youve been HAACKED — Fri, 12 Mar 2010 00:00:00 GMT

Hot on the heels of the release of ASP.NET MVC 2 yesterday, Im happy to announce that we are releasing the source code to ASP.NET MVC 2 under the Ms-PL license, an OSI approved Open Source license. This continues the trend from nearly a year ago when we released ASP.NET MVC 1.0 under the Ms-PL. You can read my blog post there to learn more about the hard work that goes into such releases. While Im one who loves lawyer jokes, I do appreciate the work that they do (one of my best friends is a lawyer)...

Breaking changes from Q1 2010 Futures!!!

There is one breaking change since the Q1 2010 Futures release. The Toolbar method of the GridBuilder has been renamed to ToolBar:

<%= Html.Telerik().Grid(Model)
 //.Toolbar(commands => commands.Insert())  <- Old
        .ToolBar(commands => commands.Insert()) // <- New
%>

For a complete list of changed API of the grid check the changes and backward compatibility help topic.

By the way if you still havent cast your vote for a new product or feature do it now! We will soon start development for Q2 2010.

Improved appointment rendering in RadScheduler for ASP.NET AJAX, Q1 2010

the telerik blogs — Fri, 12 Mar 2010 00:00:00 GMT

Now that Q1 2010 release is out in the wild, we can sit down and discuss some of the changes we decided to make in the new release. One of them is the new appointment rendering of RadScheduler - a potentially breaking change, but a much needed one.

If you have problems with your old custom skins, include the old base stylesheet along with your RadScheduler and set EnableEmbeddedBaseStylesheet=false in your RadScheduler. You can find the said base stylesheet attached to this post.

While trying to improve the performance of RadScheduler, I noticed that the number of resources slows down the rendering and overall performance considerably. This had to be expected - the images to support the appointment rounded corners (and the predefined resources) were quite large. However, I didnt take into account that all browsers keep for performance reasons their images uncompressed in memory and with the color depth of the current desktop. A simple calculation later I discovered that the appointment sprite itself is taking 25MB memory when loaded. Add 5 resources to the fray and you have 150MB memory down with a single blow. As it turns out - a sprite image is not a panacea, if it gets too big - dont be afraid to break it in two. The loading time may suffer, but your browser suffers more while rendering a 25MB monster.

First I thought of undertaking the aforementioned solution - breaking the appointment sprite in two and thus reducing the two appointment sprites to mere 2MB uncompressed. Then I thought - the rounded corners are small - I can use borders and backgrounds to simulate rounded appointment borders while still keeping the same HTML structure. The gradients can be done with a single 10x50px image plus we have a gain - border colors and backgrounds can be changed on the fly.

I started with five rendering elements at first, then tried with four and finally I settled on only three elements. Behold the new appointment rendering (quite simple really):

On the left you can see that the first container has only top and bottom borders and a background. In fact, the background isnt even needed since it will be obscured by the elements on top of it. The whole first container is only needed for the four dots that reside in the four corners of the appointment. On top of this container is another one that holds the left and right borders and slightly lighter background to create the illusion of a second lighter border beside the other two. At last on top of all others is placed the text container that also holds the top and bottom borders and the gradient background. On the right you can see the final result - Im quite happy with it and I hope you will be too.

After creating the new rendering we took another step further - we decided to use alpha gradients for the resource rendering, thus supporting any color appointments with rounded corners and gradients. You can see some examples below:We plan on adding BorderColor and BackColor properties to the ResourceStyles definitions for Q1 SP1.

However with the new rendering in Q1 2010 we do support BackColor and BorderColor appointment properties - you only need to set AppointmentStyleMode=Default to keep RadScheduler from switching to Simple appointment rendering. Here is one screenshot of RadScheduler with appointments set to different colors:

I hope that you will enjoy working with the new appointments in RadScheduler.

Binding a select in a client template

More Whidbey stuff — Fri, 12 Mar 2010 00:00:00 GMT

I recently got a question on one of my client template posts asking me how to bind a select tags value to data in client templates. I was surprised not to find anything on the web addressing the problem, so I thought Id write a short post about it. It really is very simple once you know where to look. You just need to bind the value property of the select tag, like this: <select sys:value="{binding color}"> If you do it from markup like here, you just need to use the sys: prefix....

WebForms vs MVC (again)

Karl Seguin [MVP] — Thu, 11 Mar 2010 00:00:00 GMT

There's a new video up on www.asp.net which aims to help developers pick between ASP.NET WebForms and ASP.NET MVC. The video boils down to 5 benefits per technology which Microsoft thinks you should consider. Let's go over the points, shall we? First, ASP.NET WebForms: 1 - Familiar control and event base programming model The claim here is that the ASP.NET model is comfortable for WinForm programmers (thankfully this unbiased analysis left out who it's more familiar for). This is largely...

Determining Whether a String Is Contained Within a String Array (Case Insensitive)

Scott on Writing — Tue, 09 Mar 2010 00:00:00 GMT

About once every couple of months I need to write a bit of code that does one thing if a particular string is found within an array of strings and something else if it is not ignoring differences in case. For whatever reason, I never seem to remember the code snippet to accomplish this, so after spending 10 minutes of research today I thought I'd write it down here in an effort to help commit it to memory or, at the very least, serve as a quick place to find the answer when the need arises again.

So without further adieu, here it is:

Visual Basic Version:

If stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase) Then
    ...
Else
    ...
End If

C# Version:

if (stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase))
    ...
else
    ...

Without the StringComparer.OrdinalIgnoreCase the search will be case-sensitive. For more information on comparing strings, see: New Recommendations for Using Strings in Microsoft .NET 2.0.

Happy Programming!

PageMethods In ASP.NET AJAX

ASPAlliance.com - The #1 ASP.NET Community — Tue, 09 Mar 2010 00:00:00 GMT

Page Methods is a new mechanism in ASP.NET applications where the server code can be bound to ASP.NET pages. It is an easy way to communicate asynchronously with the server using ASP.NET AJAX technologies. It is an alternate to calling the page which is reliable and carries a low risk. It is basically used to expose the web methods to the client script.
