How to avoid hard-coding the Reference for a UserControl?
Question
I'd like to know whether or not there is a dynamic way to avoid hard-coding the Reference for a UserControl or by "USING"?
<%@ Reference Control="~/UserControl.ascx" %>
using UserControl;
I'm seeking a way to dynamically add References to UserControls to the page from code behind.

If I have understood your question correctly, this should do what you want to do-
Default.aspx
<!DOCTYPE html>
<html>
<head runat="server">
<title>Dynamic User Control Test</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<h1>Dynamic User Control Test</h1>
<asp:PlaceHolder ID="UserControlPlaceHolder" runat="server"></asp:PlaceHolder>
</div>
</form>
</body>
</html>
Default.aspx.cs
using System;
using System.Web.UI;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
UserControl uc = Page.LoadControl("~/UserControl.ascx") as UserControl;
if (uc != null)
{
UserControlPlaceHolder.Controls.Add(uc);
}
}
}
UserControl.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="UserControl.ascx.cs" Inherits="UserControl" %>
<p>Here is some content inside the user control</p>
UserControl.ascx.cs (this isn't needed if the UserControl is static and contains no solution specific code)
using System;
public partial class UserControl : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
This will only work with controls that are dynamically added to the page though.
