Your declaring your propertie and saying that the return value is going to by a Panel. Change it to
public bool SidebarPanel1

Hello Sir,
i know how to use the FindControl to acces the control from master page. if you have seen my code in the master page i have something like this for a label1

//for label1
    public string SidebarLabel1
    {
        get
        {
            return Label1.Text;
         }
        set
        {
            Label1.Text = value;
        }
    }

and as you have seen in from my earlier post how  i am accessing SidebarLabel1 in the aspx page. i was hoping to do something along that line sir. is is possible to do that
Thanks once again

So, your saying that setting the visible propertie to false, it don't hide the panel right?
If so, try yourpanel.Style.Add("display","none")

For DDL's you can use Style.Add("display","none")
