POHaving trouble with Asp.net MVC passing in a querystring as a parameter
text
Body
copied!<p>I have a login page. In my web.config I setup a loginUrl so that if a user tries to go to an "Authorized" page and are not authorized they will get redirected to the login page.</p> <p>Now I noticed when this happens and the user gets redirected from a "Authorized" page the url from the page they are getting redirected from gets appended to the login url. </p> <p>So that way when they do login I can use that I can send them back to the page they where trying to get too.</p> <p>So this is how the Url would look:</p> <p><a href="http://localhost:2505/CMS_Account/LogOn?ReturnUrl=%2fCMS_Home%2fIndex" rel="nofollow noreferrer">http://localhost:2505/CMS_Account/LogOn?ReturnUrl=%2fCMS_Home%2fIndex</a> </p> <p>So I am trying to capture the ReturnUrl querystring part as a parameter in my View.</p> <p>But I can't get it took work. </p> <p>So I found out if I change my Form for the login to this:</p> <pre><code><% using (Html.BeginForm()) ........ </code></pre> <p>Then I can capture the ReturnURl for some reason no problem.</p> <p>However how I have it right now I have this:</p> <pre><code><% using (Html.BeginForm("Login","Authentication",FormMethod.Post,new { id = "frm_Login"})) ..... </code></pre> <p>Once I try to pass the parameters into the BeginForm it stops capturing the ReturnUrl.</p> <p>I don't know why it stops. Some people say that it is because I am using the default route and somehow if you don't put anything in the beingForm it magically can figure out the ReturnUrl with the default url.</p> <p>Soon as you put something in BeginForm it seems to get dumb and you need to give it a route to tell it what to do.</p> <p>I don't know how to write this route though. I tried quite a few different combinations and they all failed and everyone who tells me right a route never tell me how it should look like. </p> <p>So I don't know what to try anymore.</p> <p>What I tried</p> <pre><code>routes.MapRoute( "CMS_Account", // Route name "CMS_Account/{action}/{ReturnUrl}", // URL with parameters new { controller = "CMS_Account", action = "LogOn",} // Parameter defaults ); routes.MapRoute( "CMS_Account", // Route name "CMS_Account/{action}/{ReturnUrl}", // URL with parameters new { controller = "CMS_Account", action = "LogOn", ReturnUrl = ""} // Parameter defaults ); routes.MapRoute( "CMS_Account", // Route name "{controller}/{action}/{ReturnUrl}", // URL with parameters new { controller = "CMS_Account", action = "LogOn", ReturnUrl = ""} // Parameter defaults ); routes.MapRoute( "CMS_Account", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "CMS_Account", action = "LogOn", id = ""} // Parameter defaults ); routes.MapRoute( "CMS_Account", // Route name "{controller}/{action}/", // URL with parameters new { controller = "CMS_Account", action = "LogOn"} // Parameter defaults ); </code></pre>

Querying!
