model-binding

All, I have a grid view that has the following columns. The paging work great, but not sorting. Everytime I click on the Category column to sort by category I would get this error: Instance property 'Category.CategoryName' is not defined for type 'ESA.Data.Models.Entity.Project' This error statement is not true because the gridview was able to display the column correctly. Here is the select method public IQueryable<Project> getProjects() { ApplicationServices objServices = new ApplicationServices(); IQueryable<Project> lstProject; lstProject = objServices.getProjects(); return lstProject; }

I have the following action signature [ValidateInput(false)] public HttpResponseMessage PostParam(Param param) With Param looking something like this: public class Param { public int Id { get; set;} public string Name { get; set; } public string Choices { get; set; } } Here's the hitch - what comes over the wire is something like this { Id: 2, Name: "blah", Choices: [ { foo: "bar" }, { blah: "blo" something: 123 } ] } I don't want "Choices" to deserialize - I want it stored as a string (yes, I understand the security implications). Understandably, I get an error because since the default

What is the best way to trim all the properties of the model passed to the MVC web api (post method with complex object). One thing simply can be done is calling Trim function in the getter of all the properties. But, I really do not like that. I want the simple way something like the one mentioned for the MVC here ASP.NET MVC: Best way to trim strings after data entry. Should I create a custom model binder? To trim all incoming string values in Web API, you can define a Newtonsoft.Json.JsonConverter : class TrimmingConverter : JsonConverter { public override bool CanConvert(Type objectType) {

This is a brain-cracking experience with JTable binding. Here's what I did. I created a JTable with columns set to a specified width, formatted it using renderers , and added some codes on it. But when i try to bind it to a model, all the columns were replaced by the fields of the model . Is there a way on how to correctly bind it? I'm avoiding loops because there are 100+ thousand records in the database. I'm trying to use other methods such as BeansBinding and EntityManager but I don't know how to change the datasource ( that's why i choose binding it to a model ) because I'm testing this to

TL;DR : In my ASP.NET MVC3 App, how should I implement a View that allows me to edit details of a 'parent' entity at the same time as the details of a list of 'children' entities ? Update : I'm accepting @torm's answer because he provided a link that gives some explanation as to why my current solution may be as good as it gets. However, we'd love to hear if anyone else have any alternative! I've been searching and reading (see the 'References' section at the bottom for some of the findings so far). However, I still feel like there's something 'smelly' with the solutions I found so far. I

This is a really strange behavior, and I've set up some demo code to try to figure out what's going on. Basically have a a two actions and a single view. The first action sends an empty model to the view, the section action recieves the model, alters its contents and sends it back to the same view. The wierdness is, in the view, the Model seems to have the updated values in it, but when I do an Html.TextBoxFor(x => x.PropertyNameHere) it renders a textbox with the unaltered value in it. lol... I apologize in advance for the toilet humor, but it keeps the day from getting too boring. ;) Does
