    <p>I'm trying to get Text from a dynamically craeted server textbox. I'm just checking by getting the text into another textbox I placed in the aspx file, but all I get is always an empty string.. (I also tried another method that is enclosed in remark, but it doesn't work either)</p> <p>Here's the code behind:</p> <pre><code>public partial class Product_list : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { create_table(); } protected void create_table() { DBServices db1=new DBServices(); List&lt;Product&gt; list1 = db1.ReadProducts(); int id_number=1; int id_numer2 = 7; int id_number3 = 13; Table tbl = new Table(); tbl.ID = "tbl1"; this.Controls.Add(tbl); foreach (Product p1 in list1) { TableRow rw = new TableRow(); rw.ID = Convert.ToString(id_numer2); TableCell cell1 = new TableCell(); cell1.Text = p1.Name; TableCell cell2 = new TableCell(); Image img = new Image(); img.ImageUrl = p1.ImagePath; img.Height = 50; img.Width = 50; cell2.Controls.Add(img); TableCell cell3 = new TableCell(); cell3.ID = Convert.ToString(id_number3); TextBox textbox1 = new TextBox(); textbox1.ID = Convert.ToString(id_number); cell3.Controls.Add(textbox1); rw.Controls.Add(cell1); rw.Controls.Add(cell2); rw.Controls.Add(cell3); tbl.Controls.Add(rw); id_number++; id_numer2++; id_number3++; } } void save_list() { List&lt;Product&gt; Items_list = new List&lt;Product&gt;(); //TextBox aControl =Page.FindControl("1") as TextBox; /var tbl1 = this.Page.FindControl("tbl1") as Table; var tr = tbl1.FindControl("7") as TableRow; var td = tr.FindControl("13") as TableCell; var txt = td.FindControl("1") as TextBox; txt1.Value = txt.Text; } protected void Button1_Click(object sender, EventArgs e) { save_list(); } } </code></pre> <p>and here is the aspx code:</p> <pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="Product_list.aspx.cs" Inherits="Product_list" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;script runat=server&gt; public override void VerifyRenderingInServerForm(Control control) { } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div id="header"&gt; &lt;h1&gt;Items List&lt;/h1&gt; &lt;/div&gt; &lt;div id="prod_table" runat="server"&gt;&lt;/div&gt; &lt;div&gt; &lt;input type="text" runat="server" id="txt1" /&gt; &lt;asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COYou just created the textbox, you didn't set any value for its Text property, this is why you get an empty string.

    2. COI enter values for the textbox and then click the button, it should get the text I typed

    3. CO@apros gave you the right explanation, but if you don't need the data after the page is posted to the server, then you can just get the textbox's value client side. So you should change your code based on what you need to do next with your data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
