Developers are using XML based RSS feeds and XML Web Services in their web applications on quite regular basis these days. ASP.NET version 1.1 was lacking built in capability to handle XML data that’s why ASP.NET version 2.0 is shipped with dedicated data source control called XmlDataSource. In this tutorial I will show you how you can use XmlDataSource control to handle and display XML data with very famous ASP.NET Repeater control. This tutorial will also show you how to bind XML elements with Repeater control using XPath binding expressions.http://www.ezzylearning.com/tutorial.aspx?tid=8462553Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTASP.NETNo matter how experience developer you are and how perfect code you write, sooner or later your code will be interrupted by a programming mistake, some invalid user input, wrong data or any other unexpected circumstances. No software can run free from error, and ASP.NET applications are no exception. In this tutorial, I will show you how you can do error handling in ASP.NET applications and how you can configure custom error pages with user friendly messages.http://www.ezzylearning.com/tutorial.aspx?tid=4245999Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTASP.NETWeb Services play an important role in data transport and communication between the client the server. Web services reside on the server and wait to be called by any client and most of the time these clients are written in server side technologies such as ASP.NET, PHP or JSP etc. ASP.NET AJAX provides web developers ability to call web services from the client side language such as JavaScript asynchronously to improve the user experience and to avoid full page refresh and postback. In this tutorial, I will show you how you can call an ASP.NET web service with the help of ASP.NET AJAX.http://www.ezzylearning.com/tutorial.aspx?tid=3967791Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTAJAXDisplaying Charts or Graphs has always been an important feature for reporting and both windows and web applications reports can be made productive for top management by visualizing data with the help of charts. Since the introduction of ASP.NET first version developers realized that there is no built in Chart control and they have to buy and use third party charting controls for their web applications. Many companies start providing high quality and feature rich commercial charting controls to developers. Finally ASP.NET developers received good news from Microsoft when a FREE ASP.NET Chart control is introduced and made available to developers as a separated download with hundreds of charts samples. In this tutorial I will show you how you can use ASP.NET chart control in your web applications.http://www.ezzylearning.com/tutorial.aspx?tid=4337488Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTASP.NETIn my first tutorial on ASP.NET AJAJX ModelPopupExtender control I have shown you how you can display model dialog boxes in ASP.NET with client side JavaScript behavior. In this tutorial, I will show you how you can use ModelPopupExtender control with server side post backs so that when user performs any action in the dialog box such as button click you can execute code in code behind file on the server.http://www.ezzylearning.com/tutorial.aspx?tid=6638633Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTAJAXModel dialog boxes are very common these days not only in Windows applications but also in web applications. They allow web developers to open new popup windows on the same page without creating a new web page. These popup windows typically ask user some input and temporarily disable the page unless the user dismisses the dialog box. ASP.NET developers can use ModelPopupExtender control available in ASP.NET AJAX controls toolkit to implement model dialog behavior in their web applications. In this tutorial, I will show you how you can use ModelPopupExtender control with client side behavior so that when user performs any action in the dialog box such as button click there is no post back to the server.http://www.ezzylearning.com/tutorial.aspx?tid=9142413Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTAJAXASP.NET AJAX Controls Toolkit provides many useful controls to ASP.NET developers to build modern rich internet applications. One such control is HoverMenu control that enables you to attach popup menu with any ASP.NET control. It can be used as a simple tooltip which can be attached with a TextBox and showing users what they are suppose to enter in the textbox or like many modern ecommerce shopping applications, it can be used to display larger image of the product when user move mouse on the product thumbnail image. In this tutorial, I will show you how to achieve this functionality using HoverMenu and GridView controls.http://www.ezzylearning.com/tutorial.aspx?tid=2693355Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTAJAXLINQ to SQL is one of the most widely used implementation of LINQ. It is so common that many developers completely overlooked other implementations of LINQ such as LINQ to DataSet or LINQ to Objects. Although LINQ to SQL is only available for SQL Server databases but it is still using all the features available in the other LINQ implementations. In this tutorial, I will give you brief introduction of LINQ to SQL, DataContext object, Entity classes and Object Relational Designer along with some simple LINQ to SQL queries.http://www.ezzylearning.com/tutorial.aspx?tid=1787244Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTLINQIn my first tutorial on LINQ, I have given you the overview of LINQ architecture, the query syntax and the Query Operators we use to build LINQ queries. In this tutorial you will learn one more important concept of LINQ called deferred query evaluation and I will explain you why it is important for writing high performance LINQ queries. I will also cover many deferred query operators available in LINQ.http://www.ezzylearning.com/tutorial.aspx?tid=4122562Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTLINQIf you are developing .NET applications from some time, you may already know how to connect databases and performs operations using either hard coded SQL queries or stored procedures. You may also know how to query the in memory collection of objects using traditional programming constructs such as loops and conditions. In this tutorial, I will give you introduction to Microsoft’s new technology called LINQ that enables you to integrate query processing features into your programming language such as C# or Visual Basic. More specifically I will show you how you can query in memory object collections or Arrays using some basic LINQ query operators.http://www.ezzylearning.com/tutorial.aspx?tid=8367792Waqas AnwarSun, 01 Aug 2010 09:30:47 GMTLINQ
