MVC Rendering (RenderPartial, RenderAction) Html From Another MVC Application
Sep 9, 2010
I 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?

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.

I have a Microsoft MVC project with an action "Foo" whose view ("Foo.aspx") contains the lines:
<%= Html.ActionLink("mylinktext1", "bar") %>
<%= Html.ActionLink<MyController>(x => x.Bar(), "mylinktext2") %>
When I hit this from a web browser or load it from an AJAX call, it properly returns:
<a href="/bar">mylinktext1</a>
<a href="/Bar">mylinktext2</a>
But when I call the action from another view like this:
<% Html.RenderAction<MyController>(x => x.Foo()); %>
Then the links are rendered without targets.
<a href="">mylinktext1</a>
<a href="">mylinktext2</a>
Why would this be happening, and how do I work around it?

It's a little unclear for me on when to use a custom helper method and when to use RenderAction and also when to simply use ViewData instead. Some of their functions overlap slightly.
For example, if I were to create a Category navigation bar, would I create a new helper method and place that in some partial view? I had initially though of doing this, but I read on some blog to use RenderAction instead.
Assume the list of categories is coming from some data source.

I 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;
[Code]....

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.

After rendering a view on a Post, a call to RenderAction inside the view will call for the Post method. Is there any way to specify I want to call the Get method instead of the Post?

Ive tried [OutputCache] for a view that is rendered from Html.RenderPartial, but it doesn't work! It works perfectly for 'normal' views.
How do I cache output for partial view?

I'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.

In my Site.Master View, I have the following line:
[Code]....
If I don't include the string identifying the Controller to use, I get an error stating that the PrimaryNavigation method couldn't be found in the Home Controller. Since the Site.Master View is in the Shared Views folder, I would have thought that the Shared Controller would have been used.

Basically the operation of the screen is the following, make the creation of a parent record and then join the other records. I want to save the parent record and associated records.

I have implemented a custom ModelMetadataProvider so that I can decorate my view models with some custom attributes and everything was working fine until I made use of a Partial View. The following code in my view works fine: -
<%: Html.DisplayFor(x => x.Results) %>
Results is a List which renders a custom display template and is also decorated with a custom attribute. Using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. If I look at the attributes collection parameter I can see that it does contain my custom attribute thus everything working as expected. However, if I replace the above with the following line of code in my view then it breaks: -
<% Html.RenderPartial("ApplicationSearchResults", Model.Results, new ViewDataDictionary()); %>
All the Partial View contains is: -
<%: Html.DisplayFor(x => x) %>
Again using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. But this time if I look at the attributes collection parameter my custom attribute is not there.

The following link describes the relationships between a Partial View and its parent in terms of ViewData: [URL] In relation to the text: "A partial view enables you to define a view that will be rendered inside a parent view. Partial views are implemented as ASP.NET user controls (.ascx).
When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed"
how the parent view can make use of the new data added or existing data changed and updated, by the partial views? My question is around how to load partial views dynamically at runtime using Html.RenderPartial(...) whilst having one version of the data used and updated by the parent view and it's children.

I get an HttpException (details below) after installing Visual Studio 2010 Pro RTM in an application developed using Visual Studio 2010 RC. The platform used was ASP.NET MVC2 RTW (already under VS10 RC).
I first uninstalled all RC software and even ASP.NET MVC 2, and then did a "clean" install of VS10 RTM. The ASP.NET MVC 2 version now installed on my dev machine is 2.0.50217.0.
Exception Message: Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.
InnerException Message: <FilePath>ViewsLanguageRenderLanguageNavigation.ascx(6): error BC30451: 'Model' is not declared. It may be inaccessible due to its protection level.
The error occurs on this "Html.RenderAction":
[Code]....
The "LanguageController" just calls into another service function as below:
[Code]....
Does anybody have an idea what is causing the problem?
Edit:
By the way, I might also share the actual view (partial view) that would show the languages to select from:
[Code]....

I cannot seem to get over this problem. Im sure it is just a simple newbie question but I just cannot find the right answer on my own.
Im using MVC 2 and ASP. NET 4.0 to biuld simple CMS. Im storing encoded HTML in XML file which then i am passing to front page controller for display.
I understand that before inserting HTML from XML into the page, it should be decoded using HttpUtility.Decode() function.
[Code]....
I expected that this sould result in inserting decoded HTML into my index.aspx page. Then browser could render my decoded content for example in bold face.
What happens is quite awkward. In page source I have encoded HTML but it renders HTML with tags. For example I see "<strong> Lorem ipsum </stong>", instead of Lorem Ipsum.

I find it hard when using asp.net controls, to make proper css files because I don't know what the html output for the different controls end up as. For example, if I want to add a div tag using a asp.net control, it's not easy to know what kind of control I can use.
Are there any documentation that shows for each asp.net control, what the rendered html for that control will be? I understand that some controls will probably change it's output due to how it's configured, but most controls will at least follow a pattern here.
The best would of course be a service on the web where you can put in the asp.net control definition and get the rendered html out. Currently I have to put a control into my webform, run it and check the source in the browser, and if it's not the correct html tag, try another control and repeat. That get's tedious quite fast.

I was wondering if it's possible to render an Html Helper in a View inside a codeblock. So instead of:
[code]....
And have this render. Of course as it is, it wont render, so is there a way to programically decide if a textbox can be added without having to have a million delimiters in the page to accomplish this?
