jQuery Tip #7 - Consolidating jQuery Ajax Calls

AddThis Social Bookmark Button
use of Ajax continues to grow in popularity it's worth taking the time to think through how Ajax calls are structured and used in an application especially if re-use and maintenance are important. If you analyze a lot of the Ajax code out there you'll likely find that calls to the server are scattered throughout scripts and pages. For example, if an Ajax call is made to get a list of jobs, a call is made directly in the script that needs the data. If another page/script needs the same type of data another Ajax call is made. This results...(Read whole news on source site)

Knockout anonymous templates and css3pie don’t get along.

AddThis Social Bookmark Button
I’m developing and ASP.Net MVC application with Knockout 2.0/2.1rc.  I’m using modernizr (2.5.3) and css3pie (1.0 beta 5) to get CSS3 and HTML5 support on as many browsers as I can. On a particular view I am using imageless add/delete buttons. I’m using Knockout to dynamically add and remove items from two tables. I had to use css3pie to help make the buttons work in IE 6-8 with this line for the add button: /* no fix currently for radial gradient in IE6-8... using linear instead.*/ -pie-background: linear-gradient(-90deg, #1b9918,#1b9918 65%,transparent 65%, transparent); and for the delete: -pie-background: linear-gradient(-90deg, #da7d83, #da7d83 50%,
#ca444e 50%, #ca444e); When I apply the binding in KO (.applybinding), the buttons disappeared in IE 8.  At first I thought something was wrong in modernizr but after some testing I realized it was only IE 8 that was failing.  That got me thinking about css3Pie. After some searching around on the internet I found this post. The final response gave me my answer: I have the same problem with a native ko templates, if I use "foreach"
without a container element. Also, I was trying to use PIE.js instead
of - but without success.

If there’s one thing the weekly updates are about, it’s beards, and it looks like that laser-like focus is finally paying off. But if there’s a second thing, I guess it would have to be keeping customers informed about what’s new and improved in the current nightly builds. Here’s what we’ve been busy on this [...]

EvenTiles and 256-MB Windows Phone Devices

AddThis Social Bookmark Button
source: In part 18 of the continuing story of EvenTiles we will take a look at targeting additional Windows Phone devices that will shortly hit the market in several countries. A few weeks ago, the Windows Phone 7.1.1 SDK Update became available for download. This SDK contains everything you need to develop Windows Phone applications that target the new 256-MB devices. Compared to Windows Phone 7.5 devices, these devices have less memory available, but they can run almost all applications that will run on Windows Phone 7.5 devices as long as they don't use
excessive amounts of memory and as long as they don't make use of generic background services. Even though the latter is no problem for most applications (especially since users might have disabled background processing for a particular application on Windows Phone 7.5 devices), in the case of EvenTiles this is kind of an interesting limitation. After all, EvenTiles was originally created to show you how to develop Windows Phone applications, but background processing became one of the more important features of the application. Having said that, EvenTiles will definitely run on 256-MB Windows Phone devices. The only exception is...(Read whole news on source site)

Memory Profiling - Launching, Graphs and Markers

AddThis Social Bookmark Button
source: windowsteamblog It is said that "A point of view is worth 80 IQ points"; the meaning perhaps being that if we can look at things in different ways then we might understand them better. The Memory Profiler that ships with the Windows Phone SDK 7.1 provides, in its own way, multiple views into the memory usage of your application, and in an earlier post we had seen how specific views helped us understand one particular issue with the application better. But even before we got to the specific views, there was a graph and a
couple of rows of markers, remember? Let us discuss them briefly. Launching the Memory Profiler How do you even know that you need to run your application scenario through the Memory Profiler, especially since there might not be any obvious visual cue? The answer lies in an Execution Profiler warning message. The expectation is that you would run your application scenario through the Execution Profiler for evaluating visual and code performance, and if it suspects any memory related issues it will raise a warning message suggesting running the scenario through the Memory Profiler! ...Read more
