C# 无法从gridview中创建的动态文本框中读取

我是dotnet新手，只是尝试为网格视图动态添加一行文本框

加载页面时，网格视图将以只读方式加载数据

单击编辑按钮，第二行将加载文本框。我一直成功到这里。现在，在这些文本框中输入一些数据时，我无法读回c代码中的值

这是我的代码片段。谁能帮我一下吗

ASP代码：

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="justGrid._Default" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

    <br />

<asp:GridView ID="GridView1" runat="server">
</asp:GridView>

    <br />
    <asp:TextBox ID="TextBox1" runat="server" Width="170px"></asp:TextBox>
    <br />
    <br />
    <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="edit" />
    <br />
    <br />
    <asp:Button ID="Button2" runat="server" onclick="Button2_Click" Text="save" />
    <br />

</asp:Content>

C代码：

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                staticTable();
            }
            bindGrid();
        }
        protected void staticTable()
        {
            string[] NamesArray = new string[] { "RAM", "SAM", "TOM", "JERRY" };
            DataSet ds = new DataSet();
            DataTable dt = new DataTable();
            dt = ds.Tables.Add();
            dt.Columns.Add("Names", typeof(string));
            for (int j = 1; j <= 5; j++)
            {

                dt.Columns.Add("" + j, typeof(string));

            }
            foreach (string l in NamesArray)
            {
                dt.Rows.Add(l);
            }
            dt.Rows[0][1] = "S";
            dt.Rows[0][2] = "P";
            dt.Rows[0][5] = "P";
            dt.Rows[1][2] = "S";
            dt.Rows[1][4] = "P";
            dt.Rows[2][3] = "S";
            dt.Rows[3][1] = "U";
            dt.Rows[3][5] = "P";

            ViewState["CurrentTable"] = dt;
            GridView1.DataSource = ds;
            // GridView1.DataBind();

        }
        protected void bindGrid()
        {
            DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];

            GridView1.DataSource = dtCurrentTable;
            GridView1.DataBind();

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            for (int k = 1; k <= 5; k++)
            {
                TextBox tb1 = new TextBox();
                tb1.Attributes.Add("runat", "server");
                tb1.Width = 15;

                tb1.ID = "TBID" + k;
                tb1.Text = GridView1.Rows[1].Cells[k].Text.Trim().Replace("&nbsp;", string.Empty);

                GridView1.Rows[1].Cells[k].Controls.Add(tb1);
            }
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            TextBox box1 = (TextBox)GridView1.Rows[1].Cells[1].FindControl("TBID1");
            TextBox1.Text = box1.Text;
        }

    }

注意：仅出于测试目的..我试图在文本框中显示第二行第一列的值。

嗨，安东尼，谢谢你的回复…我也试过了。但仍然无法读取文本框值。

foreach (GridViewRow row in GridView1.Rows)
{    
    TextBox box1 = row.FindControl("TBID") as TextBox;
    if (box1 != null)
    {
        string value = box1.Text;
    }
 }
