I have designed a module that change master page dinamically based on user log-in privileges.
I followed this tutorial :
Everything works well. But only works on sharepoint home page. If try to go to other page like
_layouts/user.aspx
or
/_layouts/closeConnection.aspx
then the page would crash!
public class DynamicMasterPageModule : IHttpModule
{
public void Dispose()
{
}
public void Init(HttpApplication context)
{
context.PreRequestHandlerExecute += new EventHandler(context_PreRequestHandlerExecute);
}
void context_PreRequestHandlerExecute(object sender, EventArgs e)
{
Page page = HttpContext.Current.CurrentHandler as Page;
if (page != null)
{
page.PreInit += new EventHandler(page_PreInit);
}
}
void page_PreInit(object sender, EventArgs e)
{
Page page = sender as Page;
string pageNo = ConfigurationManager.AppSettings["MasterPageNo"];
if (page != null)
{
if (pageNo.Equals("1"))
{
page.MasterPageFile = "~masterurl/custom.master";
if (SPContext.Current != null)
{
SPContext.Current.Web.CustomMasterUrl = "/_catalogs/masterpage/custom1.master";
}
}
else if (pageNo.Equals("2"))
{
page.MasterPageFile = "~masterurl/custom.master";
if (SPContext.Current != null)
{
SPContext.Current.Web.CustomMasterUrl = "/_catalogs/masterpage/custom2.master";
}
}
else
{
page.MasterPageFile = "~masterurl/default.master";
if (SPContext.Current != null)
{
SPContext.Current.Web.MasterUrl = "/_catalogs/masterpage/default.master";
}
}
}
