I have a razor partial view. I want to use it in an aspx view.
How can I do this?
My understanding is that RenderPartial() cannot call a different view engine, but using RenderPage() will allow you to use a different view engine.
Edit:
Looks like you should have no problems rendering an aspx view in a razor page using RenderPartial()
If you have your action method return a "PartialViewResult", it will know how to render whatever partial you return, either ascx or razor. It's all HTML in the end.

I have a complex asp.net mvc view where I load an "ascx" partial view into a div using $.ajax(). So I was wondering about the accessibility of the DOM elements contained in the main page and the ascx partial view. Using jQuery selectors, can I find an element in the main page from the ascx partial view? and the other way round?
Both ways, depending on the point on time.
You can always access the elements from the main view, since the HTML is bound at render-time (e.g $(document).ready())
You won't be access the elements in the partial view from the parent view until the callback from the $.ajax method has completed successfully and you have binded the HTML to the DOM (with .html(result) for example).
I have a few views on my website that i need to include on a start page. However, just using Html.Renderaction renders the master page and the whole shebang.
How would i go about just rendering the content?
There are a few ways.
Make sure your returning PartialView from your Controller.
return PartialView("MyView");
Or you can set Layout to String.Empty or null inside the view.
#{
Layout=String.Empty;
}
In MVC 3 Beta, is there a difference between the templates MVC 3 Partial Page (Razor) and MVC 3 View Page with Layout (Razor) ?
I added a partial page (_partialList) to my application. Now when I return only the partial view, it applies the Layout present in _ViewStart.cshtml - acting very much like a stardard view page with layout.
if (Request.IsAjaxRequest())
return View("_partialList", someModelData);
How does a "partial" page distinguish itself from a standard view page with layout ? Will the two behave differently in any particular scenario?
If you don't want to apply the layout return a PartialView instead of View:
if (Request.IsAjaxRequest())
return PartialView("_partialList", someModelData);
Darin's response solves your practical issue of not wanting the layout to be applied.
Regarding the difference between the two, in Razor they are practically the same because both full pages and partials use the same extension and have the same base class.
The reason why there is different UI is because in the Web Forms view engine the two are implemented with different extensions and different base classes, which is why to seperate templates are necessary.
Add the following code to your page, and the view engine will not apply the layout to it.
#{
Layout = null;
}
Views have this
#{
View.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
and partial views don't
I don't think there is any difference.
What is the difference between a View and a PartialView in ASP.NET MVC?
At first glance the need for both seems non-obvious to me.
In theory, the answer is: A partial view is a "sub-view" that you embed within a main view - something that you might reuse across multiple views, like a sidebar.
In practice, the answer is: Very little.
In theory, partial views are more lightweight than standard views, but it's perfectly OK to pass a "regular" view to RenderPartial and the performance seems to be exactly the same. I frequently use regular .aspx views as "partial" views because you can make them reference a master view in order to provide templated content like what you can do with UserControls in ASP.NET WebForms. See here.
Partial views are more like web parts on a portal - they are completely self-contained objects. Use them if the layout is simple and static, or if you're annoyed by the Intellisense errors when you don't have the <html> and <body> tags in a standard View.
It works like that:
return View() the view content goes in the #RenderBody() of the /Shared/_Layout.cshtml
return PartialView() it returns only the view content
Views are the general result of a page that results in a display. It's the highest level container except the masterpage. While a partial view is for a small piece of content that may be reused on different pages, or multiple times in a page.
If you're coming from webforms, view is similar to a web content form, while a partial view is like a user control.
If you come from a webforms background, think of PartialView as a usercontrol.
Look at StackOverflow.com site:
Main site (View) contains components like:
Tags
Related
Ad
So Tags, related, Ad etc. can be composed as PartialViews. The advantage of this is that
PartialViews can be simply cached by OutputCache instead of recreating all site: performance gain.
Consider a partialview like a control in webforms, the idea is the partial is reusable
View in Core Mvc
View Contains The layout Page(_ViewStart) Or Layout Property.
#{
Layout="_Layout"; }
Before Any View Rendered _ViewStart is Rendered.
View might have markup tags As
<!DOCTYPE html>
<html>
<head>
</head>
<body>
</body>
</html>
View isn't Lightwight as Partial View.
View will Render in Layout by used #RenderBody() Method
(Views/Shared/_Layout.cshtml).
Calling by use return View() inside Action.
Partial View
Partial view doesn't Contain Layout Page Layout Property
It does not verify for a viewstart.cshtml. We cannot put common code
for a partial view within the viewStart.cshtml.page.
In MVC Partial view is designed specially to render within the view
We can pass a regular view to the RenderPartial method.
#{await Html.PartialAsync("Partial"); }
Example To Demo Partial View Is Strongly Type
in View
#model List<Student>;
#{
Layout = "_Layout";
}
<div>#await Html.PartialAsync("Partial",Model)</div>
in Partial View
#model List<Student>; <ul>
#foreach (Student student in Model)
{
<li>#student.ID</li>
<li>#student.Name</li>
<li>#student.Age</li>
}
</ul>
SP.NET Core MVC looks for Partial View in the same way like Regular
Views (i.e. in Views/ and Views/Shared folders). This
means you can create controller specific partial views or shared
partial views.
Good Luck
I have a number of partial views that are used to render media in different formats (embedded video mainly). I now have a requirement that has me displaying these videos inside an iframe. Is there a way that I can return a minimal HTML page with the partial views embedded in it?
