Load User Control Dynamically Using C#

In this article we will try to learn how we can load a user control dynamically using C#. So let's start by adding an .aspx page and a user-control on our page. We name this control as DummyControl.ascx. On the main page, we will add an asp panel, say pnlDynamicControl. So our page mark-up will look like the following: 

<form id="form1" runat="server">
       <div>
           <asp:Panel ID="pnlDynamicControl" runat="server">
           </asp:Panel>
       </div>
   </form>

Next, add some dummy text on the user-control. Now let's move into the code-behind of the page and write the code to load the user-control into the panel. We will do this by using the LoadControl method of the Page class. This method expects a parameter, which is the url of the user-control inside the project. So our code will look like the following: 

public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //Load the control
            Control _dummyUserControl = (Control)Page.LoadControl("DummyControl.ascx");

            // Add the control to the panel
            pnlDynamicControl.Controls.Add(_dummyUserControl);
        }
    }

That's it, we are done. Run the application and see the results:
