Dynamically create ASP.net Submit LinkButton using panel
I am trying to implement an application that will dynamically create a list box with a button next to each item in that list. I can partially do this by using a Panel control in the aspx page and dynamically adding the html to the code behind. I am having problems dynamically adding a LinkButton that will do database work based on what id it is. Is this possible with what I have ?:
ASPX:
<asp:Panel ID="ItemPanel" runat="server">
</asp:Panel>
code behind:
...
StringBuilder sb = new StringBuilder();
string UserID;
while (dr.Read())
{
UserID = Convert.ToInt32(dr["UserID"]);
sb.Append("<div><b class='template'></b>");
//Create LinkButton with event and code behind function
}
ItemPanel.Controls.Add(new LiteralControl(sb.ToString()));

Edit (after OP's comment)
The purpose of posting this link is to give you an idea of how to create a control dynamically. Since you are asking, here is a simple bare bone ASPX page that creates a LinkButton and attaches an event handler for the event Click
. Not sure what you mean by "server changes".
<%@ Page Language="C#" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
LinkButton lnk1 = new LinkButton();
lnk1.Text = "Click me!";
//lnk1.PostBackUrl = "SomeOtherPage.aspx";
// Use the eventhandler to perform redirection,
// instead of the PostBackUrl to show it works.
lnk1.Click += new EventHandler(lnk1_Click);
// Add control to container:
pnl1.Controls.Add(lnk1);
}
void lnk1_Click(object sender, EventArgs e)
{
Response.Redirect("SomeOtherPage.aspx");
}
</script>

<head>
<title>Untitled Page</title>

<body>
<form id="form1" runat="server">
