Re: Redirect to corresponding page after LogIN

hi,

Are you using login control or textboxes for logging in? If you are using login control, then there will be a property "DestinationPageUrl", which you can set to the aspx page that you want to show after successful login

Re: Redirect to corresponding page after LogIN

Private Sub buttonLogin_Click (ByVal sender as object, ByVal e as system.eventargs) handles buttonLogin.Click

if textboxUserName.text = "admin" and textboxPassword.text = "password" then

Session("IsAuthenticated") = true

End If

End Sub

Report.aspx page

Private Sub Page_Load (Byval sender as object, Byval e as System.EventArgs) Handles Me.Load

if Session("IsAuthenticated") Is Nothing or Session("IsAuthenticated") <> true then

Response.redirect("~/Login.aspx", true)

End if

End Sub

Re: Redirect to corresponding page after LogIN

Use System.Web.Mvc.AuthorizeAttribute on your controller actions. It will redirect unauthenticated users to login page with ReturnUrl query string. User this query string to redirect users back to intended page after successful login.

Sorry, I didn't see properly. I thought you are using ASP.NET MVC

If you are using some custom logic for authenticating and redirecting user to login page. You can add original url in query string while redirecting to login page and redirect back to that page on successful login.

if you want to restrict users to certain pages based on their role(if any) then use membership. i am not able to get what you are trying to achieve. :(

Re: Redirect to corresponding page after LogIN

If you are using a session, u can check the session whether it is a null value using if loop..

if it is null then, redirect to login page..

As I said earlier, when you redirect not-loggedin user from Reports.aspx to Login.aspx, pass the url of report.aspx as a query string to login.aspx. After user logs in, check if there any url in query string. If yes, redirect user back to that url. In this case it's reports.aspx.

Hope this clears your doubt.

In Reports.aspx:

if(!IsLoggedIn) //Code to perform a check if a user is logged-in or not.
{
   Response.Redirect("Login.aspx?ReturnUrl=" + Request.Url.AbsoluteUri);
}

In Login.aspx:

//ToDo: Validate username & password

//if ReturnUrl exist in query string, redirect user to ReturnUrl page. Else, redirect user to default (home) page. 
if(!string.IsNullOrEmpty(Request.QueryString["ReturnUrl"]))
{
    string returnUrl = Request.QueryString["ReturnUrl"];
    Response.Redirect(returnUrl);
}
else
{
    Response.Redirect("Home.aspx");
}

        }
    }
