I've began working with asp.net mvc very recently and I've ran into a problem.I've got an aspx page which renders a few ascx pages. What I'd like to do is declare a global var at the aspx page so it is visible to all its childs. I tried <% var i = 0; %>
but it wasn't visible at the child pages.
我能怎么办?
推荐答案
从一个aspx页面变量不与局部视图共享。视图是一个数据的只是一个再presentation。你要传递的数据为模型,每个视图要呈现,无论是普通视图或PartialView。
variables from a aspx page are not shared with the partial views.The view is just a representation of a piece of data. You have to pass the data as a Model to each view you want to render, whether it's a plain View or a PartialView.
<% Html.RenderPartial("ViewName", Model, ViewDataDictionnary) %>
如果你想给一个变量传递给局部视图,我会强烈建议您将此参数添加到局部视图的模式,而这额外地通过ViewDataDictionnary通过。
If you want to pass a variable to a partial view, I would strongly recommend you to add this parameter to the model of the partial view, rather that to pass it additionally via the ViewDataDictionnary.
