I answered my own question. I had recently copied a file within the same application. It seems the object control reference gets confused between the new, old file and old file code behind.

Here is where I found the answer... http://simonhibbard.wordpress.com/2007/03/10/aspnet-object-does-not-exist-in-the-current-context-really/

you probably need to do a MasterPage.Findcontrol(...

Take a look at Rick's article on this.

Ok, I put a label control in a regular page and it worked fine. My guess is... is that the page is a content page with a master page for headers and menus?

There must be some other issue. see if you can reduce the size of your page and figure out what is going on. Here is a simple sample that works with label visibility.

@ Page Language="C#" %>

DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

script runat="server">

protected void Page_Load(object sender, EventArgs e)

{

Label1.Visible =

true;

}

script>

html xmlns="http://www.w3.org/1999/xhtml" >

head runat="server">

<title>Untitled Page</title>

head>

body>

<div>

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

</div>

</form>

body>

html>

Control Visibility

I have two controls a hyperlink and label.

For some reason, I can set the visbility of the hyperlink control onload but it doesn't work for a label control. I get....."label does not exist in the current context".

  if (!Page.IsPostBack)
        {

            if (securityid == User.SECURITY_LEVEL_ID_AO_dec)
            {
                Hyperlink1.Visible = false;
                Label1.Visible = false
                //Get ERROR on label visiblity setting
                                
            }
        }

Is it because the lable gets rendered elsewhere than the page load? If so where and which event?

Thanks.
