• .Net MVC UserControl - Form values not mapped to model

  - by Andreas

  Hi I have a View that contains a usercontrol. The usercontrol is rendered using: <% Html.RenderPartial("GeneralStuff", Model.General, ViewData); %> My problem is that the usercontrol renders nicely with values from the model but when I post values edited in the usercontrol they are not mapped back to Model.General. I know I can find the values in Request.Form but I really thought that MVC would manage to map these values back to the model. My usercontrol: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<namespace.Models.GeneralViewModel>" %> <fieldset> <div> <%= Html.LabelFor(model => model.Value)%> <%= Html.TextBoxFor(model => model.Value)%> </div> </fieldset> I'm using .Net MVC 2 Thanks for any help!

• Generating %pc relative address of constant data

  - by Hudson

  Is there a way to have gcc generate %pc relative addresses of constants? Even when the string appears in the text segment, arm-elf-gcc will generate a constant pointer to the data, load the address of the pointer via a %pc relative address and then dereference it. For a variety of reasons, I need to skip the middle step. As an example, this simple function: const char * filename(void) { static const char _filename[] __attribute__((section(".text"))) = "logfile"; return _filename; } generates (when compiled with arm-elf-gcc-4.3.2 -nostdlib -c -O3 -W -Wall logfile.c): 00000000 <filename>: 0: e59f0000 ldr r0, [pc, #0] ; 8 <filename+0x8> 4: e12fff1e bx lr 8: 0000000c .word 0x0000000c 0000000c <_filename.1175>: c: 66676f6c .word 0x66676f6c 10: 00656c69 .word 0x00656c69 I would have expected it to generate something more like: filename: add r0, pc, #0 bx lr _filename.1175: .ascii "logfile\000" The code in question needs to be partially position independent since it will be relocated in memory at load time, but also integrate with code that was not compiled -fPIC, so there is no global offset table. My current work around is to call a non-inline function (which will be done via a %pc relative address) to find the offset from the compiled location in a technique similar to how -fPIC code works: static intptr_t __attribute__((noinline)) find_offset( void ) { uintptr_t pc; asm __volatile__ ( "mov %0, %%pc" : "=&r"(pc) ); return pc - 8 - (uintptr_t) find_offset; } But this technique requires that all data references be fixed up manually, so the filename() function in the above example would become: const char * filename(void) { static const char _filename[] __attribute__((section(".text"))) = "logfile"; return _filename + find_offset(); }

• iPad receiving memory warning with low memory use

  - by Fer

  I have an UIWebKit with a HTML, this HTML have several images and text, but just displaying it gives me the memory warning. So I did some tests: The same HTML with different images, fullsize, and after the same images but reduced 50% from it's original size, for the 50% reduced images, I went to preview and reduced all images in 50% The surprising part is the 50% test, you can see that even with 16 images, the memory peak is 4.90MB. That's really surprising. Notice that these values are not always the same, they change but there's not a huge difference between the tests. In the 50% issue, in the 8 and 16 images, although the memory is low, sometimes a memory warning appears, but the performance enhance is noticeable compared to the full size images standing still = memory after scrolling all article 1 Image = [standing still 5MB] [rotating 5.6MB] 2 Images = [standing still 6.99MB] [rotating 7.7MB] 3 Images = [standing still 9.04MB] [rotating 10.9MB] 4 Images = [standing still 10.89MB] [rotating 13.20MB] 8 Images = [standing still 23.14MB] [rotating 25.20MB] (sometimes crashes) 16 Images = [standing still 27.14MB and app crashes] 50% 1 Image = [standing still 3.2MB] [rotating 3.67MB] 2 Image = [standing still 3.2MB] [rotating 3.70MB] 3 Image = [standing still 3.3MB] [rotating 3.79MB] 4 Image = [standing still 3.3MB] [rotating 3.80MB] 8 Images = [standing still 4.29MB] [rotating 4,63MB] (sometimes crashes) 16 Images = [standing still 4.79MB] [rotating 4,90MB] (sometimes crashes) My question is: The app sometimes crashed with 16 small images. Why? The memory was much lower. What is the limit of memory use? These numbers are helpful if you also tell us the maximum. But, the maximum seemed different with the 50% size images. 13.2MB works for large images and 3.8 for small images. Anything higher sometimes crashes. That makes no sense.

