将viewdata传递给asp.net mvc母版页 [英] passing viewdata to asp.net mvc masterpages

问题描述

我正在尝试将ViewData传递给我在asp.net mvc母版页上保留的mvc用户控件.例如，我创建了一个名称下拉列表作为mvc用户控件，并将其放在我的母版页中.

我遇到的问题是将ViewData传递到母版页.我从Microsoft找到这篇文章，这篇文章有一个不错的解决方案，但我想知道是否还有其他更好"的解决方案.我对链接中的解决方案不满意的是，我必须更改每个控制器以从新的控制器类继承.

编辑:我要解决的问题是，如果我在依赖ViewData的母版页中放置用户控件，则必须 REPEATEDLY (重复)添加该ViewData对于使用所述母版页的每个页面.上面链接中的解决方案可能是最好的解决方案，但我希望还有其他选择.

解决方案

对于它的价值，我正在当前项目中使用该教程中的方法，并且效果很好.

如果数据有些静态(例如菜单变化不大)，您还可以做的是将对象放在缓存中，这样就不会在每次控制器初始化时都调用数据库. /p>

I'm trying to pass ViewData to my asp.net mvc masterpage for an mvc usercontrol that I keep on a masterpage. For example, I created a dropdownlist of names as an mvc usercontrol and I put that in my masterpage.

The problem I am running into is passing the ViewData to the masterpage. I found this article from Microsoft which has a decent solution but I was wondering if there are other "better" solutions out there. The thing I don't like about the solution in the link is that I have to change every controller to inherit from a new controller class.

Edit: The problem I am looking at is the fact that if I place a user control in my masterpage that relies on ViewData, I have to REPEATEDLY include that ViewData for every single page that uses said masterpage. It's possible the solution in the link above is the best solution but I was hoping there were other alternatives.

解决方案

For what it's worth, I am using the method from that tutorial in a current project and it works very well.

What you can also do, if it is data that is somewhat static (like a menu that doesn't change much), is to put the object on the cache so your database isn't called for every controller initialisation.
