MVC 3 Razor Syntax - Partial View Menu.cshtml With Full Markup
Mar 27, 2011
This question appear when I worked with partial view (MVC3/Razor), but I am sure - it's clear Razor Syntax question, not related direct to partial view. So - I have partial view Menu.cshtml with full markup as:
@model IEnumerable<SportsStore.WebUI.Models.NavLink>
@foreach(var link in Model)
{
@Html.RouteLink(link.Text, link.RouteValues);
}
No problem - "parent" view call it @{Html.RenderAction("Menu", "Nav");} and all work as magic.
But, if I will edit the Menu.cshtml as:
@model IEnumerable<SportsStore.WebUI.Models.NavLink>
@foreach(var link in Model)
{
Html.RouteLink(link.Text, link.RouteValues);
}
(see - NO '@' before Html.RouteLink!) all just broke: now @{Html.RenderAction("Menu", "Nav");} output is totally empty, no one HTML tag. Want to know - what is the difference between two piece of code? I assume @ before foreach also automatically "drop into" and apply to Html.RouteLink as well? So - am I wrong?
While it has gnerally been advocated to separate code from mark up and all that, with the razor syntax and webmatrix all that is not valid anymore, I think. WebMatrix encourages code and mark up in the same page! So what is the best practice as far as code and mark up is concerned.
What is the best way to add javascript at runtime from a view (or partialview)? For example i would like to build a partial view Banner.cshtml that use Banner.Js. Actually i am using a section into layout page but obviusly if i use 3 times the same partial view i have 3 reference to external Js. Is there a "best practice" to include Js from "child" elemnts like partial view in this case?
I am working on a custom menu control, partially as a learning exercise, and I am having trouble with Visual Studio's IntelliSense support for it in markup view.The conventional ASP.NET menu allows you to place an arbitrary depth of <asp:MenuItem/> elements under the <Items>...</Items> element. I'm after the same behaviour for my menu.Mine unfortunately does not. VS insists on an empty tag:
In the default ASP.NET MVC 3 project, layout & partial cshtml files start with an underscore (eg. _viewstart, _Layout, _LogOnPartial). Why? Does the framework give some special meaning to a cshtml file that begins with an underscore?
In my application users can write their own 'templates'. That are filled with data from other sources. I could use a simple token replacement, but I would like to be able to use the Razor syntax and engine for rendering the template. Here is an overly simplified example:
[Code]....
Before you point to the following sources I will clarify what I have learned from them:RazorEngine (http://razorengine.codeplex.com/). This code compiles the string into a class, then a dll, then finally reads from a dll - all this to bypass the MVC engine. I don't want to do that because I am in MVC and don't want the additional overhead.The following blog shows how to do this for one of the MVC 3 pre-releases:http://buildstarted.com/2010/09/28/mvc-3-razor-view-engine-without-a-controller/ I cannot get it to work with MVC 3 RTM. When I take the exact code (and replace the CshtmlView with a RazorView) I end up with the error: The method or operation is not implemented. It appears to have something to do with @Model.Name, and being unable to find "Name".A comment in the blog elludes to a statement from ScottGu that the RTM would allow this functionality from the get go. I cannot find this blog.
For reporting we used report RDLCs and displayed using an ASPX form. We implemented using the route as shown below. This resulted in forcing us to use the page route below and also to use the hyperlink instead of the normal Action Link. The question is how do we convert the asp:hyperlink ASPX syntax to Razor syntax.
When I put a part of my form in a partial view, all form parts get unobstructive syntax except the form elements in the partial view. The only way I found how to "apply" the unobstructive syntax, is by starting another form inside the partial view.
<input class="text-box single-line" data-val="true" data-val-required="This field is required." id="Name" name="Name" type="text" value=""> <input id="SomeContent" name="SomeContent" type="text" value="0">
So only the input element from the View has the unobstructive syntax and the partial view hasn't... Is there a way to apply unobstructive syntax inside a partial view, wich doesn't require you to begin a new form?
I manage a large asp.net site which has previously been converted from static html site to asp.net. For several reasons (mainly SEO) we decided not to rename all the files to .aspx back when we originally converted the site. This was very easy to do by simply adding the buildProvider and httpHandler to the web.config.
Now I am upgrading the site to use Asp.net WebPages with Razor cshtml files. I can rename all the files if necessary, and use url rewriting to make the urls stay the same, however it would be much easier if I could just configure the web.config to tell it to parse .html files as if they were .cshtml. I have searched around quite a bit, and could not find anything equivalent to the PageHandlerFactory for razor pages. It appears as though it is just an internal mechanism in the .net 4.0 ISAPI handler.
The site is currently running on Windows 2003 server and IIS 6. We will be upgrading to 2008/IIS 7.5 in the near future, but I'd prefer not to wait for that. Is there any way to get the .html files to be parsed by razor as if they were .cshtml files?
How does one create a .cshtml page in an ASP.NET web application? The option to choose Razor is obvious when using MVC - it appears when adding a view. But I can't seem to figure out how to accomplish this in a plain ASP.NET Web Application. Is it even possible?
In Windows Forms I can create a class file called 'Authentication.cs' with the following code:
public class Authentication { public string Name; internal bool Authenticate() { bool i = false; if (Name == "Jason") { i = true; } return i; } }
In WebMatrix, I can insert a new Class file, called 'Authentication.cs', and insert the above code. And in my default.cshtml file, I do this:.........................
I download and installed the latest version of MVC3 from this website [URL]. The MVC3 framework works but not the syntax highlighter for Razor or intellisense. Anyone knows how to make this work? Just for your information, I could not install the vs10-kb2483190-x86.exe.
Check out the following: <a href="/test?x=@if (Model.IsTest) { @(1) } else { @(4) }"></a> Is there a better way to write this instead of the @(1) and @(4)?
I'm upgrading a regular asp.net project to asp.net mvc 3 (RC2) with Razor syntax. I got stuck now trying to figure out some way to create nested master pages. My main "layout" page contains the default header & footer. I used
[Code]....
When I now try to make a view page use the AuthLayout as a "layout" page:
[Code]...
Then I receive this error: The "RenderBody" method has not been called for layout page "~/Views/Shared/_AuthLayout.cshtml".
What is the appropriate way of rendering a child template?And what's the difference? Both seem to work for me.And why does @Html.RenderPartial() no longer work?
