How to restrict the user to copy and paste
In this article I will explain how we can restrict the user or to block copy and paste the URL after the login.
For many occasions, we need not to allow users to copy / paste certain information.
As we know copy / paste can be done using either the right click of the mouse or using keys control+c, control+v etc.
So to disallow users to copy or paste we have to block by forcing the user to enter the login and password
This code will help you to block copy paste URL without login in the
same window or in another tab.
When you login the portal and leads to another page, for sale order it is very difficult to proceed, the client will enter the data at the same time, this will cause error.
This is C# Code for Web portal
Write this code in the pageload event of that particular aspx page
string PName = "";
if (Request.UrlReferrer != null)
PName = Request.UrlReferrer.Segments[Request.UrlReferrer.Segments.Length - 1];
if authentication is failing,
Check every Page if user is authenticated or not
Reference: Restrict copy and paste URL using ASP.NET
When user logs in to the system create a session key for the user and chk it all over to verify the identity of the session
if he/she directly pastes the URL the session key is not created,
so in this case u will chk for the session key, if it is not equal to null then only allow the user to login. else redirect him to the login page.
