I have given the particular permission for the particular user.
Only that menu will be enabled which permission is set for that user.
I have two problems….
1) Menu item should be invisible rather than disable
2) If any User copy the page name which it has no access and can open it..
Suggest any….(urgent)
you can manage the menu security by using ASP.NET Site-Map Security Trimming but if you want to prevent the uses from accessing the page through the url you can use put it inro your web.config file like:
