Asp.Net MVC动态模型绑定前缀 [英] Asp.Net MVC Dynamic Model Binding Prefix

问题描述

是否可以使用来自请求参数的值来更改绑定前缀?

Is there any way of changing the binding prefix with a value which comes from the request parameters?

我有很多嵌套的搜索弹出窗口，并且它们都共享相同的ViewModel.

I have many nested search popups, and all of them shares the same ViewModel.

我可以在请求搜索过滤器时向所有字段添加绑定前缀，但是我不知道如何使[Bind(Prefix =")]与来自请求参数的值一起使用.

I can add a binding prefix to all the fields when requesting for the Search filters, but i don't know how can i make the [Bind(Prefix = "")] to work with values coming from the request parameters.

// get the search filters with the bindingPrefix we need
public ActionResult Search(string bindingPrefix)
{
    ViewData.TemplateInfo.HtmlFieldPrefix = bindingPrefix;
    SearchViewModel model = new SearchViewModel
    {
        BindingPrefix = bindingPrefix
    };

    return PartialView("_SearchFilters", model); 
}

// post the search filters values
[HttpPost]
public ActionResult Search([Bind(Prefix = model.BindingPrefix)]SearchViewModel model)
{

}

推荐答案

我不知道您为什么要这样做，但这应该可行.

I don't know why you would want to do this, but this should work.

在视图上的表单中，具有隐藏值

In your form on the view, have a hidden value

@Html.Hidden("BindingPrefix", Model.BindingPrefix)

将操作修改为以下内容

[HttpPost]
public ActionResult Search(SearchViewModel model)
{
    UpdateModel(model, model.BindingPrefix);
}
