I have been a developer for over 10 years, and at one point or another completely relied on the knowledge of someone with more experience than I had to make something work. I figure that it's time for me to start giving back. As background, I am a Microsoft technology based developer currently working in WCF/WPF/XAML, although I have only been doing this type of development for a little while now. I have a solid background that covers ASP.Net (C#/VB.Net), Traditional ASP, Javascript, custom AJAX ...
There is a new open source approach to Ajax architecting. The approach is called Empty Client. The name is derived from the fact that with this approach there is no logic, data or open service on the client and all Ajax calls are routed through a central HTTP/XML pipeline and optimized to a degree never realized on web before. The approach is implemented by Visual WebGui which positions the approach as Windows Over Web and cloud. The approach seems to get traction with Dot.Net developers, which use ...

After a lengthy break, the user group support kits from Microsoft have resumed. FedEx dropped off a big white box this morning, so if you are still awaiting yours... it should be there when you get home from work (or maybe in the next couple days.) User Group leaders didn't have the option of picking and choosing the contents for this cycle (or any future cycles, I would assume...) but don't fret, the contents are quite good. Assuming all the "Dev Group" kits are identical, this is what you can expect: ...
Welcome back. This time we will look at creating a simple jquery pager plugin to use with asp.net mvc project. Please note the intent is to learn the basics of jquery plugin development. The control as such is not recommended for use in production environment. I recommend having a look at the jQuery Authoring Guideline at docs.jquery.com/Plugins/Aut... Let's begin our journey into the mystery of jquery plugin. The first step is to create a self executing anonymous function. Anonymous functions ...
Let's try a simple in-place edit with jquery. For demonstration purpose I am using the plain old HTML file. However, if you, wish you could apply the same technique to asp.net, asp.net mvc or php or any other web application as well. Here is the html that we will be using for the demo. <body> <div style="line-height:3xm;back... Double Click the below paragraph to edit. </div> </br></br> <div class="edit"> Lorem ipsum dolor sit amet, consectetur ...
Just a decade and a half ago, the process of building a simple Windows-based application could have been described as a nightmare. The introduction of Visual Basic changed it so developers could for the first time implement Windows applications in an intuitive, graphical environment by dragging controls onto a form. The web revolution is here and now. Web had become very quickly the platform of choice for all kind of applications. The demand for web applications is ever growing and cloud computing ...
Recently my company just released the first version of a new MVC web site: AlbumCredits.com. This project, led by Oskar Austegard, is was I consider a highly successful real-world implementation of MVC. In a time when most music these days is downloaded, the production and performance engineers, and recording professionals that work on the music don’t always get credit because there is no CD booklet to look through. Album Credits is almost like a LinkedIn for recording professionals. From the about ...
This trick might work if you have an application that has been moved from the 2.0 framework to 3.5. This happened to me recently and I had tried removing the Web.Extensions reference and adding it back in, deleting old pages that had the older ScriptManager on them and manually removing then adding back the Web.Extensions sections in the web.config file. Nothing worked so I compared the web.config files from the problem project to one that was created from scratch targeting the 3.5 framework. I saw ...
It is Friday 13th Nov 2009 - which means it is the last day of TechEd Europe in Berlin. Overall I have had a good week – high quality sessions, lots of time with customers and colleagues and a very smooth conference throughout. I spent the week doing a bunch of things. 9am Monday I was presenting on Entity Framework 4 after 4 hours of sleep and using a brand new VPC after my original failed to load following yet another blue screen from the host (the machine will be flattened next week – perhaps ...

I was thinking of getting a new football jersey…here are some options. What do you think? Now before you all start making funny comments about how none of these apply to the Falcons (jerks ;) ), how about we focus on the words themselves. Why don’t we see jerseys like these? Don’t we want to show off our teams abilities and talents? Yes and no. When I go to a professional football game, I assume that the players know how to tackle, catch a ball, throw a block, run the ball, etc. I assume the coaches ...
I Just finished reading Learning jQuery 1.3 by Jonathan Chaffer and Karl Swedberg. This book provides a really indepth overview of jQuery along with many real world code samples. Its very well written and talks about all necessary topics from getting you started to Selectors, Events, Effects, DOM Manipulation, AJAX, Table Manipulation, Forms with Function, Shufflers and Rotators, Using Plugins etc. It also talks about advanced topics like extending jQuery and writing your own plugins and contributing ...