• jQuery 1.4 Dynamically created images aspect ratio incorrect in IE8 and max-width

  - by Chris

  After upgrading to jQuery 1.4, when I try to add an image to a page dynamically using jQuery 1.4 in IE8, the image will lose the correct aspect ratio. This appears to affect only IE8 (IE7 and Firefox work fine) with jQuery 1.4 (1.3.2 works fine). Including the jQuery compatability file does not fix the problem. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" language="javascript" type="text/javascript"></script> <!-- Switching to 1.3.2 fixes the problem --> <!--<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" language="javascript" type="text/javascript"></script>--> <script type="text/javascript"> $(document).ready(function() { var dynImg = $('<img></img>').attr('src', 'http://www.google.com/intl/en_ALL/images/logo.gif'); $('body').append(dynImg); }); </script> <style type="text/css"> img { max-width: 5em; } </style> </head> <body></body></html>

• GWT JsonpRequestBuilder Timeout issue

• jQuery AJAX Character Encoding Problem

  - by Salty

  Hi everyone, I'm currently coding a French website. There's a schedule page, where a link on the side can be used to load another day's schedule. http://aquate.us/film/horaire.html (At the moment, only the links for November 13th and November 14th work) Here's the JS I'm using to do this: <script type="text/javascript"> function load(y) { $.get(y,function(d) { $("#replace").html(d); mod(); }); } function mod() { $("#dates a").click(function() { y = $(this).attr("href"); load(y); return false; }); } mod(); </script> The actual AJAX works like a charm. My problem lies with the response to the request. Because it is a French website, there are many accented letters. I'm using the ISO-8859-15 charset for that very reason. However, in the response to my AJAX request, the accents are becoming ?'s because the character encoding seems to be changed back to UTF-8. How do I avoid this? I've already tried adding some PHP at the top of the requested documents to set the character set: <?php header('Content-Type: text/html; charset=ISO-8859-15'); ?> But that doesn't seem to work either. Any thoughts? Also, while any of you are looking here...why does the rightmost column seem to become smaller when a new page is loaded, causing the table to distort and each <li> within the <td> to wrap to the next line? Cheers

• UniqueConstraint in EmbeddedConfiguration

  I just started using db4o on C#, and I'm having trouble setting the UniqueConstraint on the DB.. here's the db4o configuration static IObjectContainer db = Db4oEmbedded.OpenFile(dbase.Configuration(), "data.db4o"); static IEmbeddedConfiguration Configuration() { IEmbeddedConfiguration dbConfig = Db4oEmbedded.NewConfiguration(); // Initialize Replication dbConfig.File.GenerateUUIDs = ConfigScope.Globally; dbConfig.File.GenerateVersionNumbers = ConfigScope.Globally; // Initialize Indexes dbConfig.Common.ObjectClass(typeof(DAObs.Environment)).ObjectField("Key").Indexed(true); dbConfig.Common.Add(new Db4objects.Db4o.Constraints.UniqueFieldValueConstraint(typeof(DAObs.Environment), "Key")); return dbConfig; } and the object to serialize: class Environment { public string Key { get; set; } public string Value { get; set; } } everytime I get to commiting some values, an "Object reference not set to an instance of an object." Exception pops up, with a stack trace pointing to the UniqueFieldValueConstraint. Also, when I comment out the two lines after the "Initialize Indexes" comment, everything runs fine (Except you can save non-unique keys, which is a problem)~ Commit code (In case I'm doing something wrong in this part too:) public static void Create(string key, string value) { try { db.Store(new DAObs.Environment() { Key = key, Value = value }); db.Commit(); } catch (Db4objects.Db4o.Events.EventException ex) { System.Console.WriteLine (DateTime.Now + " :: Environment.Create\n" + ex.InnerException.Message +"\n" + ex.InnerException.StackTrace); db.Rollback(); } } Help please?

