  • ASP.NET MVC Class level custom data-annotation and ModelState keys

    - by Neil
    Hi, I have custom class level validation attribute, inheriting from ValidationAttribute, on my model. How come it doesn't register a key in the ModelState when its IsValid is false? I can see the the error message in the ModelState.Values collection, but the ModelState.Keys collection only shows an empty string "". Can I provide a key for it - presumably this is because its not assigned to a property? I wanna be able to use ModelState.Remove in my controller to remove this error upon a certain condition, but I have no Key! Any ideas?

  • VB .NET DirectCast and Type Reflection

    - by msarchet
    The application that I am working on has a generic Parent Form called RSChild, that is used to perform some operations depending on whether or not the control that is contained within it is in a MdiTabManager or inside of its own modal form. Then the actual User Controls contained within Inherit from a Interface Called ObjectEdit (Objects that we allow to be edited). At a point in my code I am doing this. Public Function doesTabExist(ByVal id As Integer, ByVal recordType As Enums.eRecordType) As Boolean Dim alikePages As Object = (From tabs In DirectCast(Control.FromHandle(MainForm.SharedHandle), MainForm).XtraTabbedMdiManager1.Pages Where DirectCast(tabs.MdiChild, RSChild).RSObject.RecordType = recordType Select tabs) For Each page As DevExpress.XtraTabbedMdi.XtraMdiTabPage In alikePages Select Case recordType Case Enums.eRecordType.Doctor If id = DirectCast(castTabPageToRSChild(page).RSObject, UI.Doctor).ID Then pageToActive(page) Return True End If 'rest of the cases so the case block is repeated 10 times' End Function And my castTabPageToRSChild(page) is a lambda function as Such Dim castTabPageToRSChild As Func(Of DevExpress.XtraTabbedMdi.XtraMdiTabPage, RSChild) = Function(page) DirectCast(page.MdiChild, RSChild) So my Question is, I have about 10 case statements, all because I can't seem to find a way to use reflection to get the underlying Type of the RSObject Object. So I have the whole If block repeated over and over. I tried doing castTabPageToRSChild(page)RSObject.GetType and using that in the DirectCast and I also tried creating another object that was separate from that and doing the same thing. My code works as intended I'm just trying to see if there is a manner in which I didn't have a lot of replicated code. My vision would be to do something like For Each page As XtraMdiTabPage In alikePages If id = DirectCast(castTabPageToRSchild(page).RSObject, TypeOfThatObject).Id Then Return True Next However I have a feeling this is not possible due to the behavior of DirectCast.

  • ASP.NET MVC: routing help

    - by pcampbell
    Consider two methods on the controller CustomerController.cs: //URL to be http://mysite/Customer/ public ActionResult Index() { return View("ListCustomers"); } //URL to be http://mysite/Customer/8 public ActionResult View(int id) { return View("ViewCustomer"); } How would you setup your routes to accommodate this requirement? How would you use Html.ActionLink when creating a link to the View page?

  • ASP.NET MVC 2 - ViewModel Prefix

    - by Cosmo
    I want to use RenderPartial twice in my view with different models associated. The problem is that some properties are present in both models (nickname, password). They have no prefix, so even the id's or names are equal in the output. Now, if I have model errors for nickname or password, both fields get highlighted. Main View: <div> <% Html.RenderPartial("Register", Model.RegisterModel); %> </div> <div> <% Html.RenderPartial("Login", Model.LoginModel); %> </div> Login PartialView: <% using (Html.BeginForm("Login", "Member")) { %> <fieldset> <legend>Login</legend> <p> <%= Html.LabelFor(x => x.Nickname) %> <%= Html.TextBoxFor(x => x.Nickname) %> </p> <p> <%= Html.LabelFor(x => x.Password) %> <%= Html.PasswordFor(x => x.Password) %> </p> <input type="submit" value="Login" /> </fieldset> <% } % Register PartialView: <% using (Html.BeginForm("Register", "Member")) { %> <fieldset> <legend>Register</legend> <p> <%= Html.LabelFor(x => x.Nickname) %> <%= Html.TextBoxFor(x => x.Nickname) %> </p> <p> <%= Html.LabelFor(x => x.Email) %> <%= Html.TextBoxFor(x => x.Email) %> </p> <p> <%= Html.LabelFor(x => x.Password) %> <%= Html.PasswordFor(x => x.Password) %> </p> <p> <%= Html.LabelFor(x => x.PasswordRepeat) %> <%= Html.PasswordFor(x => x.PasswordRepeat) %> </p> <input type="submit" value="Register" /> </fieldset> <% } % How can I change this?

