Question

所以我必须在C＃中创建一个ASP.NET网站，其中包含一个用户表单，其中在文本框中填写了几条信息。我们的想法是让用户在表单中填写的内容显示在下面的文本框中。当用户键入时，文本应出现在文本框中，当输入更改时，应删除旧输入。我无法在下面的文本框中显示用户输入文本。我试图做的是在下面的表单和文本框中显示默认值，我成功地做到了这一点。因此，我有一个起点，但我不知道接下来该做什么。我包含了包含我的表单的.aspx页面和包含C＃代码本身的.cs文件。

aspx页面

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Models.aspx.cs" Inherits="Models" %>

Answer 1

试试这个：
aspx页面

//Add AutoPostBack="true"
<asp:TextBox ID="TextBox1" NAME="TextBox1" runat="server" AutoPostBack="true" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>

对其他控件做同样的事情。

cs page

    protected void Page_Load(object sender, EventArgs e)
    {
        //Add !IsPostBack
        if (!IsPostBack)
        {
            string input1;
            input1 = TextBox1.Text;
            TextBox2.Text = "Kauffman Road";
            TextBox3.Text = "Annville";
            TextBox4.Text = "Pennsylvania";
            TextBox5.Text = "17003";
            TextBox6.Text = "7173892295";
            TextBox8.Text = "Name: " + TextBox1.Text + "\n" + "Address: " + TextBox2.Text + "\n" + "City: " + TextBox3.Text + "\n" + "State: " + TextBox4.Text + "\n" + "Zip: " + TextBox5.Text + "\n" + "Phone: " + TextBox6.Text;
        }
    }
protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        TextBox8.Text = "Name: " + TextBox1.Text + "\n" + "Address: " + TextBox2.Text + "\n" + "City: " + TextBox3.Text + "\n" + "State: " + TextBox4.Text + "\n" + "Zip: " + TextBox5.Text + "\n" + "Phone: " + TextBox6.Text;
    }

TextBox8的文本将在TextBox1的文本被更改时更改。

将文本输入到表单中并在下面的文本框中显示它