• Informix, NHibernate, TransactionScope interaction difficulties

  - by John Prideaux

  I have a small program that is trying to wrap an NHibernate insert into an Informix database in a TransactionScope object using the Informix .NET Provider. I am getting the error specified below. The code without the TransactionScope object works -- including when the insert is wrapped in an NHibernate session transaction. Any ideas on what the problem is? BTW, without the EnterpriseServicesInterop, the Informix .NET Provider will not participate in a TransactionScope transaction (verified without NHibernate involved). Code Snippet: public static void TestTScope() { Employee johnp = new Employee { name = "John Prideaux" }; using (TransactionScope tscope = new TransactionScope( TransactionScopeOption.Required, new TransactionOptions() { Timeout = new TimeSpan(0, 1, 0), IsolationLevel = IsolationLevel.ReadCommitted }, EnterpriseServicesInteropOption.Full)) { using (ISession session = OpenSession()) { session.Save(johnp); Console.WriteLine("Saved John to the database"); } } Console.WriteLine("Transaction should be rolled back"); } static ISession OpenSession() { if (factory == null) { Configuration c = new Configuration(); c.AddAssembly(Assembly.GetCallingAssembly()); factory = c.BuildSessionFactory(); } return factory.OpenSession(); } static ISessionFactory factory; Stack Trace: NHibernate.ADOException was unhandled Message="Could not close IBM.Data.Informix.IfxConnection connection" Source="NHibernate" StackTrace: at NHibernate.Connection.ConnectionProvider.CloseConnection(IDbConnection conn) at NHibernate.Connection.DriverConnectionProvider.CloseConnection(IDbConnection conn) at NHibernate.Tool.hbm2ddl.SuppliedConnectionProviderConnectionHelper.Release() at NHibernate.Tool.hbm2ddl.SchemaMetadataUpdater.GetReservedWords(Dialect dialect, IConnectionHelper connectionHelper) at NHibernate.Tool.hbm2ddl.SchemaMetadataUpdater.Update(ISessionFactory sessionFactory) at NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg, IMapping mapping, Settings settings, EventListeners listeners) at NHibernate.Cfg.Configuration.BuildSessionFactory() at HelloNHibernate.Employee.OpenSession() in D:\Development\ScratchProject\HelloNHibernate\Employee.cs:line 73 at HelloNHibernate.Employee.TestTScope() in D:\Development\ScratchProject\HelloNHibernate\Employee.cs:line 53 at HelloNHibernate.Program.Main(String[] args) in D:\Development\ScratchProject\HelloNHibernate\Program.cs:line 19 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: IBM.Data.Informix.IfxException Message="ERROR - no error information available" Source="IBM.Data.Informix" ErrorCode=-2147467259 StackTrace: at IBM.Data.Informix.IfxConnection.HandleError(IntPtr hHandle, SQL_HANDLE hType, RETCODE retcode) at IBM.Data.Informix.IfxConnection.DisposeClose() at IBM.Data.Informix.IfxConnection.Close() at NHibernate.Connection.ConnectionProvider.CloseConnection(IDbConnection conn) InnerException:

• How do I encapsulate form/post/validation[/redirect] in ViewUserControl in ASP.Net MVC 2