  • Why aren't we programming on the GPU???

    - by Chris
    So I finally took the time to learn CUDA and get it installed and configured on my computer and I have to say, I'm quite impressed! Here's how it does rendering the Mandelbrot set at 1280 x 678 pixels on my home PC with a Q6600 and a GeForce 8800GTS (max of 1000 iterations): Maxing out all 4 CPU cores with OpenMP: 2.23 fps Running the same algorithm on my GPU: 104.7 fps And here's how fast I got it to render the whole set at 8192 x 8192 with a max of 1000 iterations: Serial implemetation on my home PC: 81.2 seconds All 4 CPU cores on my home PC (OpenMP): 24.5 seconds 32 processors on my school's super computer (MPI with master-worker): 1.92 seconds My home GPU (CUDA): 0.310 seconds 4 GPUs on my school's super computer (CUDA with static domain decomposition): 0.0547 seconds So here's my question - if we can get such huge speedups by programming the GPU instead of the CPU, why is nobody doing it??? I can think of so many things we could speed up like this, and yet I don't know of many commercial apps that are actually doing it. Also, what kinds of other speedups have you seen by offloading your computations to the GPU?

  • Standard way to persist data between requests in ASP.NET-MVC

    - by Nate Bross
    What is the most standard or best way to persist data between requests? Should I use cookies or session variables? I'm interested in keeping data like sort order, sort column, and page number (for paginiation). I'm coming from a webforms background so normally this type of thing was automatically handled for me in the viewstate of the controls I was using.

  • Unexpected result in .NET 4 DirectoryInfo.EnumerateFiles(string)

    - by xkingpin
    It seems that the following code is not working as expected. I would assume that the following call to EnumarateFiles would only return files that match the filename pattern of c* ... however, filenames with H* are still getting returned. For example... the following file will get deleted in the following code (HNNN09060900932.xml). What's the issue? This is a major bug in my application. string searchPattern = "C*"; // get each file in this directory that is less than a given date var files = from file in SubDir.EnumerateFiles(searchPattern) where file.LastWriteTime < KeepDate select file; foreach (var file in files) { file.Delete(); }

  • How to extract the 256x256 icon from an icon and display it in .Net, Winforms, XP

    - by Jules
    Here's the code that I use to extract the icon size that I want: Dim i As Icon = My.Resources.Spectrum Using i2 As New Icon(i, New Size(256, 256)) Me.PictureBox1.Image = i2.ToBitmap End Using This works from 16x16 up to 128x128 but for 256x256 it extracts the 128x128 icon. I tried 0x0, because I seem to remember that that is how the large size is stored in the meta data, but that didn't work either.

  • ASP.NET MVC Route Default values

    - by Sadegh
    hi, i defined two routes in global.asax like below context.MapRoute("HomeRedirect", "", new { controller = "Home", action = "redirect" }); context.MapRoute("UrlResolver", "{culture}/some", new { culture = "en-gb", controller = "someController", action = "someAction" }, new { culture = new CultureRouteConstraint() }); according to above definition, when user request mysite.com/ redirect action of HomeController should be called and in that: public class HomeController : Controller { public ActionResult Redirect() { return RedirectToRoute("UrlResolver"); } } i want to redirect user to second defined route on above, so also i specified default values for that and some Constraint for each of those. but when RedirectToRoute("UrlResolver") turns, no default values passed to routeConstraints on second route and No route in the route table matches the supplied values shows. update my CultureRouteConstraint: public class CultureRouteConstraint : IRouteConstraint { bool IRouteConstraint.Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { try { var parameter = values[parameterName] as string; return (someCondition(parameter)); } catch { return false; } } } now values parameter haven't culture key/value, but route parameter have that.

