    <p>I have a problem. I'm trying to make some panels, and in these panels I would like to have some linkbuttons, when the user click a linkbutton of a panel a textbox will appear in that panel, when I click in another linkbutton the textboxes of that panel also appear without problem but when I click in the other linkbutton the texboxes created in the previous panel disappears. </p> <p>Here is my code:</p> <pre><code>public partial class _Default : Page { Label myLabel1; Label myLabel2; protected void Page_Load(object sender, EventArgs e) { myLabel1 = new Label(); myLabel2 = new Label(); Panel1.Controls.Add(myLabel1); Panel2.Controls.Add(myLabel2); if (!Page.IsPostBack) { //Remove the session when first time page loads. Session.Remove("clicks"); Session.Remove("clicks2"); } } protected void LinkButton1_Click(object sender, EventArgs e) { int rowCount = 0; //initialize a session. rowCount = Convert.ToInt32(Session["clicks"]); rowCount++; //In each button clic save the numbers into the session. Session["clicks"] = rowCount; //Create the textboxes and labels each time the button is clicked. for (int i = 0; i &lt; rowCount; i++) { TextBox TxtBoxU = new TextBox(); TxtBoxU.ID = "TextBoxU" + i.ToString(); //Add the labels and textboxes to the Panel. Panel1.Controls.Add(TxtBoxU); } myLabel1.Text = rowCount + ""; } protected void LinkButton2_Click(object sender, EventArgs e) { int rowCount2 = 0; //initialize a session. rowCount2 = Convert.ToInt32(Session["clicks2"]); rowCount2++; //In each button clic save the numbers into the session. Session["clicks2"] = rowCount2; //Create the textboxes and labels each time the button is clicked. for (int i = 0; i &lt; rowCount2; i++) { TextBox TxtBoxU = new TextBox(); TxtBoxU.ID = "TextBoxU" + i.ToString(); //Add the labels and textboxes to the Panel. Panel2.Controls.Add(TxtBoxU); } myLabel2.Text = rowCount2 + ""; } } </code></pre> <p>And here is the other part:</p> <pre><code>&lt;form id="form1" runat="server"&gt; &lt;p&gt; Part I&lt;/p&gt; &lt;asp:Panel ID="Panel1" runat="server" Height="53px"&gt; &lt;asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click"&gt;Add to 1&lt;/asp:LinkButton&gt; &lt;br /&gt; &lt;asp:TextBox ID="TextBox1" runat="server"&gt;&lt;/asp:TextBox&gt; &lt;/asp:Panel&gt; &lt;asp:Panel ID="Panel2" runat="server" Height="51px"&gt; &lt;asp:LinkButton ID="LinkButton2" runat="server" OnClick="LinkButton2_Click"&gt;Add to 2&lt;/asp:LinkButton&gt; &lt;br /&gt; &lt;asp:TextBox ID="TextBox2" runat="server"&gt;&lt;/asp:TextBox&gt; &lt;/asp:Panel&gt; &lt;/form&gt; </code></pre>

    1. COYou have to rebuild dynamic controls on every postback. So even when LinkButton2 is clicked you have to run code from LinkButton1 for textboxes to exist

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.

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