And?
Your question is what?
What is happening that shouldn't, or not happening that should?
Any error messages?

Hi,

You can define a property in master page like :

C#

public bool TestPanelVisible
{
    set
    {
          pnlTest.Visible = value;
    }
    get
    {
          return pnlTest.Visible;
    }
}

And in content page you can set this property to true/false when you want to show/hide the panel as :

C#

this.Master.TestPanelVisible = false;

In the content page you have to register Master using following tag:

<%@ MasterType VirtualPath="~/MasterPage.master" %>

Only then you will be able to access master page's property.

Hope this Helps :)

If the ID of panel is Panel1, use

C#

Panel pl = (Panel)Master.FindControl("Panel1"); 
pl.Visible = false;

What is the output you get when you put a breakpoint at: Panel pl = (Panel)Master.FindControl("Panel1");? What is pl? null?