  • Pair programming tools that are not remote

    - by JonathanTech
    I am currently in a job where we practice serious pair programming on windows machines. We both have a set of keyboards, mice, and we have two monitors, which works well for switching who's the driver really easy, but there are some points in the session that I would like to start writing tests at the same time that my pair is writing implementation. I am wondering if there is any program that would allow me to have effectively two cursors and keyboard focuses on the same computer. If they don't exist then I am willing to experiment with my own solution, but I would like input as to how to best accomplish this. I am most familiar with .Net 3.5 technologies, but I also know Java and am willing to learn C++ to solve this problem. If I was creating the solution myself I would go down the road of being able to grab the input of one hardware device (i.e. a specific mouse that's installed) and prevent Windows from moving the pointer, and instead move my own programs pointer independently.

  • File extensions and MIME Types in .NET

    - by Marc Climent
    I want to get a MIME Content-Type from a given extension (preferably without accessing the physical file). I have seen some questions about this and the methods described to perform this can be resumed in: Use registry information. Use urlmon.dll's FindMimeFromData. Use IIS information. Roll your own MIME mapping function. Based on this table, for example. I've been using no.1 for some time but I realized that the information provided by the registry is not consistent and depends on the software installed on the machine. Some extensions, like .zip don't use to have a Content-Type specified. Solution no.2 forces me to have the file on disk in order to read the first bytes, which is something slow but may get good results. The third method is based on Directory Services and all that stuff, which is something I don't like much because I have to add COM references and I'm not sure it's consistent between IIS6 and IIS7. Also, I don't know the performance of this method. Finally, I didn't want to use my own table but at the end seems the best option if I want a decent performance and consistency of the results between platforms (even Mono). Do you think there's a better option than using my own table or one of other described methods are better? What's your experience?

  • ASP.NET User Control Value

    - by Steven
    I created a DatePicker user control (ASP code below, no code behind) which is simply a textbox, image button, and a sometimes visible calendar. <%@ Control Language="vb" AutoEventWireup="false" _ CodeBehind="myDatePicker.ascx.vb" Inherits="Website.myDate" %> <%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" _ tagprefix="asp" %> <asp:TextBox ID="Date1" runat="server"></asp:TextBox> <asp:Image ID="Image1" runat="server" ImageUrl="~/Calendar_scheduleHS.png" /> <asp:CalendarExtender ID="Date1_CalendarExtender" runat="server" Enabled="True" TargetControlID="Date1" PopupButtonID="Image1" > </asp:CalendarExtender> Can I somehow tie or pass the value of the TextBox as the value of the whole control to use in the calling code?

  • ASP.Net MVC Keeping action parameters between postbacks

    - by Matt
    Say I have a page that display search results. I search for stackoverflow and it returns 5000 results, 10 per page. Now I find myself doing this when building links on that page: <%=Html.ActionLink("Page 1", "Search", new { query=ViewData["query"], page etc..%> <%=Html.ActionLink("Page 2", "Search", new { query=ViewData["query"], page etc..%> <%=Html.ActionLink("Page 3", "Search", new { query=ViewData["query"], page etc..%> <%=Html.ActionLink("Next", "Search", new { query=ViewData["query"], page etc..%> I dont like this, I have to build my links with careful consideration to what was posted previously etc.. What I'd like to do is <%=Html.BuildActionLinkUsingCurrentActionPostData ("Next", "Search", new { Page = 1}); where the anonymous dictionary overrides anything currently set by previous action. Essentially I care about what the previous action parameters were, because I want to reuse, it sounds simple, but start adding sort and loads of advance search options and it starts getting messy. Im probably missing something obvious

