Perform Remote Validation in ASP.NET Core
While performing model validation, at times you need to validate values entered in client side controls against server side data. Such a validation is called remote validation. As you might have guessed remote validation uses Ajax to validate the data. Thus validation is initiated on the client side but performed on the server side. The outcome of the validation process is sent back to the client so that the end user can be notified accordingly. In this article we will learn to implement remote validations in ASP.NET Core MVC and ASP.NET Core Razor Pages.

Pro .NET 2.0 XML
(APress, April 2007)


XML is the de facto language for communication within and between distributed applications, whether they are on the Internet or a corporate network. XML is successful because of two strengths: it has a highly-structured human readable format and it can be transmitted as pure text. No matter how disparate applications and their architectures may be, text files can always be read, and therefore can accept XML data. This makes XML-based solutions advantageous over rival technologies like remoting. Pro .NET 2.0 XML is the first book to provide a complete solution to XML on the .NET Framework 2.0 including the new .NET 3.0 extensions that are being released in January 2007. It provides you with everything you need to know to take advantage of XML in every aspect of your job including integration with Windows Communication Foundation.

Developer's Guide to ASP.NET 2.0
(BinaryIntellect Consulting, November 2005)


Since Microsoft introduced ASP.NET the overall web application development is revolving around ASP.NET as far as Microsoft product based solutions are concerned. ASP.NET brought a major shift in the way applications are built and deployed. Web applications suddenly became so rich and powerful! Continuing the same wave further Microsoft has introduced ASP.NET 2.0. The new version is totally backward compatible with ASP.NET 1.x. However, it introduces some major enhancements and additions. While building version 2.0 the goal of ASP.NET team within Microsoft has been to reduce the amount of code that developers are writing today to a great degree. Version 2.0 brings more than 40 new controls and provides many new classes and concepts. With these additions ASP.NET 2.0 is poised to be stronger, flexible and powerful than ever before. This book is about ASP.NET 2.0. It teaches you most of the concepts that you need to make yourself up and running with ASP.NET 2.0. There are books that cover just the new additions to ASP.NET infrastructure. This book is different. It looks at ASP.NET 2.0 as a complete platform for web application development. You will find many topics that are equally applicable in ASP.NET 1.x also. Care has been taken that you need not refer to any 1.x book for understanding the concepts.

Professional XML for .NET Developers
(WROX Press, December 2001)

XML is now an established technology for the description and transportation of data, and has made a major impact on almost every aspect of software development. When Microsoft introduced the .NET Framework, they took advantage of XML wherever they could. No other technology is so tightly bound with .NET as XML, both at the developer level and underlying the whole framework. This book aims to give the reader enough information to be able to use XML from within the .NET Framework in the most efficient manner possible. It will explain in detail the usage of all the XML-related .NET Framework library classes for the manipulation, validation, transformation, and serialization of XML data, using both C# and Visual Basic .NET. It also looks at how the developer can utilize the full power of XML within the .NET Framework, for example, with the new XML capabilities of ADO.NET and ASP.NET. As is demonstrated, the .NET Framework itself uses XML, in configuration files, meta data, and C#'s XML code documentation mechanism, for example. This book is aimed at intermediate-level programmers who have started on their journey towards .NET development, and who want to see how to use XML within their applications to its best advantage. Basic knowledge of C# or Visual Basic .NET, XML, and XML related technologies (XSLT, XPath, and XML Schemas) is necessary.
