I am trying to get page title from a partial page but i coundn't do it in MVC. Do you have any idea?
in a child.cshtml:
@{ViewBag.Title="this is child"} > this is not working in a child I tried to get information ViewData like:
in a viewpage.cshtml
ViewBag.Title = ViewData["pagetitle"]; in a child.cshtml:
ViewData["pagetitle"] = "this is child"; Unfortunately you cannot do it within a partial view.
The reason for this is by the time your partial view gets parsed by the view parser, the main layout (which contains the <title></title> tags) has already been written to your applications response stream ready to be flushed to the browser.
If you REALLY need to then I suppose you could parse the current response stream and use regular expression to match and replace the page title, but I wouldn't suggest this as it's pretty inefficient.
As others have said, your better option (albeit not ideal - one reason being the importance a title tag is to search engines) is set the title using Javascript.
This can be achieved like so:
<script type="text/javascript"> document.title = '@ViewBag.Title'; </script> 
ViewBag or ViewData, but because you're building it during the request for the partial, you can set a Title property on it to whatever you want. I've done this by creating a layout VM with a generic T property for the partial's VM type and I build the layout VM in a base controller so the partial's action doesn't have to worry about it. But not from directly in the view.Setting title like @{ ViewBag.Title = "..."; } in a child view will not work if you have title in your layout. Setting title is not a responsibility of PartalView.
Instead you can use javascript, like this:
document.title = "new title"; 
_Layout.cshtml? If so, how are you displaying the@ViewBag.Title?
