Web 应用程序 ASP.Net C#.取消屏蔽文本框，也称为显示密码

Question

我正在尝试在我的文本框下方制作一个"显示密码"复选框 - 密码 以取消屏蔽 txtpassword 并显示字符。

protected void chkUnmask_CheckedChanged(object sender, EventArgs e)
    {
        if (chkUnmask.Checked == true)
        {
            txtPassword.TextMode = TextBoxMode.Password;
        }
        else
        {
            txtPassword.TextMode = TextBoxMode.Password;
        }
    }

每次复选框更改为选中和未选中时，我都使用 If-Else 条件更改文本框的行为。它在WindowsFormApp C#中工作正常，但在WebApp C#中 ASP.net 则不能，我试图重新启动Visual Studio和我的笔记本电脑，希望这只是一个错误，但仍然不起作用。我想知道我的编码是否错误。

如果条件是

txtPassword.TextMode = TextBoxMode.Password;
    }
  You need to change the TextBox mode for one of the conditions 
// I think you need to set break points and check if this line is being triggered
TextBox1.TextMode = TextBoxMode.SingleLine;
// you can try this code which works fine. Add a button, and a textbox and set its textmode to Password. Type something the then click the button. 
protected void Button1_Click1(object sender, EventArgs e)
{
    TextBox1.TextMode = TextBoxMode.SingleLine;
}