  • Using dynamic parameters in email publisher subjectSettings block with CruiseControl.Net

    - by Joe
    I am trying to get dynamic parameters to be used in the email publisher's subjectSettings block. For example, <project> ... <parameters> <textParameter> <name>version</name> <display>Version to install</display> <description>The version to install.</description> <required>true</required> </textParameter> </parameters> <tasks> ... </tasks> <publishers> .... <email includeDetails="TRUE"> <from>buildmaster</from> <mailhost>localhost</mailhost> <users> <user name="Joe" group="buildmaster" address="jdavies" /> </users> <groups> <group name="buildmaster"> <notifications> <notificationType>Always</notificationType> </notifications> </group> <group name="users"> <notifications> <notificationType>Success</notificationType> <notificationType>Fixed</notificationType> </notifications> </group> </groups> <subjectSettings> <subject buildResult="Success" value="Version ${version} installed." /> <subject buildResult="Fixed" value="Version ${version} fixed and installed." /> </subjectSettings> <modifierNotificationTypes> <notificationType>Success</notificationType> </modifierNotificationTypes> </email> </project> I have tried using ${version} and $[version]. When I use $[version], the entire subject line is empty! Are dynamic parameters supported in this case, and if so, what am I doing wrong?

  • ASP.NET MVC 2 RTM - favicon not displayed in Internet Explorer

In Firefox and Safari the favicon works fine. I have even tried to replace href with the URL to my website (http://www......./Content/Images/favicon.ico) but that still does not work in Internet Explorer. Am I missing something?

  • .NET custom property attribute?

    - by ropstah
    EDIT: I'd better rephrase: How can I shift the GET-implementation of a Class property to a / using a custom attribute? (I've added instantation vars (classname, propertyname) to the attribute, however I'd rather have these automatically fetched ofcourse.) Public Class CustomClass <CustomAttributeClass(ClassName:="CustomClass", PropertyName = "SomeProperty")> _ Public Property SomeProperty() as String Get() as String //This implementation should be handled by the attribute class End Get Set(Byval value as String) Me._someProperty = value End Set End Property End Class Old question: I want to create a custom property attribute for classes. I can create a class derived from Attribute, and 'mark' the property with the attribute, but where to go from here? I have a repository where I can quickly get data based on the attributes values. I would like to generalize the behaviour of the property in the attribute but I don't know how to go from here... Any help would be greatly accepted! Public Class CustomDataAttribute : Inherits Attribute Private _name As String Public Sub New(ByVal name As String) Me.Name = name End Sub Property Name() As String Get Return _name End Get Set(ByVal value As String) Me._name = value End Set End Property End Class Public Class CustomClass <CustomDataAttribute(Name:="CustomField")> _ Public Property CustomField() End Property End Class

  • ASP.NET MVC 2 Post AJAX from from JavaScript

    - by ANDyW
    Hi, I got control with strongly typed View, with Ajax.BeginForm(). Now I would like to change submit method from <input type="submit" id="testClick" value="Submit" /> To some javascript method DoSubmit(). What I tried is : Invoke click on that submit button Invoke submit on form ('form1').submit(), document.forms['form1'].submit() jQuery forms with ('form1').AjaxSubmit(); Create jQuery AJAX $.ajax({ type: "POST", url: $("#form1").attr("action"), data: $("#form1").serialize(), success: function() { alert("epic win!!!1!1!") }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert("epic fail!") } }); All those method created normal request (not AJAX), or they didn't work. So anyone know how I can do AJAX submit "Form", from JavaScript and strongly typed mechanism (public AcrionResult MyFormAction(FormModel model); ) will work?
