  • ASP.NET MVC 2: Linq to SQL entity w/ ForeignKey relationship and Default ModelBinder strangeness

    - by Simon
    Once again I'm having trouble with Linq to Sql and the MVC Model Binder. I have Linq to Sql generated classes, to illustrate them they look similar to this: public class Client { public int ClientID { get; set; } public string Name { get; set; } } public class Site { public int SiteID { get; set; } public string Name { get; set; } } public class User { public int UserID { get; set; } public string Name { get; set; } public int? ClientID { get; set; } public EntityRef<Client> Client { get; set; } public int? SiteID { get; set; } public EntityRef<Site> Site { get; set; } } The 'User' has a relationship with the 'Client' and 'Site . The User class has nullable ClientIDs and SiteIDs because the admin users are not bound to a Client or Site. Now I have a view where a user can edit a 'User' object, the view has fields for all the 'User' properties. When the form is submitted, the appropiate 'Save' action is called in my UserController: public ActionResult Save(User user, FormCollection form) { //form['SiteID'] == 1 //user.SiteID == 1 //form['ClientID'] == 1 //user.ClientID == null } The problem here is that the ClientID is never set, it is always null, even though the value is in the FormCollection. To figure out whats going wrong I set breakpoints for the ClientID and SiteID getters and setters in the Linq to Sql designer generated classes. I noticed the following: SiteID is being set, then ClientID is being set, but then the Client EntityRef property is being set with a null value which in turn is setting the ClientID to null too! I don't know why and what is trying to set the Client property, because the Site property setter is never beeing called, only the Client setter is being called. Manually setting the ClientID from the FormCollection like this: user.ClientID = int.Parse(form["ClientID"].ToString()); throws a 'ForeignKeyReferenceAlreadyHasValueException', because it was already set to null before. The only workaround I have found is to extend the generated partial User class with a custom method: Client = default(EntityRef<Client>) but this is not a satisfying solution. I don't think it should work like this? Please enlighten me someone. So far Linq to Sql is driving me crazy! Best regards

  • If you were developing shareware softwares for windows, would you target the .Net Framework or use n

    - by bohoo
    For the sake of the question, by 'shareware' I mean a software which is relatively small in size (up to few dozens of mb) and available for download and evaluation through a web site. I'm asking this question, because I don't understand something regarding the current state of windows commercial desktop development. It seems to me that: There is no reliable statistic regarding the extent of windows systems with .Net Framework installed. It makes no sense to force the end user to install the 20-60mb .Net for an application which may be smaller. Applications conforms to the term 'shareware' above have a big share on the win os market. Much of them don't need the capabilities of low level languages like c++, and therefore ideally they should be developed with a RAD enviroment. So, One would suppose there will be a blossom of RAD enviroments for native win code. But I know about only one - Delphi, and Delphi is so unpopular. How is that?

    Scenario: I'm just trying to update my database with the changes made by the user to their information.

There are no errors, everything compiles correctly, but nothing happens. The record remains unchanged.

  • .NET MVC Code Generation

    - by Josh
    Is there a way to force the MVC automatically generated code to follow the conventions you have set in your preferences? For example, I keep all curly braces on the same lines as their declaring class, method, etc, but when generating a controller, it completely disregards my settings. Is there a setting someplace to force the same code generation as other parts of project?

  • ASP.NET MVC submitting json array to controller as regular post request (nonajax)

    - by j3ko
    All the examples of json I can find online only show how to submit json arrays w/ the jquery command $.ajax(). I'm submitting some data from a custom user control as a json array. I was wondering if it's possible to submit a json array as a regular post request to the server (like a normal form) so the browser renders the page returned. Controller: [JsonFilter(Param = "record", JsonDataType = typeof(TitleViewModel))] public ActionResult SaveTitle(TitleViewModel record) { // save the title. return RedirectToAction("Index", new { titleId = tid }); } Javascript: function SaveTitle() { var titledata = GetData(); $.ajax({ url: "/Listing/SaveTitle", type: "POST", data: titledata, contentType: "application/json; charset=utf-8", }); } Which is called from a save button. Everything works fine but the browser stays on the page after submitting. I was thinking of returning some kind of custom xml from the server and do javascript redirect but it seems like a very hacky way of doing things. Any help would be greatly appreciated.

    - by Chev
    I cannot get the following route to fire when a url is requested from a script tag.

  • VB.NET template instance - passing a variable data type

    - by FerretallicA
    As the title suggests, I'm tyring to pass a variable data type to a template class. Something like this: frmExample = New LookupForm(Of Models.MyClass) 'Works fine Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine repoGeneric = New Repositories.Repository(Of SelectedType) 'Ba-bow! repoGeneric = New Repositories.Repository(Of InstanceOfMyClass.GetType()) 'Ba-bow! I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either. (How) can I create an instance of a dynamically typed repository at runtime?

New contacts are added by pressing an appropriate button and they appear as an entry in the list on the form. I try now to add an edit button that will edit existing entries. User will select a given entry on the list and press edit button and will be presented with an appropriate form (AddContFrm). Right now it simply adds another entry with the same title. Logic is handled in a class called Contact.vb Here is my code. Public Class Contact Public Contact As String Public Title As String Public Fname As String Public Surname As String Public Address As String Private myCont As String Public Property Cont() Get Return myCont End Get Set(ByVal value) myCont = Value End Set End Property Public Overrides Function ToString() As String Return Me.Cont End Function Sub NewContact() FName = frmAddCont.txtFName.ToString frmStart.lstContact.Items.Add(FName) frmAddCont.Hide() End Sub Public Sub Display() Dim C As New Contact 'C.Cont = InputBox("Enter a title for this contact.")
