Turn your Razor helpers into reusable libraries

2010-10-28T00:55:26Z

The first blog post I ever wrote was titled “ Turning an ascx user control into a redistributable custom control ”. It was almost exactly five years ago, and it still gets a lot of hits today. And interestingly, this new blog post is about solving essentially the same problem, but with a much nicer Razor based solution than was available at the time. The general issue we’re trying to solve is to encapsulate reusable pieces of UI. Unfortunately, this has typically meant choosing...(read more)

Light up your NuPacks with startup code and WebActivator

2010-10-11T08:52:42Z

Wow, it’s hard to believe that it’s been less than a week since NuPack went public. We were hoping to get noticed, but the attention we got was way beyond my wildest expectations! The buzz on Twitter has just been phenomenal, and for the most part the feedback has been very positive. Thank you all for that, this is very encouraging for our little NuPack team :) NuPack as a noun for the packages Before I get into the meat, I’ll just say that I want to start using NuPack...(read more)

T4MVC 2.6.20, and upcoming T4MVC talk at MvcConf

2010-07-20T07:28:11Z

I just pushed T4MVC out to the MvcContrib CodePlex site. You can go to the T4MVC Home Page to get started with it. Last time I blogged about a T4MVC release was for 2.6.13. In the mean time, I released 2.6.14 and 2.6.15, but they were minor updates so I just tweeted them. You can check out the history page to see what they changed. Now, 2.5.20 brings a more interesting new feature, so I figured I’d blog it. New feature to easily render Partials Update (7/20/2010) :...(read more)

Check out Chirpy, a very cool Add-In to run T4MVC and do many other cool things

2010-07-18T04:30:05Z

Just a quick post to point folks to a very cool CodePlex Add-In that you may not know about. It’s called Chirpy and can be downloaded from http://chirpy.codeplex.com/ . The reason I discovered it is that it includes functionality to automatically run T4MVC. In fact, it is basically the new version of the Add-In by Wayne Brantley that I blogged about a few months back. Wayne has been working on this with Evan Nagle , who is the main owner. But note that Chirpy does a lot more...(read more)

How WebMatrix, Razor, ASP.NET Web Pages and MVC fit together

2010-07-07T07:29:00Z

Today, we announced the public availability of the Microsoft WebMatrix Beta . This is an exciting time, as we’ve been working on this project for quite a while, and have been eager to get it out there! Our VP Scott Guthrie has been blogging about a number of its components in the last week or so, and you should definitely read through his posts to get a lot of information about it (start here ). In this post, I’d like to discuss how various pieces fit together, as I’ve seen some...(read more)

An even better way to run T4MVC: a VS AddIn

2010-03-18T21:43:41Z

Last week, I blogged about a nice way of auto-running T4MVC by using the Macro IDE to write an OnBuildBegin event handler . This was a big improvement over the hacky ‘AlwaysKeepTemplateDirty’ flag that we’ve been using since T4MVC’s early days. Since then, Wayne Brantley has taken this idea to the next level by turning it into a Visual Studio AddIn. Check out his post and give it a try! The nice benefits of the AddIn over directly handling VS events in the macro IDE are: Simpler install...(read more)

A better way to auto-run T4MVC when you build

2010-03-12T19:18:40Z

T4MVC has always struggled with finding the right way of running automatically when you build. Being a T4 template in your project, by default it just runs when you save it. This is not great, because you really want it to rerun whenever you make a change that affects it: e.g. new controller action, new static file, … So I had come up with a pretty crazy workaround (the AlwaysKeepTemplateDirty flag), described in details in this previous post (under “ The T4 file automatically runs whenever...(read more)

