• Make a Linq-to-SQL Generated User Class Inherit from MembershipUser

  - by Adam Albrecht

  I am currently building a custom Membership Provider for my Asp.net MVC website. I have an existing database with a Users table and I'm using Linq-to-Sql to automatically generates this class for me. What I would like to do is have this generated User class inherit from the MembershipUser class so I can more easily use it in my custom Membership Provider in methods such as GetUser. I already have all the necessary columns in the table. Is there any way to do this? Or am I going about this the completely wrong way? Thanks!

• How do I get the value of a DynamicControl?

  - by Telos

  I'm using ASP.NET Dynamic Data functionality to do something a little weird. Namely, create a dynamic list of fields as children of the main object. So basically I have Ticket.Fields. The main page lists all the fields for Ticket, and the Fields property has a DynamicControl that generates a list of controls to collect more data. The tricky part is that this list ALSO uses Dynamic Data to generate the controls, so each field can be any of the defined FieldTemplates... meaning I don't necessarily know what the actual data control will be when I try to get the value. So, how do I get the value of a DynamicControl? Do I need to create a new subclass of FieldTemplate that provides a means to get at the value?

• Is it possible to bind data asynchronously between two dropdownlists in a view?

  - by user252160

  I'd like to achieve the following effect using ASP.NET MVC and JQuery. I've got a drop down list displaying a list of Countries. I want to make it so that when I change the value of the country, a new drop down list appears below it, showing a list of companies whose country of origin is the particular selected company. The thing is that I do not want to rely too much on controller actions because I'm using it in a Template Helper which is a "headless" view. Can I bind it somehow?

• IIS 7.0 - Every site suddenly redirecting root request to forms authentication

  - by Pittsburgh DBA

  Suddenly, IIS 7.0 is redirecting every request for the root of any domain hosted on the box to ~/Account/Logon, which is our Forms Authentication redirect. Additionally, some JavaScript and image requests are being similarly redirected, but not other aspx pages. This is not desirable. Nobody will admit to changing anything. Any ideas? EDIT: It turns out that something has gone wrong with the disk permissions. Can anyone point me to the way things are supposed to be in Windows Server 2008 for a standard ASP.Net installation? The disk permissions are out of whack now.

• Clone DB table row through MVC in SQL Server

  - by sslepian

  Is there a simple solution for duplicating table rows in SQL Server as well as all table rows with foreign keys pointing to the cloned table row? I've got a "master" table and a bunch of "child" tables which have a foreign key into the ID of the master table. I need to not only create a perfect copy of the master table, but clone each and every child table referencing the master table. Is there a simpler way to do this than creating a new row in the master table, copying in the information from the row to be cloned, then going through each child table and doing the same with each row pointing to the cloned row in the master table? I'm using a SQL Server 2005 Database accessed through C# ASP.net MVC 1.0.

• How do I manually log a user in with a MembershipProvider?

  - by Allen

  I'm experimenting with writing my own custom MembershipProvider in asp.net and I want to roll my own login page. We do some fairly special stuff at login time so we can't use the default login control so I need a way to manually log a user in. So far I haven't found anything on how to write your own login control so I'm here, wondering how I can manually log a user in via a MembershipProvider. I've tried Membership.ValidateUser("user", "pass"); and while that does call ValidateUser() on my custom MembershipProvider, and it does return true, it doesn't actually log me in. Btw I'm fairly new to the whole MembershipProvider stuff so if I'm not even on the right wavelength, feel free to let me know.

• Using *.html extension in dynamic UR's for SEO

  - by lostaman

  Hi all My situation is. I have a project planned to be built on ASP.NET MVC 2. And one of the major requirements is SEO optimization. A customer wants to use static-like URLs that end up with .html extension for this project that make URLs more SEO friendly. E.g. "mysite.com/about.html " or "mysite.com/items/getitem/5.html" etc. I wonder is there any benefit from SEO perspective to use .html extension in dynamic URLs? Are Google and other search engines rank work better with such URLs?

• aspnet_regsql not working at all

  - by user252160

  I would like to create the ASP.NET User database template on a database of my own, because I'd like to fully untegrate the user system with the rest of my DB. As I've read, i needed to use the aspnet_regsql tool. I put all the options (because my database is running on SQLEXPRESS and is in an mdf file in my project's folder). the program starts and seemingly runs without any errors, however, when I open the database after that, not tables or stored procedures have been added. One more thing: I did one more test. I intentionally gave the -d option a wrong mdf file address, and surprisingly, the program "finished" correctly, yet no file was crated or modified whatsoever.

