编辑多个子记录ASP.NET MVC的例子 [英] ASP.NET MVC example of editing multiple child records

问题描述

有谁知道一个MVC视图，显示所有的一种形式父/子数据，并允许所有的子记录为可编辑的任何实例或教程？

Does anyone know of any examples or tutorials of an MVC view that shows parent/child data all on one form, and allows all the child records to be editable?

例如，说我有一桌子的人，另一个包含他们所拥有的车辆。其中一种形式，我想告诉所有车辆为特定人，使数据元素编辑（即车牌号，车色等）的情况下，也有错误。我不想跳到每辆车一个单独的编辑表单。

For example, say I have a table of people and another containing the vehicles they own. One one form, I want to show every vehicle for a given person, and make the data elements editable (i.e. license plate number, car color, etc.) in case there are mistakes. I don't want to jump to a separate edit form for each vehicle.

我尝试迄今已经得到我的地方，我可以显示的数据点，但我不能让它回发到控制器。我试图尽量缩小问题，我可以<一个href=\"http://stackoverflow.com/questions/709933/child-records-not-posting-on-asp-net-mvc-form\">here,但我仍然没有得到它，我觉得更广泛的例子可能是为了。任何想法？

My attempts thus far have gotten me to the point where I can display the data, but I can't get it to post back to the controller. I've tried to narrow down the problem as far as I could here, but I'm still not getting it, and I think a broader example may be in order. Any ideas?

推荐答案

您可以尝试这样的事情。

You can try something like this.

假设你有这个对象：

public class Vehicle
{
    public int VehicleID { get; set; }
    public string LicencePlate { get; set; }
    public string Color { get; set; }
}

这是你用来编辑细节的车辆（在这里您可以发布形式）的控制器动作：

And this is your controller action that you'll use to edit vehicle details (where you'll post the form) :

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult EditVehicles(int Owner, Vehicle[] vehicles)
{
    //manipulate the data, then return back to the list
    return RedirectToAction("YourAction");
}

那么你应该设置你的表格是这样的：

Then you should set your form this way :

<!--have a form for each person, listing their vehicles-->
<form action="/EditVehicles" method="post">
    <input type="hidden" name="Owner" value="25" />
    <input type="hidden" name="Vehicles[0].VehicleID" value="10" />
    <input type="text" name="Vehicles[0].LicencePlate" value="111-111" />
    <input type="text" name="Vehicles[0].Color" value="Red" />
    <input type="hidden" name="Vehicles[1].VehicleID" value="20" />
    <input type="text" name="Vehicles[1].LicencePlate" value="222-222" />
    <input type="text" name="Vehicles[1].Color" value="Blue" />
    <input type="submit" value="Edit" />
</form>

这将有助于正确地绑定在你的控制器中的表单数据模型的DefaultModelBinder。因此，的Response.Write（车辆[1]。颜色）; 控制器上，将打印蓝

This will help the DefaultModelBinder to correctly bind the form data to your model in your controller. Thus Response.Write(vehicles[1].Color); on your controller, will print "Blue".

这是一个很简单的例子，但我敢肯定你的想法。有关结合形式，数组，列表，集合，字典更多的例子，看看<一个href=\"http://www.hanselman.com/blog/ASPNETWireFormatForModelBindingToArraysListsCollectionsDictionaries.aspx\">here.

This is a very simple example, but I'm sure you get the idea. For more examples about binding forms to arrays, lists, collections, dictionaries, take a look at here.