  - by paul

  What I am trying to achieve: encapsulate a Login (or any) Form to be reused across site post to self when Login/validation fails, show original page with Validation Summary (some might argue to just post to Login Page and show Validation Summary there; if what I'm trying to achieve isn't possible, I will just go that route) when Login succeeds, redirect to /App/Home/Index also, want to: stick to PRG principles avoid ajax keep Login Form (UserController.Login()) as encapsulated as possible; avoid having to implement HomeController.Login() since the Login Form might appear elsewhere All but the redirect works. My approach thus far has been: Home/Index includes Login Form: <%Html.RenderAction("Login","User");%> User/Login ViewUserControl<UserLoginViewModel> includes: <%=Html.ValidationSummary("") % using(Html.BeginForm()){} includes hidden form field "userlogin"="1" public class UserController : BaseController { ... [AcceptPostWhenFieldExists(FieldName = "userlogin")] public ActionResult Login(UserLoginViewModel model, FormCollection form){ if (ModelState.IsValid) { if(checkUserCredentials()) { setUserCredentials() return this.RedirectToAction<Areas.App.Controllers.HomeController>(x = x.Index()); } else { return View(); } } ... } Works great when: ModelState or User Credentials fail -- return View() does yield to Home/Index and displays appropriate validation summary. (I have a Register Form on the same page, using the same structure. Each form's validation summary only shows when that form is submitted.) Fails when: ModelState and User Credentials valid -- RedirectToAction<>() gives following error: "Child actions are not allowed to perform redirect actions." It seems like in the Classic ASP days, this would've been solved with Response.Buffer=True. Is there an equivalent setting or workaround now? Btw, running: ASP.Net 4, MVC 2, VS 2010, Dev/Debugging Web Server I hope all of that makes sense. So, what are my options? Or where am I going wrong in my approach? tia!

• Warning: Memcache::connect(0memcache.connect0): Can't connect to localhost:11211, Connection refuse

  - by Stick it to THE MAN

  I am using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10. I am incorporating memcache to the website. I have modified the setup() method in apps/frontend/ProjectConfiguration.class.php like this: class ProjectConfiguration { public function setup() { // original SF generated code here .. require_one sfConfig::get('sf_lib_dir').'/MyCache.class.php'; myCache::init(); } } my cache singleton is implemented something like this: class MyCache { private static memcache = null; private static inited = false; public static init() { if (self::$inited) return; self::$memcache = new Memcache(); if (self::$memcache->connect('localhost', 11211) { // Do some stuff .. self::$inited = true; } } } Warning: Memcache::connect(0memcache.connect0): Can't connect to localhost:11211, Connection refused(111) in /path_to_class/MyCache.class.php This happens for both CLI (e.g. running SF tasks) or for web access through the browser. Does anyone know how to resolve this (I suspect its something to do with Linux user privileges). As an aside, I am aware that SF prvoides an sfAPCache wrapper class for cacheing. I am intentionally not using it for two reasons: I cannot find any comprehensive (and up to date) docs on this class I want to learn the memcache API directly, since I will be accesing it from other languages.

• ClickOnce Deployment Error - Access to the Path is Denied

  - by michael.lukatchik

  I have a WPF app that I'm deploying to a network path using ClickOnce deployment. After the app is deployed to a network location, I use the ClickOnce html page to launch the installation process. I am successfully able to download and install the app. However, my users are not able to download and install the app. When a user navigates to the ClickOnce html page and clicks to begin the installation process, the following error message is received: ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. * Activation of http://software.mycompany.com/myapp/myapp.application resulted in exception. Following failure messages were detected: + Downloading file://dev/webs/software/myapp/myapp.application did not succeed. * [4/5/2010 1:56:59 PM] System.Deployment.Application.DeploymentDownloadException (Unknown subtype) - Downloading file://dev/Webs/software/myapp/myapp.application did not succeed. All signs point to this being a security issue. So, I've done the following: Ensured that "Everyone" had read access to the files that were being deployed as part of my project Ensured that "Everyone" had read access to the network location where the app was deployed (//dev/webs/software/myapp) Ensured that "Everyone" had read access to the IIS path where the ClickOnce html page is located In each of these cases, I've made no progress in getting the app to successfully deploy via ClickOnce. Again, the odd thing is that I am able to successfully walk through the process of downloading and installing the app. It's my users, though, that need the ability to download and install the app. I've looked extensively on the web for answers, but there hasn't been much. I'd like to resolve the issue without "re-installing" or "rigging" anything. I need a solid answer. Thank you all for your input!! Mike

Now, I know why I am getting the 503 error. W3C explained it very clearly. But I still want to validate the document.