• How to model my database when using entity framework 4?

  - by Junior Ewing

  Trying to wrap my head around the best approach in modelling a database when we are using Entity Framework 4 as the ORM layer. We are going to use asp.net mvc 2 for the application. Is it worth trying to model using the class diagram modeller that comes with Visual Studio 2010 where you graphically configure your models into the EDMX file and then generate out the database structure? I have run into a bunch of non trivial issues and for complex many to many mappings or multi primary key entities the answer is not that obvious even after poking around a while with the tools. I figure its easy at this point to give up and start modelling the DB using real, working DB modelling tools and then try to generate out the EDMX from the database, rather than trying to do the model first approach.

• How to find what ActiveX control is referred on a web page?

  - by Sly

  I have developed a web application (ASP.NET Web Forms). One of my customer has very restrictive policies. When he accesses the web page, IE shows this message: Your security settings do not allow Web sites to use ActiveX controls installed on your computer. This page may not display correctly. As far as I know, we don't use ActiveX controls on our page. I did a "View Souce" and did not find anything suspect. How can I find what part of my page refers to an ActiveX. The application uses jQuery and a few jQuery plug-ins. Is there a tool/add-in like "Fire Bug" that I can use to list the ActiveX controls referred on a page?

• anyone know of a custom membership provider implementation that check password strength against in-b

  - by ronaldwidha

  I've got an Asp.net MVC app and before being able to go live, the IT have requested for us to comply with their password policy. The flexibility of AspnetSqlMembershipProvider doesn’t quite satisfy the requirement. The password strength and length rules are as follows: one lowercase one Uppercase one number and or special character 8 characters in length so far, aspnetsqlmembershipprovider is good... Not allowed to use: Dictionary words Names, real or fictional Plain language phrases Dates Telephone numbers Car registration numbers User IDs Postal codes Organization name Only the first 4 criteria are satisfied by the aspnetsqlmembershipprovider. Do you know of any third party products that offers this functionality (preferably in the form of a custom membership provider)?

• MVC on Server 2008 R2 - How?

  - by Redeemed1

  I have a new WIndows Server 2008 R2 x64 DataCentre with Framework 3.5 SP1 and Framework 4 installed. When I install my MVC application (VS 2008 MVC 2.0 using a Web Setup project installer) and browse to the application I get an error that System.Web.Mvc cannot be found. If I copy the relevant DLLs (System.Web.Mvc etc)into the bin directory the app runs up perfectly. I have checked everywhere for an installer but can only find the VS2008 related bits, no server runtime. How do I get ASP.Net MVC installed in this environment so that we don't have to Copy Local the dlls? Many thanks Brian

• What are the advantages of using J2EE over ASP.net?

  - by m_oLogin

  We are currently planning to launch a couple of internal web projects in the future. Our company's dev teams are mostly experienced in J2EE and have worked with it for years. Today, we have the choice of launching a couple of our projects on .net. I have checked out a couple of sources on the net, and it seems like the "J2EE vs ASP.net" combat brings out as much discord as the overseen "Apple vs Microsoft" or "Free Eclipse vs Visual Studio"... Nevertheless, I have been somewhat quite impressed with ASP.net's abilities to create great things with huge simplicity (for ex. asp.net ajax's demos). No more tons of xmls to play with, no more tons of frameworks to configure (we usually use the famous combo struts/spring/hibernate)... It just seemed to me that ASP.net had some good advantages over J2EE, but then again, I may speak by ignorance. What I want to know is this : What are the real advantages of using J2EE over ASP.net? Is there anything that cannot be done in ASP.net that can be done in J2EE? Once the frameworks are all in place and configured, is it faster to develop apps in J2EE than it is in .net? Are the applications generally easier to maintain in J2EE than in ASP.net? Is it worth it for some developpers to leave their J2EE knowledge on the side and move on to ASP.net if it does exactly the same thing?

• Better performance to Query the DB or Cache small result sets?

  - by user169867

  Say I need to populate 4 or 5 dropdowns w/ items from a database. Each drop down will have < 15 items in it. These items almost never change. Now I could query the DB each time the page is accessed or I could grab the values from a custom class that would check to see if they already exist in ASP.Net's cache and only if they don't query the DB to update the cache. It's trivial for me to write but I'm unsure if the performace would be better or not. I think it would be (although not likely anything huge). What do you think?

• Can you specify if aspnet_compiler.exe creates a debug or release build?

