select master page at run time for a specific page

Question

I have an asp page employeeHome.aspx and I have two master pages adminMasterPage.master for Admin login and userMasterPage.master for normal user login as I have 2 types of user login one as Admin and other normal user. And I want to set adminMasterPage.master as a master page for employeeHome.aspx in case of normal user login (just for this page). How can I do this?

Answer 1

Put your code to change the master page in Page_PreInit event.

protected void Page_PreInit(object sender, EventArgs e) 
{
    this.MasterPageFile = "MasterPage.master";
}

Answer 2

Put the code at employeeHome.aspx page

 protected void Page_PreInit(object sender, EventArgs e)
        {
            if (Session["empCode"] != null)
            {
                if (Session["empCode"].ToString() != "0")
                {
                    this.MasterPageFile = Server.MapPath("adminMasterPage.master");
                }
            }
        }

Answer 3

You can change that by having the required master page file specified in the PreInit event, which is a part of the page life cycle..

protected void Page_PreInit(object sender, EventArgs e) 
{
    this.MasterPageFile = "adminMasterPage.master";  //For Admin

    //this.MasterPageFile = "userMasterPage.master";  - For Normal User
}

This worked this way and here what I did as suggest by @Iswanto San and made changes in the path.

protected void Page_PreInit(object sender, EventArgs e)
    {
        if (Session["IsEmporAdm"].ToString() == "0")
        {
            this.MasterPageFile = "~/StyleLibrary\\layout\\AdminMaster.Master";
        }
        else
        {
            this.MasterPageFile = "~/StyleLibrary\\layout\\UserMaster.Master";
        }
    }
