Use Ajax For Cascading Dropdown List

<div> 				Cascading dropdown with Asp.Net AJAX ToolkitCascading dropdown can be programmed in the ASP.net in various ways. However I am planning to design my application in a highly performance based approach. For reading data web server to client I am planning to use Web Service. So the data transfer between server and client is very minimal without the bulky HTTP response with lots of HTML tags. By this you can feel the cascading very fast.Since this article requires Ajax Control kit. It needs to be downloaded separately.Once downloaded, create a new website and select the DEFAULT.ASPX and then switch to design mode in the Web FormIn Web FormWhile in design mode, open the tool box and right click and choose items. In the "Choose Toolbox Item" choose the downloaded AjaxControlToolKit.dll.Add Cascading Dropdown to the Web form from the tool box.Add a web service named NorthwindDataService.asmxIn Web Serviceimport Ajax Control ToolkitAdd a new function named as Get Categories with the following parametersCascadingDropDownNameValue: Ajax control kit requires this object back for loading data [name should be kept as it is]Category: The category for filtering data [name should be kept as it is]Next step is to get data from DBimport System.Data using Imports System.Data in the topimport System.Data.SqlClient alsoNow get a Data Reader to fill up the CascadingDropDownNameValue list.Now its time to fill up the Cascading Dropdown control with the web service and web method we created just now.Fill up the followingServicePath="NorthwindDataService.asmx"ServiceMethod="GetCategories"Category="CategoryName"If you are running the website now, the first dropdown should be loaded with data now. If you are getting any errors like error 500 or method error 12031, The chances are there are few lines might be missed outAfter this change, start running the website. It should compile and run. If you select the first dropdown it should return the list of categories. If you are not getting any output you may try running the web service in browser by 'set as start page' on the web service. The logic is to make sure the web service is working as expected and returning the list of categoriesFor the second drop down the only difference you are going to do is, passing a parameter to filter the data based on the first parameter.To get the parameter from the selected item of the first DropDownList Dim Param As StringDictionaryParam = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues)Then the Param Dictionary will contain the data we need. We can easily fetch the value from the name value pair like Param ("CategoryName"). Use that in the select query to fetch filtered record(For complete source code please refer <a href="http://www.vbknowledgebase.com/?Id=104&Desc=JavaScript-Ajax-Cascading-Dropdown" rel="nofollow" target="_new">Cascading DropDown</a> )			</div>

5 Reasons Why Some Developers Prefer Developing ASP Dot NET Applications

<div> 				Comparing two distinctly different programming languages or even two closely associated languages is definitely an exercise in futility. The reasons are simple, why compare French to English or PHP to Ruby, as people differ in their tastes, so do their choices too. In view of this, instead of focusing why X is superior to Y, I will try and focus on why some developers are more comfortable using ASP.NET as compared to competing platforms. That said, the fact that any platform continues to exist and is used by people in the field of IT, means it has at least some features, which cannot be availed using competing services. Following are the leading reasons why some developers choose to use ASP.NET for application development:HTML5 Support and Web APIThe new versions of ASP.NET from version 4.5 onwards provide developers with enhanced support for various form types specific to HTML5 such as color, search, date pickers, range, number, URL etc. Earlier many of these forms were created / designed separately prior to being integrated into an application. This support generates substantial time savings for the developer and by extension the software development company. The enhanced support is extended to the availability of Web API along with the standard ASP.NET Web Forms and ASP.NET MVC 4 package. At the very least, the Web API aids developers in simply building Web-based services/applications, while users find it easier to use online resources, while using the applications.Security Provided By HTML5 WebSockets and OpenID SupportFrom version 4.5 onwards, developers can access advanced security features including HTML5 WebSockets. By using WebSockets, developers can ensure duplex communication between the web server and the client's browser. It is also possible to leverage the feature, while designing Web applications. However, availability of Visual Studio 11 is mandatory to avail this specific functionality while designing ASP.NET applications. Additional security is also available through OpenID support, which can be used with OAuth Login suitable for various.NET applications.Asynchronous Programming Support and the New GridView ControlRecently introduced versions of.NET features support for asynchronous programming, which allows developers to read as well as write HTTP queries and requests without using OS threads. GridView Control has been a key tool of ASP.NET since the first versions were introduced decades back. In recently years, this tool has been substantially improved and the GridView Control featured in version 4.5 allows developers to easily perform tasks such as efficient sorting and paging of large data sets.Unique Model Binding Properties and Value ProvidersNew versions of the framework feature unique model binding properties, which allow developers to isolate specific web forms from the model and/or binding them according to the user's requirements. This feature aids the development of Webforms independently from the model as well as unit testing each form separately. This facility reduces the chances of even small errors creeping into the final application and generates significant saving of both time and money for the software development company. The new-age Value Providers featured in recent.NET versions helps developers easily filter large data sets by using commands such as control value, cookie, session, querystring etc. Moreover, developers are free to develop their own Value Providers to enhance the filtering procedure.Bundling and Minification OperationsThis is one of the relatively new features in.NET 4.5, which is designed to minimize and bundle the size of style sheets and scripts utilized while developing an application. This feature improves the overall efficacy of the application by ensuring that the codes are easy to read, which helps minimize as well as resolves coding errors. The features are easily noticeable in a new project by viewing the coding of the Global.asax file. The factors discussed here barely scratch of surface, but hopefully they would help you understand why ASP.NET continues to dominate such a competitive market.			</div>

