCV.Visible = true;
    }
}
