如何隐藏文本框标题

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;
}
}

我希望能够在我的网络表单上隐藏文本框标题，我能够隐藏文本框但不能隐藏标题。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;
}
}

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;
}
}

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;
}
}

同时为标签设置一个ID，并将其隐藏在同一函数中。假设label有一个IDlblcoption

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;
}
}

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;
    }
}

不跟随你想做的事情。你的意思是隐藏文本框中的文本而不是文本框本身吗？你是指隐藏标签吗？如果是这样，则需要在标签上设置visible属性以隐藏它。这听起来像你提到的“文本框”有标签和文本框。我想隐藏文本框的标签我可能很厚，但你不是说你已经可以隐藏文本框了吗？只需引用“我可以隐藏文本框，但不能隐藏标题”：）将标签和文本框放在

中。然后将面板可见性设置为true/false。
