dynamic - Overwrite the LoginWidget and Set DestinationPageUrl dynamically in Sitefinity -

i want add custom code during login function, in particular want redirect user after login previous page.

for example: i'm on page , want download page, i'm not authorized. pops popup link login page. after successful login i'm on page a.

for purpose want overwrite loginwidged , set value to"this.destinationpageurl" dynamically.

i read similar issues here , here, there isn't example how overwrite loginwidget class.

i create customlogincontrol.cs file in project , register new custom control, after rendering on page, didn't work. login button not make nothing. i'm not sure have , of methods have overwrite.

namespace sitefinitywebapp.usercontrols {     public class customlogincontrol : telerik.sitefinity.web.ui.publiccontrols.loginwidget     {         protected override void render(system.web.ui.htmltextwriter writer)         {             this.destinationpageurl = "http://previouspage.com";              base.render(writer);         }     } } 

can give me example how overwrite class work properly.

version: sitefinity 5.0, claims-based authentication

i've done similar instead of overriding login control can subscribe , capture unauthorizedaccess event, send user login page redirect page query string parameter. you'll need add global.asax / global.asax.cs file project, add application_start function:

protected void application_start(object sender, eventargs e) {     bootstrapper.initialized += bootstrapperinitialized;             } 

then add these 2 functions:

private void bootstrapperinitialized(object sender, executedeventargs e) {     if (e.commandname == "bootstrapped")     {         eventhub.subscribe<iunauthorizedpageaccessevent>(onunauthorizedaccess);     } }  private void onunauthorizedaccess(iunauthorizedpageaccessevent unauthorizedevent) {     var manager = configmanager.getmanager();     string loginpage = manager.getsection<projectconfig>().defaultsite.frontendloginpageurl;      var redirectparam = unauthorizedevent.redirecturl.replace(string.format("{0}?returnurl=", loginpage), string.empty);      var escaped = uri.escapedatastring(redirectparam);      unauthorizedevent.httpcontext.response.redirect(string.format("{0}?returnurl={1}", loginpage, escaped)); } 

you need set default front end login page in settings under administration -> settings -> advanced -> project -> defaultsite , frontendloginpageurl setting.

this works me on 6.3 site, not sure if available in sitefinity 5 or not.