• onmouseover with django / imagekit

  - by Michael Moreno

  I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

• IE and absolute positioning divs

  - by kainaw

  This problem is only in IE. Consider the following HTML: <html> <body> <div style='position:absolute;left:1em;right:1em;top:1em;bottom:1em;overflow:auto;'> Put more than a full screen of text in here. It should create a scroll inside the div. In IE, it stretches the div out vertically. </div> </body> </html> If you put a ton of text in the div, IE will stretch the div out beyond the declared "bottom". I know what it is doing. It considers the bottom of the page to be the bottom of the page after all of the text has been rendered. I want bottom to be the bottom of the visible window. So, I want to have a div that is centered inside the window. Is there some retarded hack to make IE comprehend the basic concept of CSS?

• Unmanaged DLL in C# Web Service

  - by Telis

  Hi Guys, please help µe as I am new into accessing an unmanaged DLL from C#.. I have a large unmanaged DLL in C++ and I am trying to access the DLL's classes and functions from a C# Web Service. I have seen many examples how to use DLLImport, but for some reason I am stuck with my very first wrapper method spending many hours with no luck.. What should I do to return an object in my 'Marshaled' [DllImport..] function? I would like to do something like that: [DllImport("unmanaged.dll")] public static extern MyClass MyFunction(); Here is the definition of my C++ class and the function that I want to access: class __declspec(dllexport) TPDate { public: TPDate(); TPDate(const TPDate& rhs); ... //today's date. static TPDate AsOfDate(void); ... } In my Web service I have declared the following StructLayout: [StructLayout(LayoutKind.Sequential)] public class TPDate { public TPDate(TPDate d) { _tpDate = d; } public TPDate _tpDate; } and here's where I think that I'm not doing something right: class WrapperTPDate { [DllImport("TPTools.dll", ExactSpelling=false, EntryPoint = "?AsOfDate@TPDate@@SA?AV1@XZ", CallingConvention = CallingConvention.StdCall)] [return: MarshalAs(UnmanagedType.Struct)] **public static extern TPDate AsOfDate();**// HERE THERE IS PROBLEM }; I am calling the wrapper as follows from my WebMethod: [WebMethod] public void ConstructModel() { TPDate date1 = WrapperTPDate.AsOfDate();// Here I get exception TPDate date = new TPDate(date1); } The exception i am getting is: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Runtime.InteropServices.MarshalDirectiveException: Cannot marshal 'return value': Invalid managed/unmanaged type combination (this type must be paired with LPStruct or Interface). If I change it to LPSTRUCT, I am getting another exception: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt Could you please tell me where I'm doing wrong here Thanks

• Error with masterpage

  - by Raphyboy

  Hi, i'm creating a brand new masterpage with VS2010 Beta 2 and I get this warning (that causes me errors in the content pages): Validation (XHTML 1.0 Transitional): Content is not supported outside 'script' or 'asp:content' regions. The masterpage's code : <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Bob.master.cs" Inherits="TShirtFactory.Web.All.Core.lib.masterpage.Bob" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <asp:ContentPlaceHolder ID="head" runat="server"> </asp:ContentPlaceHolder> </head> <body> <form id="form1" runat="server"> <div> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </form> </body> </html> As you can see, it's the default masterpage generated code. I get the warning when I hover the tag at top. Does anybody have an idea of what's going on ? Thank you

• How to add an image when generating a pdf-file with javascript. When adding the imageLoadFromURL no pdf is generated

  - by Angu Handschuh

  I've got a problem with adding an image when generating a pdf-file with javascript. Here is my code: <!DOCTYPE html> <html> <head> <script type="text/javascript" src="base64.js"></script> <script type="text/javascript" src="sprintf.js"></script> <script type="text/javascript" src="jspdf.js"></script> <script> function demo1() { var name = prompt('Name: '); var nachname=prompt('Nachname: '); var doc = new jsPDF(); doc.setFontSize(22); doc.text(20, 20, 'Der eingegebene Text'); doc.setFontSize(16); doc.imageLoadFromUrl('image.jpg'); doc.imagePlace(20, 40); doc.text(20, 30, 'Name: ' + name); doc.text(20,40,'Nachname:'+nachname); // Output as Data URI doc.output('datauri'); } </script> </head> <body> <h2> Ein Document </h2> <a href="javascript:demo1()"> PDF erstellen </a> </body> </html> Before adding doc.imageLoadFromUrl('image.jpg'); doc.imagePlace(20, 40); the code runs without picture. It starts with a demand note for the name and the second name, after this it generates a pdf-file. But when adding the imageLoad-Method there is no pdf-file generated. Does anyone konws how to solve this problem?

