ASP.NET动态ASP表与文本框 - 保存价值在ViewState中 [英] ASP.NET dynamic ASP Table with TextBoxes - Save Values in ViewState

问题描述

我有一个网站的.aspx用ASP表。在隐藏文件code我填补行，细胞和细胞中的表是ASP文本框。

I've a .aspx Site with a ASP Table. In the code behind file I fill the table with rows, cells and in the cells are ASP TextBoxes.

在第一次加载我装满价值的文本框从数据库中。但有人正在编辑的价值，并与创建的按钮提交页面后，有表的programmaticaly创建的行没有访问。

At the first load I Fill the TextBoxes with Values out of a database. But after someone is editing the value and submit the Page with a created button, there are no Access to the programmaticaly created rows of the table.

现在我已经看到了一些帖子，一个动态创建的ASP表过得去回传重置了。

now I have seen some postings that a dynamic created asp table is getting resetted by postback.

现在我有一个问题，我怎样才能得到这是由用户在网站上修改的数值？！

now I have a question, how can I get the values which are changed by users on the site?!

我试图重写与SaveViewState和LoadViewState，但页面加载但经过SaveViewState只叫不，如果有人点击一个按钮？

I tried to override the SaveViewState and LoadViewState, but SaveViewState is only called after the Page was loaded but not if someone is clicking a button?

我要保存用户点击一个按钮后，我可以使用他们在code中的文本框的数据。

I'd like to save the data of the Textboxes that i can use them in the code after the user clicked a button.

我该怎么办？

有3这里钥匙，前$ P $完美地@Alexander pssed。

There are 3 keys here, expressed perfectly by @Alexander.

下面是一个code例如：

Here is a code example:

 <%@ Page Title="Home Page" Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>


    <form runat="server">
        <asp:PlaceHolder ID="placeHolder1" runat="server" />
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Submit"/>
    </form>

code背后：

Code Behind:

using System;
using System.Collections.Generic;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : Page
{
    private static readonly List<String> _listOfThings = new List<String> { "John", "Mary", "Joe" };
    private List<TextBox> _myDynamicTextBoxes;


    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        _myDynamicTextBoxes = new List<TextBox>();
        var i = 0;
        foreach (var item in _listOfThings)
        {
            var tbox = new TextBox {ID = "TextBox" + (i++),Text=item};
            placeHolder1.Controls.Add(tbox); //make sure you are adding to the appropriate container (which must live in a Form with runat="server")
            _myDynamicTextBoxes.Add(tbox);
        }
    }

    protected void Button1_Click(Object sender, EventArgs e)
    {
        foreach (var tbox in _myDynamicTextBoxes)
        {
            Response.Write(String.Format("You entered '{0}' in {1}<br/>", tbox.Text, tbox.ID));
        }
    }
}
