I want allow the user to customize their web pages on my ASP.NET MVC website, so they can use their own style sheet. In MVC, the stylesheet link is placed in the section of the master page. How can I dynamically link to CSS in master page based on the user (that is, I will look up my table to find the CSS for a specific user and link to it).
Thanks!
I would use a ContentPlaceHolder in the tag (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.contentplaceholder.aspx) for the master page and apply the data you want per the View you're showing.
I would have your view specific view models inherit from a common base view model, then have a property on this base view model that gets set in your controllers. Your masterpage can then set the correct css link dynamically without having to repeat code in a ContentPlaceHolder on every single view.
how about using the old school passing the path to your custom controller in the src tag
with your MyCssController redirecting to the custom path based on your logic ??

Just playing around with Sitecore 7 and MVC, and I try to get the rendering basics working.
So far, I have been able to create a View Rendering (and mapped to the relevant .cshtml file) within the Renderings section, and applied these to the presentation details of the item (in much the same way you do with ASPX Layouts/ASCX Sublayouts).
I have also been able to map the Item to a controller (using the Controller and Action fields on the item), have the Index action on the controller (inherited from SitecoreController) return the view ~/Views/Home/Index.
The issue I can't seem to wrap my head around is merging the two rendering methods. I want to be able to create controllers that map to an Item, but render the item using the ViewRenderer, rather than using the default MVC conventing of return View(), so that I can:
Specify the location of the view files within a multi-site environment by setting the path parameter of the rendering; and
Have content authors/managers manage the renderings the way that the Layout/Sublayout does with place holders.
Does anyone know of a way that this can be achieved?
Have you taken a look at Controller Renderings in Sitecore MVC? These give you the ability to map a controller class to a Sitecore presentation item that can be statically or dynamically bound to your layout details.
This post has a reasonable overview of how to get started with controller renderings.
As for specifying the location of View files for multi-site environments you can pass the path to the razor file into the Controller View method, for example:
return View("~/Areas/SampleArea/Views/SampleArea/Index.cshtml");
I hope this helps.
I am new with MVC framework. When I was using Web form, the user control can be assigned parameter in the Page and can be Generated unique ID in the Page. Even though you implemented the control more than one time in the same page.
In MVC framework, Partial View is the only way to implement reusable control. I got some problems below.
How to Implement same reusable control more than once in the same page with different parameters.
I know RenderPartialExtensions.RenderPartial can pass different
ViewData, but if the partial view is implementing some
JavaScripts/Jquery, it would generate issue with Id in the same page
You can differentiate that id within passed models . you can put for example some unique member for that model and use inside partial view :
<p id="element#(Model.unique.ToString()) ></p>
Or avoid id selection inside jscript at all. for example use class selectors
HI I am just learning asp.net mvc 3 and I am tryng to create a common menu for my entire application.I understand I can do that in _Layout.cshtml file witch is the default template for every page.
Now I have looked into sections for adding a template insite _Layout.cshtml but from what I can gather I need to define the section in every view.
I already have the logic for accesing the data defined in a separate class.All I need is to call the method witch will return a Dictionary<string , List<string>> , and then display the data by looping into it.
Aldo I could probably do this directly inside the Index.cshtml file by using the razor syntax I believe there must be a better way
So is there a way to create a template that can then bee added inside the _Layout.cshtml?
Creating a section for the menu on each view could work but I think another approach could be easier to mantain. On your layout itself use #Html.Partial to render your menu. Then on that partial view you could have all kinds of operations, such as database access, in one single spot.
Here is an article on how to do exactly this:

Was just looking into something similar. Hopefully partial views are your answer, this is a template you can re use and stick on any page. Information found here.
asp:PlaceHolders have a visible property, and this controls whether their content is rendered on the page.
I have declared a PlaceHolder in an MVC2 Master Page and set it's visibility to false.
Please can you tell me how I can control the visibility of a PlaceHolder from within an MVC2 view template that inherits from an MVC2 master page?
This seems like a simple task, but I am struggling to see how it can be achieved. I think I should be able to get access to the PlaceHolder from within the descending view template (as with web forms code-behind) and just set it's visibility there but the way to do this is escaping me...
Don't do this. Placeholders are legacy from classic WebForms. Manipulating server side controls in an ASP.NET MVC application is very bad and you should never do it. So simply forget about setting properties on user controls. Fortunately in Razor placeholders have been completely removed and replaced by sections. So don't write code that you won't be able to migrate later.
One way to show/hide sections of your code in an ASP.NET MVC application is to use an if statement in your views. For example:
<% if (Model.ShouldShowSection) { %>
<div>Some super section</div>
<% } %>
In this example we are testing a boolean value on the view model which the controller action that rendered this view would set.
I have existing ASP.NET MVC View pages and View user controls which I currently use in normal straightforward ASP.NET MVC fashion, sometimes I use RenderPartialView or RenderAction, etc.
By themselves they include tag. I would like to dynamically load either Views or ViewUserControl based on the selection in a dropdown list.
I'm having trouble deciding should I remove from Views and controls and put it just into the one View that will do dynamic rendering or to leave it there and leave outside of the .
What do you think and how would you go about it?
I would probably try to load the contents of a div after doing an AJAX call to get the contents. See the AJAX get call in the jQuery docs.
Or are the possibilities of what control to load so small you could just hide/show div's that are already in the page?
You can use JQuery to get the HTML from your Partial views and substitute it in the div. It could be something like this:
$.get('/Controller/Action',function(data){
$('div').innerHtml(data);
});
I did it this way and it works. /Controller/Action can be a partial view which returns HTML.