• Wrapped WPF Control

  - by Robert

  Hi, I'm trying to create a GUI (WPF) Library where each (custom) control basically wraps an internal (third party) control. Then, I'm manually exposing each property (not all of them, but almost). In XAML the resulting control is pretty straightforward: <my:CustomButton Content="ClickMe" /> And the code behind is quite simple as well: public class CustomButton : Control { private MyThirdPartyButton _button = null; static CustomButton() { DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomButton), new FrameworkPropertyMetadata(typeof(CustomButton))); } public CustomButton() { _button = new MyThirdPartyButton(); this.AddVisualChild(_button); } protected override int VisualChildrenCount { get { return _button == null ? 0 : 1; } } protected override Visual GetVisualChild(int index) { if (_button == null) { throw new ArgumentOutOfRangeException(); } return _button; } #region Property: Content public Object Content { get { return GetValue(ContentProperty); } set { SetValue(ContentProperty, value); } } public static readonly DependencyProperty ContentProperty = DependencyProperty.Register( "Content", typeof(Object), typeof(CustomButton), new FrameworkPropertyMetadata(new PropertyChangedCallback(ChangeContent)) ); private static void ChangeContent(DependencyObject source, DependencyPropertyChangedEventArgs e) { (source as CustomButton).UpdateContent(e.NewValue); } private void UpdateContent(Object sel) { _button.Content = sel; } #endregion } The problem comes after we expose MyThirdPartyButton as a property (in case we don't expose something, we would like to give the programmer the means to use it directly). By simply creating the property, like this: public MyThirdPartyButton InternalControl { get { return _button; } set { if (_button != value) { this.RemoveVisualChild(_button); _button = value; this.AddVisualChild(_button); } } } The resulting XAML would be this: <my:CustomButton> <my:CustomButton.InternalControl> <thirdparty:MyThirdPartyButton Content="ClickMe" /> </my:CustomButton.InternalControl> And what I'm looking for, is something like this: <my:CustomButton> <my:CustomButton.InternalControl Content="ClickMe" /> But (with the code I have) its impossible to add attributes to InternalControl... Any ideas/suggestions? Thanks a lot, -- Robert

• The ViewData item that has the key 'MY KEY' is of type 'System.String' but must be of type 'IEnumerable<SelectListItem>'.

  - by JBibbs

  I am trying to populate a dropdown list from a database mapped with Linq 2 SQL, using ASP.NET MVC 2, and keep getting this error. I am so confused because I am declaring a variable with the type IEnumerable<SelectListItem> on the second line, but the error makes me think this is not the case. I feel like this should be very simple, but I am struggling. Any help is appreciated. Here are the interesting bits of my controller: public ActionResult Create() { var db = new DB(); IEnumerable<SelectListItem> basetypes = db.Basetypes.Select(b => new SelectListItem { Value = b.basetype, Text = b.basetype }); ViewData["basetype"] = basetypes; return View(); } And here are the interesting bits of my view: <div class="editor-label"> <%: Html.LabelFor(model => model.basetype) %> </div> <div class="editor-field"> <%: Html.DropDownList("basetype") %> <%: Html.ValidationMessageFor(model => model.basetype) %> </div> Here is the Post action when submitting the Form // POST: /Meals/Create [HttpPost] public ActionResult Create(Meal meal) { if (ModelState.IsValid) { try { // TODO: Add insert logic here var db = new DB(); db.Meals.InsertOnSubmit(meal); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(meal); } } else { return View(meal); } } Thanks.