Today I was trying to call ASP.Net web service from JQuery. I thought it was easy first. But when tried implementing them I felt the difficulty. I don't had this problem while calling Ajax enabled WCF service from JQuery. Hence I did a small Bing and found out some useful tips to share. I referred links below. http://www.mikesdotnetting.... http://www.dotnetcurry.com/... http://encosia.com/2008/03/... ...
This series is going to document increasingly complex usages of the jQuery UI Dialog widget. This first part of the series will demonstrate how to display the default dialog.

It is quite common to display a loader-image or some kind of progress bar image in a browser when the server is busy serving the request. Before we go deep into page streaming techniques with XMLHTTPRequest call and IFrame, lets look into a simple loader icon implementation – the idea is to display “loading” image until the task completes, display the response in the browser when task ends and hide the loader image. to download the source code please click here Invoke a long task and display loader ...
to download the source code please click here In the earlier post we have discussed little bit about the limited number of worker threads available in the thread pool of ASP.NET and we identified why we should always try to avoid to block those important worker threads. ASP.NET 2.0 introduces Asyn=”true” attribute in the page to handle asynchronous scenarios and under the hood this attribute tells ASP.NET to implement IHttpAsyncHandler in the page. There are more than one ways available in ASP.NET ...
As an ASP.NET developer we frequently deal with long running tasks for example: Making long-lasting webservice calls. Making prolonged calls to database that runs complex queries. Do lengthy file operation Calling remote objects etc. When the server is busy performing the lengthy time consuming task/tasks, the poor user has to wait for the response. The most common technique used to interact with user is to display a loader icon or show some kind of progress bar on the page until the task is complete. ...
So you are going to an event with 7,000 people that have similar interests to learn about a product that you have a vague idea about…I was excited prior to the event and nervous. I had a very bad week before the event. Every piece of technology that I brought with me to St. Louis broke. I had little sleep trying to get my code done and my technology to the point I started out with that Monday. Finally by Friday I was beat and hung out with my friends…On Saturday I went to Coders and everything after ...

Visual Studio 2010 Beta 2 is out and has a slick new UI. Also, this Beta has most of the features that would ship with the final version compared to the earlier Beta. Note that while new features might be added, there are chances that some of the features demonstrated here may also not be a part of the final release. But, for now, lets examine the current Beta 2. The first thing you would notice and probably like, is the UI enhancements. Herebelow, is the launch screen. Also, the start page has been ...

After the keynote sessions and lunch the first set of breakout sessions kicked off. Needless to say with the session line up it was difficult to choose only one to attend. However I thought it would be wise to at least see what is new and get an overview of the platform. I got to the session a bit late, but I don't think that I missed much. Arpan Shah was the speaker and it was a packed house. One of the largest rooms I have seen so far. Easily over 300 people in attendance. Here is what I caught. ...
Imagine some newbie or junior web developer walks up to you and says, “What tools would you suggest I use to become a better web developer?” Assuming they’re already using either Visual Studio or Web Developer Express, what utilities or resources do you find indispensible for working with ASP.NET or just web development in general? Maybe you have a favorite online resource site that you recommend, Stack Overflow for example, or maybe you have a favorite utility like Chris Pederick’s Web Developer ...
I can't believe how long this took to figure out, I think I read every WCF tutorial out there, and now I look at it it's so mind bogglingly simple I don't know what I wasted my time doing! All I wanted was a WCF service that would accept a POST from jQuery with some JSON parameters and return some HTML, but it seems I repeatedly cocked up the JSON string format and the attributes for the contract. Anyway, here's a simple example so you don't have to endure my frustration. I used .NET 4.0 because ...

