Page title problem when setting ViewBag variable from razor section in asp.net mvc
Consider fallowing declaration in view
@section sideaction
{
...
ViewBag.Title=Model.Title;
...
}
And in main layout i have this
<head>
<title> @ViewBag.Title</title>
....
...
</head>
..
...
<body>
..
@RenderSection("sideaction",required:false)
..
</body>
I am not getting 开发者_Python百科title from view, i know that view will be processed before layout but i recognized that head section is processed before render section which is causing this problem. One more thing , ViewBag.Title=Model.Title is just an example , the real Model is IEnumrable object and i am iterating and finding proper title. I can iterate in controller to find title but there is already iteration in view. For big collections one iteration is more efficient. Any ideas?
You cannot set a ViewBag value in a section.
Use this:
@{
ViewBag.Title = Model.Title;
}
directly in the view to set a title.
Even it doesn't work, notice that the code has to be like this:
@section sideaction
{
@{
ViewBag.Title = Model.Title;
}
}
But as other people mentioned earlier, you can't do it this way inside a section. You should put it directly inside your view:
@{
ViewBag.Title = Model.Title;
}
By the way, if you persist to change title of a page from inside a section, use javaScript/jQuery, e.g:
@section sideaction
{
<script type="text/javascript">
$(function () {
document.title = '@Model.Title';
});
</script>
}
Note: pay attention that it has to be '@Model.Title' (inside quotes).