  - by user169867

  I wish to compile my asp.net MVC application using aspnet_compiler.exe from the comandline to speed up cold startup. I'm wondering how it determines if it should do a release or debug build. Is it always release? Does it depend on what the web.config file says when you run aspnet_compiler.exe? What happens to an application that's been compiled w/ aspnet_compiler.exe if someone changed the bug attribute in the web.config file after it has been published? Any clarification on this would be greatly appreciated.

• How to handle Clean URIs in Classic ASP using PATH_INFO?

  - by Mario

  I'm trying to handle Clean URIs in a Classic ASP application. In PHP, I was able to use URIs like http://example.com/index.php/foo/bar/baz and have /foo/bar/baz available in the PATH_INFO environment variable. (I usually add a rewrite rule so I do not need the index.php segment) However, I don't seem to be able to mimic this in Classic ASP. If I try http://example.com/index.asp/foo/bar/baz, I get a 404 error. Is there a way to add a path after the index.asp segment and get the PHP like behaviour in ASP? Note: I'm currently using the workaround of rewriting URLs of the form: http://example.com/foo/bar/baz/ to index.asp?path=/foo/bar/baz since I can't seem to get index.asp/foo/bar/baz to work.

• How to configure IIS to serve my 404 response with my custom content?

  - by Marek

  This question is related to this, hopefully better phrased. I would like to serve a custom 404 page from ASP.NET MVC. I have the route handler and all the infrastructure set up to ensure that nonexistent routes are handled by a single action: public ActionResult Handle404() { Response.StatusCode = 404; return View("NotFound"); } Problem: IIS serves back its own content (some predefined message) when I set Response.StatusCode to 404 before returning the content. On the VS development web server, this works as intended - the status code of the HTTP response is 404 while my content (the NotFound view) is served. I believe that when the IIS processing pipeline sees that the application returns 404, it simply replaces the whole response with its own. What setting in IIS affects this behavior? I do not have access to the IIS installation so I can not investigate this - however, I can ask the hosting provider to tweak the configuration for me if I know what exactly needs to be changed.

• Passing a JavaScript variable to a helper method

  - by Brendan Vogt

  I am using ASP.NET MVC 3 and the YUI library. I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such: window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))'; Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like: var formatActionLinks = function (oCell, oRecord, oColumn, oData) { var newsId = oRecord.getData('NewsId'); oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>'; };

• Passing Data from Usercontrol to controller

  - by nitinkhanna

  Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

• User management with aspnet membership provider

  - by 109221793

  Hi guys, Just a general question really. I have taken on the management of an application written in C# MVC that uses the asp.net membership api. With this a user can register, change their password, etc. My application consists of two areas, administrator and user. This adminstrator's area has lots of custom admin functionality relating to the application, however has no functionality utilizing the membership api. I want to be able to use the membership api for user management functions such as resetting a password of a user who has forgotten theirs, lock users out, etc. Are there any resources or articles out there that delve into this aspect of using the membership api? Any help would be appreciated :) thanks

• Will using https prevent client from accessing any confidential data inside JavaScript

  - by saveing saving

  I am working on an asp.net mvc web application, on the view i wrote the following JavaScript which calls an external web service :- <script type="text/javascript"> $(function() { $.getJSON("https://MyERPsystem.com/jw/web/json/hr/getsalary/byid?master_username=superadmin&password_hash=9449B5ABCFA9AFDA36B801351ED3DF66&employeeid=A200121", { //code goes here }, function(data) { $.each(data.items, function(i,item){ //code goes here }); }); }) </script> So if the external web service implements https, then does this means that the master_username and password_hash inside the javaScript cannot be seen by external users?

• routing difficulty

  - by user281180

  Part of my application maps resources stored in a number of locations onto web URLs like this: http://servername/Issue.aspx/Details?issueID=1504/productId=2345 Is it possible to construct an MVC route that matches this so that I get the path in its entirety passed into my controller? Either as a single string or possibly as an params style array of strings. In my Global.aspx I have routes.MapRoute( "Issue", "Issue/{Details}", new { controller = "Issue", action = "Details" }, new { issueId = @"\d+", productId = @"\d+" } ); I have tried the code RouteValueDictionary parameters = new RouteValueDictionary { {"Controller", "Issue"},{ "action", "Details" }, { "issueId", Test.ID }, {"productId", Test.Project.ID} }; VirtualPathData vpd = RouteTable.Routes.GetVirtualPath(null, parameters); var test = vpd.VirtualPath; test value is /Issue.aspx/Details?issueId=1504&productId=3625. How to generate URLs Using ASP.NET Routing and sends it to users and they should be able to open the page by clicking on the generated link. However, here the servername isn`t included.