T4MVC 2.6.13: now officially in MvcContrib, with a few new features

2010-03-09T01:02:49Z

To get the latest build of T4MVC: Go to MvcContrib T4MVC page on CodePlex A few weeks back, we announced (mostly on Twitter) that T4MVC was moving into the MvcContrib Codeplex project. I didn’t say much about it at the time because there wasn’t a whole lot to say yet, in the sense that the move had not actually happened. MvcContrib was transitioning from github to Mercurial, and since I wasn’t familiar with either one, I figured I’d wait for that and only have to learn Mercurial...(read more)

Debugging ASP.NET generated code

2010-02-04T00:31:16Z

This post applies to any ASP.NET app that uses .aspx files, whether WebForms or MVC. When you write an aspx/ascx/master file (I’ll just say aspx for here on, but it applies to all), it gets compiled dynamically by the ASP.NET runtime. Note that this is true whether you use a Web Site or a Web Application Project (WAP). While in a WAP, most of the code is built by Visual Studio, the aspx pages themselves are always built dynamically . Normally, when you work with aspx files, you only need...(read more)

Take your MVC User Controls to the next level

2010-01-13T08:46:00Z

Note: this is based on ASP.NET MVC 2 RC , and will not work on earlier builds. The quick pitch: make your User Controls as cool as built-in render helpers! The goal of this post is to show you how to change the way MVC user controls are called from something like this: <%= Html.Partial("~/Views/Shared/gravatar.ascx", new { Email = "foo@bar.com", Size = 80 }) %> To something that looks just like a built-in render helper (like Html.TextBox(…)): <%= Html.Gravatar...(read more)

T4MVC 2.6.10: fluent route value API, shorter way to refer to action, and more

2010-01-05T02:45:36Z

To get the latest build of T4MVC: Go to T4MVC page on CodePlex I just posted build 2.6.10. There were also a few builds in between since I last blogged about 2.6, so this post describes some of those changes (full history here ). Fluent route value API As you probably know, T4MVC uses a pattern where the route values are encapsulated using a pseudo-call to a controller action, e.g. Html.ActionLink("Delete Dinner", MVC.Dinners.Delete(Model.DinnerID)) This adds the controller...(read more)

Passing anonymous objects to MVC views and accessing them using dynamic

2009-12-19T00:06:00Z

First, I’ll start with a little disclaimer: this post is not about whether using dynamic is better/worse than static typing. Instead, it’s about making it more convenient to use dynamic if you choose to go that route . Clearly, some people dislike dynamic, as you can see in the comments in that post from Phil Haack , and for the most part, all the key arguments for/against have been made. So anyway, let’s proceed… Recently, a few people have experimented with extending their view pages from ViewPage<dynamic>...(read more)

T4MVC 2.6: MVC 2 Areas support

2009-11-30T06:51:36Z

To get the latest build of T4MVC: Go to T4MVC page on CodePlex One of MVC 2's major new features is the support for breaking up a large application into "Areas". This works by following a structure that looks like: Root folder Models Views Controllers Areas NerdDinner Models Views Controllers Blog Models Views Controllers So basically you still have your top level Models/Views/Controllers folders, and in addition to that you can have an arbitrary number of “Areas”, each having...(read more)

T4MVC now has a real home and a dedicated forum!

2009-11-25T08:09:39Z

Up until now, most things related to T4MVC were happening through my various blog posts about it. And while that was sort of working ok for a while, it was also less than ideal for a couple reasons. First, there was no single place to go to in order to get information about it. You’d basically have to go through the various posts that describe the various features as they were added. And as the number of posts grew, so did the pain involved in doing that. The second issue is that...(read more)

T4MVC 2.5.01: added support for Html.RenderAction and Html.Action

2009-11-21T02:10:19Z

To get the latest build of T4MVC: Go to download page on CodePlex MVC 2 Beta introduces two nice helpers called Html.RenderAction and Html.Action. Phil Haack described them in detail on his blog , so you may want to read through that before reading this post. Basically, they’re two additional methods that follow the standard MVC pattern of passing the controller name and action name as literal strings, and the action parameters as anonymous objects. e.g. Copying from Phil’s example...(read more)
