I created a very simple user control which contains lable and drag the
control to page

<%@ Page language="c#" Codebehind="Validate.aspx.cs" AutoEventWireup="false"
Inherits="Learning.Validate" %>
<%@ Register TagPrefix="uc1" TagName="GroupFilesManager"
Src="GroupFilesManager.ascx" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>Validate</title>
<meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
<meta content="C#" name="CODE_LANGUAGE">
<meta content="JavaScript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5"
name="vs_targetSchema">
</HEAD>
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<uc1:GroupFilesManager id="oGroupFilesManager"
runat="server"></uc1:GroupFilesManager></form>
</body>
</HTML>

in cs file i define the control object as GroupFileManager oGroupFilesManager;
but when try to use a function in
oGroupFilesManager it null??? why
 
Hi Raed Sawalha,

Try to declare it as protected member:
protected GroupFileManager oGroupFilesManager;

If you declare it as "protected" member, then the ASP.NET runtime will "know"
that the control declared on your WebForm is inherited from the object
declared in its code-behind page. Otherwise, the object declared in the
code-behind will be an independent object.
