如何将数据传递到我的布局PartialView？ [英] How to pass data to a PartialView in my layout?

问题描述

我有一个包含此行一个_layout.cshtml：

I have a _layout.cshtml containing this row:

@{Html.RenderPartial("Menu");}

现在我想在一个模型传递到这个的RenderPartial功能。这种模式可以从我的资料库中读取。

Now I want to pass in a model into this RenderPartial-function. This model can be read from my repository.

如何以及在哪里（在code）可以这样做？

How and where(in code) can this be done?

谢谢！

推荐答案

的RenderPartial有，可以采取一个目的是将其发送给局部视图超载。
不要忘记在你partialview顶部的定义@model用正确的对象类型的工作。

RenderPartial has an overload that can take an object to send it to the partial view. Don't forget to define your @model at the top of your partialview to work with the right object type.

@ Html.RenderPartial（视图名对象）

@Html.RenderPartial("ViewName",object)

评论后编辑：

我认为这将是更容易地创建一个MenuController这需要在库中。然后让它创建一个视图这需要在要求的资料库，因为它的模型，然后用一个foreach渲染每一个菜单项为actionlinks，通过菜单的信息吧。

I think it would be easier to create a MenuController that takes in the repository. Then let it create a view which takes in the required repository as it's model, then with a foreach render every menu-item as actionlinks, passing the menu info to it.

所以，你将有这你_layout.cshtml：

So you would have this in your _layout.cshtml:

<div id="Menu">
    @{Html.RenderAction("Menu", "Menu");}
</div>

这在您的MenuController：

This in your MenuController:

public class MenuController : Controller
{
    private IMenuRepository _repository;

    public MenuController(IMenuRepository repo)
    {
        _repository = repo;
    }
    //
    // GET: /Menu/

    public PartialViewResult Menu(string menu = null)
    {
        ViewBag.SelectedMenu = menu;

        IEnumerable<MenuInfoObject> menus= _repository.Menus;
        return PartialView(menus);
    }
}

和您的MenuView：

And your MenuView:

    @model IEnumerable<MenuInfoObject>
@{
    Layout = null;
}
@foreach (var item in Model)
{
    @Html.RouteLink(item.MenuName, new
{
    controller = item.ControllerInfo,
    action = item.ActionInfo,
}, new
       {
           @class = item.Menu == ViewBag.SelectedMenu ? "selected" : null
       })
}

请问这是任何更接近的解决方案？

Would that be any closer to a solution?