The latest version of Ra-Ajax, 2.0.3, was released last night. This release has a couple of important bug fixes and a new Effect called EffectCssClass. This new effect was contributed by Karel Boek. EffectCssClass simply allows you to change the CSS class of a widget easily when doing chained and/or joined effects, like this: new EffectFadeIn(panel1, 500).ChainThese( new EffectHighlight(panel1, 700), new EffectCssClass(panel1, "className"), new EffectRollUp(panel1, 1000)) .Render(); Ra-Ajax version ...
This podcast accompanies the October 8th edition of the MSDN Flash newsletter. It is an interview with Paul Jackson which is meant to be about the article he wrote on Memory Mapped Files in .NET Framework 4.0 but tends to go off in different directions – but we both certainly enjoyed doing it :-) I was interested to hear how he was getting on with Oslo and why he was revisiting ASP.NET after many years of focus on XAML.

If you dont want to use strings but instead use strongly typed expression syntax in ASP.NET MVC, you can use the HtmlHelper<TModel> and AjaxHelper<TModel> types that are exposed on the ViewPage<TModel> base class. You can then write syntax like <ul> <%foreach (Product p in ViewData.Model.Products) { %> <li> <%=Html.ActionLink<Ca... %> </li> <%} %> </ul> instead of <ul> <%foreach ...
Earlier, I had written this post on how you can accomplish using FileUpload control in UpdatePanel since by default it wasn’t supported. The post seems to have helped many and keeps being the most visited one. However, with the new release of Ajax Control Toolkit (v 3.0.30930) released specifically for .NET 3.5 SP1 (with Visual Studio 2008 SP1), there are couple of new controls. One of them is the AsyncFileUpload control. Thanks to the codeplex community which keeps getting better and better with ...
This Saturday (October 3) I’ll be presenting at Richmond Code Camp. Registration is still open. I will be presenting “MVC in the Real World” – Move beyond MVC 101 and dive into aspects of building robust, real-world MVC applications. This demo-heavy presentation will show how to fully unit test the presentation layer with mocking and Dependency Injection. This session will show the benefits of using Inversion of Control (IoC) containers to create controllers with a custom controller factory. In addition ...
I needed to get a pop-up window to come up in ASP.Net. Now while JavaScript happily does this (with the alert(); function ASP.Net does not. So I needed to work out how to do it. Another wrinkle in this comes from Ajax. None of the JavaScript code seemed to work when placed in an AJAX page. As I have now been tasked with changing this code and moving from the Anthem Ajax library to a pure MS solution it was time for this died in the wool VB/C# developer to get his head around getting these scripts ...

What a pity. I’ve spent some time recently evaluating SQL Server 2008 Reporting Services with respect to its proposed use on a UK public sector project that will implement a part of the 'national infrastructure'. In every respect but one, Reporting Services provides an excellent fit for the stated requirements. There is already a commitment to using SQL Server, and SharePoint, within the project, so Reporting Services appears the way to go. What is the exception? Well, Reporting Services provides ...

I have been developing asp code for quite some time now. I started out with interdev 1.0 way back when. From what I can see we have seen 3 major revisions of ASP. Classic ASP Archiac to say the least but hindsight is always 20-20. Great intro into web development, we started n-tier development here, most sights were done in a 2 tier environment, and at the end of its lifetime we started developing 3 tier environments with SOAP.

For many customers the ROI on software licences is one of the key factors when purchasing software, so when deploying an e-Commerce solution the level of return for frameworks, and CMS platforms such as Commerce Server and MOSS are quite justifiable, however it is the extra features – such as the Store Locator that is difficult spending licensing money on. The current store locator within CS 2009 is based on a commercial Microsoft Virtual Earth web-service, which is provided for non-developer used ...

Scenario: The user wants to save something and hits the Save button (type=submit). The event performs an Ajax call to send the request to the server. The user, being unaware or not sure if their request is being processed or if they clicked the Save button properly, click it again, and again, causing several Ajax requests, which could be a real problem, if the update is to, for example, transfer funds to your ex-girlfriend's account The solution: Prevent the user from being able to click the Save ...
I had looked up the LoadControl(“”) method earlier today, and came upon a short website entry that quickly discussed how to load a web user control (.ascx) dynamically onto a page. The link is: http://www.codeproject.com/... It mentioned inside that a CMS (content management system) could be built using this method + a database table to track these controls. It got me intrigued, so I decided to pursue it. It’s pretty simple, and actually adds a lot of cool functionality ...
