I am trying to understand the difference between a RenderPartial and RenderAction. I guess that RenderPartial is like a UserControl and RenderAction is like a server-side include.
View 3 RepliesI am working in an environment with many teams who are responsible for specific content on pages. Each team is sharing specific information (common class libraries, and master pages) that each are going deliver different types of content.Is it possible for an MVC application to do something similar to RenderPartial and pass a model to another MVC application Controller/Action to return content?
So the code for this might look like:
(http://www.mydomain.com/Home/Index)
<% Html.RenderAction("ads.mydomain.com", "Home", "Index", AdModel) %>
Maybe this is not a good idea as another thread has to spin up to server a partial view?
Also RenderAction and Action. RenderXXX akaik write directly to response stream and XXX use additional string buffer. I don't really want doing benchmark my myself, so maybe someone already do it.

Whats the difference between Url.Action and Html.RenderActionLink in asp.net mvc?
View 1 RepliesI'm using MVC 2 and MVC Futures 2.0.50217.0.
I started with a view which repeatedly calls RenderAction(...) to include some external content implemented by another controller in my application. This is from the containing view:
[Code]....
The subModel objects are instances of the model for the MyController.MyAction view which has some Data Annotations validation attributes upon it. MyController.MyAction checks the model state is valid before it renders its view and chooses a view appropriately. This works fine.
However, if I use the MVC Futures' strongly typed helper to call RenderAction like so:
[Code]....
...then the validation is not performed. Or at least, the model state does not indicate that the model is invalid.
Does anybody know what's the difference between Html.RenderAction and Html.Action?
View 2 RepliesI read many posts about outputcaching element in asp .net MVC, but i have one question.My architecture is :1 master page, 1 page (especially news information), and a few other controls like LogOnUser / Fixed status bar etc...I want to have my news cached cause there are three query to entities, but i need too the title for SEO of my master page (title is included in a contentplaceholder in master).I tried to use renderaction outputcache but it is not possible to retrieve the title from the renderaction. Have you any idea about this problem ?Maybe it's preferable to use a general outputcache and use a substitute from dynamic data, but i don't know if it's a best practice or not.

I want to use RenderPartial twice in my view with different models associated. The problem is that some properties are present in both models (nickname, password). They have no prefix, so even the id's or names are equal in the output. Now, if I have model errors for nickname or password, both fields get highlighted.

How can I change this?
I'm using both spark and .aspx view engines. My partial is in aspx so i'm tring to call from my spark engine.
I've seen something like the following
${Html.RenderPartial("HeaderControl")}
Seems like i'm missing a reference, can't really see what.
Dynamic view compilation failed. d:WebsiteViewsRetailerIndex.spark(11,23): error CS1061:
'System.Web.Mvc.HtmlHelper' does not contain a definition for 'RenderPartial' and no extension method 'RenderPartial' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)

I've got a container object that holds the various objects required by the partial views contained in a regular view. I changed from passing the entire object into each partial view to passing just the object the view needs, but I ran into an odd error.I'll post the code. The first RenderPartial that's called worked just fine. The second one, which is identical in every regard I can see but the actual contents, is the culprit. I get a HttpCompileException, stating that:
...ProjectUpdater.ascx(97): error CS1061: 'DSC.Data.Model.Shared.ProjectUpdaterInfo' does not contain a definition for 'ProjectUpdater' and no extension method 'ProjectUpdater' accepting a first argument of type 'DSC.Data.Model.Shared.ProjectUpdaterInfo'
could be found (are you missing a using directive or an assembly reference?)
Here's the view code:
[Code]....
I get intellisense for the Model.ProjectUpdater, and nothing shows up with the squiggly lines indicating an error. Here's the properties of the model class:
[Code]....
So there's the ProjectUpdater I'm getting an error saying doesn't exist. What's driving me nuts is that the first RenderPartial is working fine.
We are using renderaction provided by MVC futures. We've noticed that HttpExceptions in child action methods are not propagated to the parent action. Even though a fragment has failed, we still see the parent request resulting in a 200, and this throws our error handling for a toss.
View 4 RepliesI have an action that generates active vacancies. The code is below;
[Code]....
I want to use this list on several pages so i guess the best thing to use is html.renderpartial.
I then created a view by right clicking inside the action and create a .ascx and a strongly typed view of Vacancy. I chose a view content of "List".
I then added this line to the required page;

I upgraded a MVC1 project to MVC2, now all my calls to RenderPartial are throwing
System.ArgumentNullException: Value cannot be null.
However this does works:
<% Html.RenderPartial("~/Views/Shared/LogOnUserControl.ascx"); %>
And this does not (works in MVC1):
<% Html.RenderPartial("LogOnUserControl"); %>
Did the behavior of RenderPartial change?
I am making my first attempt at using RenderPartial to display a list of objects, but so far having little success. Here is my code, can somebody give me some guidance on what I am doing wrong?
[Code]....
I am using MVC 2 and am having problems getting the OutputCache to work. My ASP.NET website has Several Views and a View Master Page. On my View Master Page I have a Menu on the left hand side displaying navigation links (implemented using JQuery).
I have implemented the Menu as a PartialView and I call this PartialView from my MasterPage using Html.RenderAction. This all works fine, my controller fetches the data from the database and the PartialView is populated.
The problem is I want to cache the Menu data since it's consistent on all pages. Yet when I add the OutputCache parameter to my Action it has no effect.

