    ASP.NET Ajax Controls and jQuery IntelliSense - UPDATE

    Starting from the Q3 '08 release, the jQuery library is an integral part of RadControls for ASP.NET AJAX. We've posted instructions on how to use the included version in your code and how to enable IntelliSense. The bad news is that the instructions for enabling IntelliSense no longer work with the Q1 '09 version. The reason is that Visual Studio 2008 has a problem with parsing the jQuery library from version 1.3 and up. This required us to come up with a new way to enable IntelliSense. The good news is that the new approach is much cleaner and doesn't require external...

    XML DataSource - General information

    The XmlDataSource control is a data source control that presents XML data to data-bound controls. The XmlDataSource control can be used by data-bound controls to display both hierarchical and tabular data. The XmlDataSource control is typically used to display hierarchical XML data in read-only scenarios. Because the XmlDataSource control extends the HierarchicalDataSourceControl class, it works with hierarchical data. The XmlDataSource control also implements the IDataSource interface and works with tabular, or list-style, data.  Page developers use the XmlDataSource control to display XML data using data-bound controls. The XmlDataSource typically loads XML data from an XML file, which is specified by the DataFile property. XML data can also be stored directly...

    JavaScript - Variables and Types Basics

    This article is taken from JavaScript @ Wikibooks. JavaScript is a loosely typed language, this means that you don’t have to worry about setting the type of variable and you can change at will in runtime. But when you code, you have to make sure that you are getting the right type at the right time. Variable declaration Variables are commonly explicitly declared the var statement, as shown below: var c; .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The above variable is created, but has the default value of undefined. To be of value, the variable needs to be initialized: var c = 0; Variables can also be created by assigning directly to them,...
