Building AgiliTrain: Part 1 - Why ASP.NET MVC

Url: https://AgiliTrain.com

I've spent the better part of six weeks building the new AgiliTrain website and its been quite a lot of fun. Of course if you have been reading this blog for long you know that I usually take a personal project like this as an opportunity to learning something new.  In this case I did three things I haven't done on a personal project before:

When is a ASP.NET Project Not an MVC Project?

I am working on a hybrid ASP.NET MVC and MVC Dynamic Data project. To work on it I started with the MVC Dynamic Data project assuming this would be a Dynamic Data Project and an MVC project. As Scott Hanselman recently posted, you can mix and match pretty easily so the code was working but I was missing an important piece of functionality in Visual Studio:

Wildermuth.com By Example - Part 1

In response to some requests that I have received, I decided to write a several part blog on some of the techniques I used in developing Wildermuth.com. In this first example, I am going to discuss the use of LINQ and data in my site. 

In moving from www.adoguy.com to www.wildermuth.com, one of my goals was to use LINQ as much as possible to see the travails of using it on a real project. I have done a lot of small samples with LINQ but did it hold up for real work?  Suffice to say I am pretty impressed (though whether a blog is 'real work' is up for discussion, but its a better exercise of the technology than my samples had been).

Links and New Site Technology

Now that the change to Wildermuth.com is complete I've gotten questions about broken links and such. I am keeping adoguy.com around and redirecting (permanent) the links so that old links aren't going to break. I don't plan on keeping it forever but for several years you can be sure. Its worth keeping them around. 

I didn't just do a quick and dirty port to a new CSS look and feel though. This was a conversion of the old code. I don't use a blog engine but write my own code, mostly as a test bed for new ideas. What was it this time?  Two thinks significant changed: Entity Framework/LINQ as the data access and the ASP.NET Routing Framework instead of .aspx links. Let's take these one at a time:

Silverlight and Line of Business Applications

Url: https://www.livemeeting.com/cc/mseventsbmo/view...

In case you didn't catch it, I participated in a webcast called geekSpeak.  This webcast was hosted by Glen Gordon and Chad Brooks. The topic today was "Silverlight and Line of Business Applications". While geekSpeak's usually focus on hands-on examples of creating code, we took a different tact today and discussed the larger topic of where Silverlight fits in the development ecosystem (at least Microsoft's ecosystem).

Converting ASP.NET 2.0 to 3.5 for sites that use Silverlight 1.0

Quick fix for a problem that was haunting me today:

If you upgrade an ASP.NET 2.0 app to 3.5 and have .xaml files in your project that are part of a Silverlight 1.0 or 1.1 project, the conversion wizard converters them to Build-type: "Page" and adds a custom build for building the WPF files.  If this happens you'll get a cryptic error:

Behind the Scenes at ADOGuy.com - Part 1

I recently was talking with a prominent developer in the Microsoft community as they were creating a new version of their website. They had used a code generator to create most of the code on the new site which I thought was cool, but I immediately wanted to know how much functionality was included. As I talk with other MVP's as well as Regional Directors, it seems that I am in the distinct minority.  wildermuth.com is written almsot completely as custom ASP.NET code. Sure I used some components and started with someone else's HTML template, but most of the code is still C# to do much of the heavy lifting. Most of the people I talk with use community use pre-packaged systems to host their sites (including Community Server, DASBlog, etc.). 

Why do I keep all that custom code?  Mostly to allow me to try out new web techniques.  I am facinated by CSS and like to learn how different sites do what they do. I also like to add new technologies as I can (e.g. Silverlight, LLBGenPro) as I learn them.

Cookies Ruined the Breadcrumbs...

Trish and I are moving soon.  She's been sending me links to rugs for our new living room floor. She found an interesting one today:

New Website Look

I've reworked my web site. It was looking a bit more like the uniform of a NASCAR driver than a web site, so I reworked the layout to make it cleaner. I admittedly stole many of my ideas from other web sites and templates I saw.

The other reason for the change was to eliminate ViewState.  I noticed my pages ballooning from the sheer size of the HTML that was being generated, much of it as ViewState.  I've eliminated ViewState in almost every case.  For example, the size of the HTML of my home page was reduced from 134K to 48K.  That's just HTML size, not images...so the real size change should be even more dramatic.