i have the following, which works:
@{Html.RenderAction("Detail", "Help", new { pageName = "press" });}
But instead i'd like to use a lambda expression to get away from the string bits. I tried using the following (which is the nearest approximation i could figure based on my limited knowledge of the engine):
@{Html.RenderAction<HelpController>(x => x.Detail("press"));}
But i get the following error:
The non-generic method 'System.Web.Mvc.Html.ChildActionExtensions.RenderAction(System.Web.Mvc.HtmlHelper, string, string, System.Web.Routing.RouteValueDictionary)' cannot be used with type arguments
However, i'm reading in the Apress MVC 2.0 book that it is in fact declared as a method that takes type arguments. Am i missing an assembly reference, or has it not been included in the MVC 3.0 Preview 1 build?
i have this (simple) code
<% Html.RenderAction("Version", "Generic"); %>
in my masterpage of my asp.net mvc 2 app. This method returns the version of the application.
i also have this code in my controller:
class GenericController : BaseController
{
[ChildActionOnly]
public string Version()
{
try
{
string assemblyFile = Assembly.GetCallingAssembly().FullName;
FileInfo fi = new FileInfo(assemblyFile);
string version = fi.LastWriteTime.Year.ToString( ) + fi.LastWriteTime.Month.ToString() + fi.LastWriteTime.Day.ToString();
return version;
}
catch (Exception e)
{
return "1.0";
}
}
}
Now i get this error:
Execution of the child request failed. Please examine the InnerException for more information.
and the innerexcpetion is:
{"The controller for path '/Account/LogOn' was not found or does not implement IController."}
What i was thinking is that maybe the code can't execute because the user is not logged on yet, and tries to redirect to the logon method etc.
So the first thing i was thinking is to grant access in the web.config (like i do with the directory that has the css and images in it, it should also be accessable when you're not logged on:
<location path="Content">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
but what is the path for this (version) method ?
(or maybe there is another reason for the excpetion.
im extending the htmlhelper. but it i cannot call the renderaction of it.
using System.Text;
using System.Web.Mvc;
using System.Web.Mvc.Html;
public static class ViewHelpers
{
public static string Text(this HtmlHelper htmlHelper, string name, object value, bool isEditMode)
{
htmlHelper.RenderAction(...) //cannot be called
}
}
how can i call the RenderAction?
im getting the following exception for use into a master page the helper html.renderpartial(). This works on mvc views that uses this master page, but im trying to execute an old aspx webform page that uses the same masterpage. And here comes following exception:A ViewMasterPage can be used only with content pages that derive from ViewPage or ViewPage.This is the code of my master page:
<body>
<%Html.RenderPartial("PartialView"); %>
<div style="background-color:Aqua;">
<asp:ContentPlaceHolder ID="MainContent" runat="server">
</asp:ContentPlaceHolder>
</div>
</body>
I would like to render some partialviews on my master page. Is it possible?
What I'm trying to do is use one master page with two different layouts. Currently we have a "master" master page that has all the common elements and two master pages that use it for the two different layouts. This gives us 3 master pages and there's developer confustion and it is a bit of a hassle to keep them consistent. What I'd like to do instead is say "if there's anything in the MainContent ContentPlaceHolder, show the single column layout, otherwise show the two column layout".
From what I've read you're supposed to be able to do this by using something like the following:
[Code]....
But this.MainContent.Controls.Count retuns zero when the ContentPlaceHolder uses Html.RenderPartial. For example, this works fine:
[Code]....
This causes this.MainContent.Controls.Count to return 1. If I remove MainContent from the view, it returns 0, as expected. However, if I do this:
[Code]....
Then this.MainContent.Controls.Count returns zero.
I would like to wrap a RenderPartial in a JsonResult so that my jQuery can handle placement/positioning of the html data based on additional Json parameters.
e.g. {html: <string returned from RenderPartial>, typeofdata: 1}
After Googling, it seems that the only way to do this is a workaround that hijacks HttpContext in order to spit the PartialViewResult into a string. However, this seems like it would break testability.
Is JsonResult not intended to be used with RenderPartial?
Alternatively, I could set typeofdata as a parameter of the model, and have the PartialView render it as a hidden field, then have jQuery look for it. What is a better way to generate the data that I need?
I have two views in the same folder. View.aspx and a partial
View.ascx
In view.aspx i call RenderPartial
<% Html.RenderPartial("View",MyModel); %>
and MVC renders View.aspx not the partial View.ascx. The net result is an endless loop which eventually causes IIS to shutdown the application.Personally I was expecting the partial view to be rendered.
I'm using ASP.NET MVC 2 Beta. I made a sample code to describe my question.
In the /Controller/HomeController.cs
using System;
using System.Web.Mvc;
namespace MvcApplication9.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Index()
{
return View();
}
}
}
