Solved: webusercontrol interact with aspx

Plese see my attached code for the main page and the user control.
Setting the user control lable is easy.
To set the lable in the main page we expose the lable text property via a public property.
You have to case th Page to an instance of the page in question to make this work.

Page
 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="UserControlMainPage.aspx.cs" Inherits="EEWebModelApp.UserControlMainPage" %>
 
<%@ Register src="MyUserControl.ascx" tagname="MyUserControl" tagprefix="uc1" %>
