ASP.NET MVC Issue with Using Reflection Created Objects with the Default Model Binder

由 人走茶凉 提交于 2019-12-11 05:34:36
问题 I am having a weird issue in ASP.NET MVC with objects not being updated with UpdateModel when passed a formCollection . UpdateModel does not appear to be working properly when the object being updated is created through reflection. Scenario: I have an application which has approximately 50 lookup tables--each of which includes exactly the same schema including typical fields like id, title, description, isactive, and createdon. Rather than build 50 views, I wanted to have a single view which

ASP.NET MVC 2 UpdateModel() is not updating values in memory or database

由 a 夏天 提交于 2019-12-06 04:37:58
I am new to MVC, and so am working through the NerdDinner tutorial, here . In particular, I'm running into problems with the use of the UpdateModel method, which is explained in the part five of that tutorial. The problem is, when I try to edit the value of a dinner object using the UpdateModel method, the values do not get updated, and no exceptions are thrown. Oddly, I am not having any trouble with the Create or Delete features that are illustrated in the tutorial. Only the update feature isn't working. Below, I have included the Controller code that I am using, as well as the view markup,

问题 Let's say that you have a Model that looks kind of like this: public class MyClass { public string Name { get; set; } public DateTime MyDate { get; set; } } The default edit template that Visual Studio gives you is a plain textbox for the MyDate property. This is all fine and good, but let's say that you need to split that up into it's Month/Day/Year components, and your form looks like: <label for="MyDate">Date:</label> <%= Html.TextBox("MyDate-Month", Model.MyDate.Month) %> <%= Html.TextBox
