I've got a page that uses a master page. The master page has 2 contentplaceholders on it. The page has content controls on it that correspond to the placeholders on the master page. I need to dynamically insert a usercontrosl into those content areas. I can't seem to get a reference to the content controls at run time so that I can insert the controls into them. See code below:
Master Page:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="Agile.Portal.Site1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
WebPage:
<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Agile.Portal.WebForm1" %>
<asp:Content ID="head" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="ContentPlaceHolder1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
</asp:Content>
Code:
protected override void OnInit(EventArgs e)
{
// YOU SUCK, you're always null!!!
System.Web.UI.WebControls.Content cnt = (System.Web.UI.WebControls.Content)this.FindControl("ContentPlaceHolder1");
Agile.Portal.Framework.BaseModule mod = (Agile.Portal.Framework.BaseModule)LoadControl("~/modules/HTMLModule/HtmlModule.ascx");
cnt.Controls.Add(mod);
base.OnInit(e);
}