ASP.NET AJAX RTM and WCF Do Not Play Well Together...

Url: http://ajax.asp.net/files/AspNet_AJAX_CTP_to_RC...

I am delving into WCF and AJAX (not at the same time) lately so I wanted to see if they were compatible.  According to this whitepaper on ASP.NET (follow the link and scroll down to "Support for WCF Web Services"), the RTM of AJAX does not support WCF.  It seems they removed it so they could make it work better in a later release.  The promise is that by the Orcas release of VS, they will be compatible.

SqlDataSource Issues...

Url: http://wilderminds.blob.core.windows.net/downloads/datasourcesgone...

I've blogged before about issues with the SqlDataSource.  I've crufted up an example of the problems that can be downloaded here (with usual caveat of changing the connection string in the web.config to point to a DB with the Northwind database).

ASP.NET Web Application...Wahoo!

Url: http://webproject.scottgu.com/Default.aspx

Big thanks to Scott Guthrie in championing the Web Application for ASP.NET 2.0!  I love using the old ASP.NET model (instead of the ackward Web Site project). I have now completely converted to the new format and I am very happy with the way it worked in almost every way.

Fritz Onion says Essential ASP.NET 2.0 Is Almost Done!

Url: http://pluralsight.com/blogs/fritz/archive/2006...

On Fritz Onion's blog, he mentions that the manuscript for Essential ASP.NET 2.0 should be done by Monday.  I am itching to get a copy of that book when it comes out.

ASP.NET 2.0 TreeView without Postback? Solved!

I've been scratching my head at the ASP.NET 2.0 TreeView control.  This control is meant to show a tree of items and each item can have a link to it.  For example, this is what I use for my menu on the left of the page. 

It works great, except I had a specific case where I wanted to use it.  I have a form for data entry where there is a hierarchy of items to select from.  The user picks an item from the tree view and I read the Path of the TreeView control and store it as the selected item.  This worked but everytime the user selected an item, I was getting a post-back to the server. It was as if   AutoPostback had been enabled.  But the TreeView control doesn’t have an AutoPostback property.  I noticed that if I set the node’s NavigateUrl property that clicking on a node didn’t call __DoPostBack, but instead called the URL I specified in the NavigateUrl property. So I decided to make the NavigateUrl property “javascript:void(0)”.  Essentially telling it that when the item is clicked, do nothing.

GridView, HyperLinkFIeld and FILE:// URLs

I was helping a friend out this evening trying to get a simple GridView working with a HyperLinkField from a database result and we ran into an interesting security feature that people might run into:

Lesson for the Day: Don't use XP Home for Development

As some of you know I lost the screen on my main laptop (HP ZD8000, a lovely machine at 13 lbs) so I sent it into support where they are going to fix it but take 2 weeks to do it. I took over my old laptop from my dear Tricia to try and make it work for a while.

To simplify her world, the laptop only had XP Home on it.  After getting the 3,000 things installed I needed to in order to work on my current project I am going to have to upgrade it to Professional.  The problem?  ASP.NET 2.0.

Web Application Project Preview from Scott Guthrie! (This is HUGE)

Url: http://webproject.scottgu.com/

This is freaking huge in my opinion.  It seems that all the fuss about how hard ASP.NET 2.0 has made it for many of us has gotten through to the team (yeah!).  You can download the Preview here:

ObjectDataSources Don't Work with Typed DataSets

Url: http://msdn.microsoft.com/newsgroups/default.as...

According to this post (this highlights my belief that MS is discouraging DataSets enough though they are using them everywhere (e.g. inside DataSources)).  SInce Typed DataSets don't work out of the box with ObjectDataSources, we are left with three uncomfortable solutions:

SqlDataSources Unusable if Tables Allow NULL's

 I've been working on a problem for a client's project.  We are doing pretty raw RAD design for a small intranet project so I thought, hey let's just do SqlDataSources to get the pages up and running fast.  This works fine *if* we don't want any concurrency. 

Let me repeat that, this works fine *if* we do not want concurrency.