10 Mistakes Every Net Developer Would Regret

<div> 				Admit it! We all make mistakes. None of our codes starts working at strike one. We make typos, forget signing off or, as it happens with most of us, overlook the testing phase, especially when it comes to ASP.net development. To err is human. So, making mistakes is just another human phenomenon. What counts is how you tackle your errors and how you devise ways to avoid them in the ventures to come. Here's a compilation of some of the most common testing mistakes that developers often commit while catering to outsource .Net development needs. Let's take a look.XSS Security Issues: The look and feel of your UI and of course, its maintenance lies in your hands. Ensure that all user-input fields are well-customized so that no JavaScript or HTML that a user enters can rummage your web page.Universal Localization: As a usual norm, as you begin developing a new feature, you keep all the text in hard code as there are probabilities of certain changes during the course of development. As soon as the project team approves the feature, you localize the text. However, at times you tend to forget localizations of the entire text. You remember to hard code, but when it comes to localization you tend to sign off without doing the same. Probably this checklist reminds us to localize before we sign off the next time..Net Behaves Well with IE 6 and 7 and Firefox: Test leads often report of cross-browser compatibility issues that crop up from time to time. Most of these issues usually encompass small twigs like usual IE 6 issues or minor problems relating to positioning of elements. We are dedicatedly focusing on IE version 6 and 7 and Mozilla Firefox for two reasons. Firstly, if your web page works well in these three browsers, it will function well on Opera and Safari as well. Secondly, over 98% of the visitors access your site through these browsers.Reuse Code as and when required: This law is applicable across all programming platforms and ASP.Net is no exception. Separate server and user-control elements enable specialization of code so that it can be used at other places as well.Commenting on the Code: There are no two-ways to this. Always document your code well and comment upon the right places, so that it is easier for other developers to pick up from where you left.Extended Text doesn't Mean Broken Design: As a matter of fact, names usually don't extend beyond 50 characters, but what if some user inputs a name containing 300 or even more characters. Obviously, in that case the UI will be disrupted. In this case you have two options- either codes your interface to accept long text inputs or put a limit on the length of text users can input.Write Units When Possible: Unit testing for your website can be a tedious job especially if you are not using ASP.Net MVC framework for the same. However, pulling the code-behind logic into different components that can be placed in the library can enable you to test the units. Instead of dealing with HttpHandlers using .ashx files, placing them in separate libraries is a good option.Peer Verification before Testing: Before signing off any newly added feature and sending it across to the test team, you usually pass it through peer verification. As the name suggests, in peer verification, one of your colleagues tests the application feature you have just developed and tries to find flaws in it. This allows you to identify errors easily and also simplifies the process for the testing team. When schedules are really tight, we often forget to ask for peer verification and it definitely shows at the end.Expected functioning of Enter-key: When you are using webforms in ASP.Net, the enter-key often starts functioning weirdly. In this case, you can either set default buttons on the Panel webcontrol or from code-behind.Sign Off by Product Owner: By default, the ownership of a product feature lies with the product team. Developers also have a share in ownership but that is only until the implementation level. Often when you have too much to handle, you forget to get a sign off from product owner. If the owner doesn't sign off your work it means you haven't completed it, even if you have already marked it as done. This is frustrating and can extend deadlines.The aforementioned mistakes are common and can be made by any developer. If you are an Asp.net developer, these mistakes should be taken care of in the next development venture. If you are a business owner and looking to hire .net developers, then ensure that your developers take care of the same while developing your web application.			</div>
