Question

i have master page that have no panels. i would like to use facade pattern to view appropriate panel or set of panel while user clicks link button of content place holder page.

while on first account load (Initial state),first panel will be visible and others are off, while user clicks link button of landing page, second panel visible and others are off.

how ever i create this base class newManageClass:

public class newManageClass : System.Web.UI.Page
    {
        public Panel Panel_User_Photo { get; set; }
        public Panel Panel_Search { get; set; }
        public Panel Panel_notification { get; set; }
        public Panel Panel_companymanagement { get; set; }
        public Panel Panel_omwealthmanagement { get; set; }
        public Panel Panel_newsletter { get; set; }

        public newManageClass()
        {
            Panel_User_Photo = new Panel();
            Panel_Search = new Panel();
            Panel_notification = new Panel();
            Panel_companymanagement = new Panel();
            Panel_omwealthmanagement = new Panel();
            Panel_newsletter = new Panel();
        }
        public void OnPageLoad()
        {
            Panel_User_Photo.Visible = true;
            Panel_Search.Visible = true;
            Panel_notification.Visible = true;
            Panel_companymanagement.Visible = false;
            Panel_omwealthmanagement.Visible = false;
            Panel_newsletter.Visible = false;
        }
        public void CompanyManagementClick()
        {
            Panel_User_Photo.Visible = false;
            Panel_Search.Visible = true;
            Panel_companymanagement.Visible = true;
            Panel_notification.Visible = false;
            Panel_omwealthmanagement.Visible = false;
            Panel_newsletter.Visible = false;
        }
        public void OmWealthManagementClick()
        {
            Panel_User_Photo.Visible = false;
            Panel_Search.Visible = true;
            Panel_notification.Visible = false;
            Panel_companymanagement.Visible = false;
            Panel_omwealthmanagement.Visible = true;
            Panel_newsletter.Visible = false;
        }
        public void NewsLetterManagementClick()
        {
            Panel_User_Photo.Visible = false;
            Panel_Search.Visible = false;
            Panel_notification.Visible = false;
            Panel_companymanagement.Visible = false;
            Panel_omwealthmanagement.Visible = false;
            Panel_newsletter.Visible = true;
        }
        public void UserManagementClick()
        {
            Panel_User_Photo.Visible = false;
            Panel_Search.Visible = true;
            Panel_notification.Visible = false;
            Panel_companymanagement.Visible = false;
            Panel_omwealthmanagement.Visible = false;
            Panel_newsletter.Visible = false;
        }
        protected override void OnPreInit(EventArgs e)
        {
            base.OnPreInit(e);
            if (Session["MyTheme"] == null)
            {
                Session.Add("MyTheme", "blue");
                Page.Theme = ((string)Session["MyTheme"]);
            }
            else
            {
                Page.Theme = ((string)Session["MyTheme"]);
            }
        }
    }

after all that i implement this class as helper class to master page:

Solution

I am not sure if this is what you are looking for but here's what I tried

newManageClass.cs

using System.Web.UI.WebControls;

public class newManageClass
{
    public Panel Panel1 { get; set; }    
    public Panel Panel2 { get; set; }    
    public Panel Panel3 { get; set; }

    public void OnPageLoad()
    {
        Panel1.Visible = true;
        Panel2.Visible = true;
        Panel3.Visible = true;
    }

    public void button1()
    {
        Panel1.Visible = true;
        Panel2.Visible = false;
        Panel3.Visible = false;
    }

    public void button2()
    {
        Panel1.Visible = false;
        Panel2.Visible = true;
        Panel3.Visible = false;
    }

    public void button3()
    {
        Panel1.Visible = false;
        Panel2.Visible = false;
        Panel3.Visible = true;
    }
}
