ASP.Net MVC控制器_layout [英] ASP.Net MVC Controller for _Layout
问题描述
我工作的MVC动态菜单系统,只是使它工作,我创建了菜单的局部视图,它使用下面的语法的伟大工程:
@ Html.RenderPartial(_菜单,(Models.Menu)ViewBag.MainMenu)
但是,要做到这一点,我将不得不设置在ViewBag的主菜单,FooterMenu(或与此有关的任何其他菜单)上的每个控制器和每个动作。为了避免这种情况,我想知道如果有,我可以在全球访问ViewBag推荐的事件。如果没有,有没有人建议通过菜单对象到一个会话变量?这听起来不是我的权利,但我唯一能想到的现在。
更新:
_Layout.cshtml - 我列入到行动新的呼叫:
@ Html.Action(RenderMenu,SharedController,新的{名=主})
SharedController.cs - 增加了新动作:
公众的ActionResult RenderMenu(字符串名称)
{
如果(db.Menus.Count&所述;菜单>()大于0&放大器;&放大器; db.MenuItems.Count&下;菜单项>()&0)
{
菜单菜单= db.Menus.Include(的MenuItems),单<菜单>(M = GT; m.Name ==名);
返回PartialView(_ MenuLayout菜单);
}
其他
{
返回PartialView(_ MenuLayout,NULL);
}
}
和它抛出以下异常:
有关路径控制器'/'没有被发现,或者不执行
一个IController。
块引用>更新2:
所以,问题是,我的全名中引用的控制器,你只需要在控制器的名字去掉控制器。整齐的珍闻。因此,我的例子,这个作品:
@ Html.Action(RenderMenu,共享,新的{名=主})
解决方案设置你的菜单了作为一个动作,然后把它在你的总体布局。
使用@ Html.Action()
动作可以返回在它的菜单code的局部视图。
I am working on a dynamic menu system for MVC and just to make it work, I created a partial view for the menu and it works great using the syntax below:
@Html.RenderPartial("_Menu", (Models.Menu)ViewBag.MainMenu)
BUT, to do so, I would have to set the MainMenu and FooterMenu (or any other menu for that matter) in the ViewBag on each Controller and each action. To avoid this, I was wondering if there was a recommended event that I could access the ViewBag globally. If not, does anyone recommend passing the Menu object into a session variable? It doesn't sound right to me, but only thing I can think of right now.
UPDATE:
_Layout.cshtml - I included the new call to Action:
@Html.Action("RenderMenu", "SharedController", new { name = "Main" })
SharedController.cs - Added New Action:
public ActionResult RenderMenu(string name) { if (db.Menus.Count<Menu>() > 0 && db.MenuItems.Count<MenuItem>() > 0) { Menu menu = db.Menus.Include("MenuItems").Single<Menu>(m => m.Name == name); return PartialView("_MenuLayout", menu); } else { return PartialView("_MenuLayout", null); } }
And it throws the following exception:
The controller for path '/' was not found or does not implement IController.
UPDATE 2:
So, the issue is that I referenced the Controller by the full name and you only need the name of the controller minus "Controller". Neat tidbit. So, for my example, this works:
@Html.Action("RenderMenu", "Shared", new { name = "Main" })
解决方案set your menu up as an action then call it in your master layout.
use @Html.Action()
the action can return a partial view with your menu code in it.
