Nick Symmonds works for the Integrated System Solutions division of Ingersoll-Rand, developing and integrating security software.He started his professional life as an electronics technician. Nick has written several articles on programming and has three books out: Internationalization and Localization Using Microsoft . NET (Apress, 2002), and Data Entry and Validation with C# and VB . He lives with his family in the northwest hills of Connecticut and has recently become addicted to golf and road cycling.In the following tutorial we will demonstrate how to use a validation panel together with Error provider. For the purpose of this tutorial, we will create a new class Employee with a couple of exposed properties. Data Layout Item Validated Event Args) Dim employee As Employee = Try Cast(Me. By binding Rad Data Layout to object from this type we will generate several items: _ Public Property Last Name() As String Get Return m_Last Name End Get Set(value As String) m_Last Name = value End Set End Property Private m_Last Name As String Public Property Occupation() As String Get Return m_Occupation End Get Set(value As String) m_Occupation = value End Set End Property Private m_Occupation As String Public Property Salary() As Integer Get Return m_Salary End Get Set(value As Integer) m_Salary = value End Set End Property Private m_Salary As Integer Public Property Starting Date() As Date Time Get Return m_Starting Date End Get Set(value As Date Time) m_Starting Date = value End Set End Property Private m_Starting Date As Date Time Public Property Is Married() As Boolean Get Return m_Is Married End Get Set(value As Boolean) m_Is Married = value End Set End Property Private m_Is Married As Boolean End Class Private Sub rad Data Layout1_Item Validated(sender As Object, e As Telerik. NET supports eight different e-mail address verification levels and allows you to configure every possible aspect of the validation process, including adherence to IETF standards preferences, network-related settings, timeouts for multi-threaded activities and even your own custom validation rules, embedded into the main email verification pipeline. Parse("8.8.8.8")); // Pass the configured settings to the verification engine var result = engine. Furthermore, the component exposes dedicated methods and structures to track down and configure each verification activity that may take place in every asynchronous scenario at optimal performance.In the following snippet, for example, Email Verify for . In the following snippet, for example, Email Verify for .Such measures involve the application of to any data being input to the program.Any input not meeting the program's requirements (i.e.

These events may be used to track down the overall progress of a given set of multiple addresses, for example, and possibly feed a user interface element of your project, like such as a progress bar or a list of messages. It validates any address you give it against IETF standards (RFC 1123, RFC 2821, RFC 2822, RFC 3490, RFC 3696, RFC 4291, RFC 5321, RFC 5322 and RFC 5336, among others), thus guaranteeing its syntactical validity.

While getting his bachelor's degree in electrical engineering from the University of Hartford, he started to gravitate toward programming. He also enjoys woodworking, hiking, and exploring the hills on his motorcycle. This book is not only briliantly written, but it provides a clarity that i have yet to find elsewhere in my extensive library of collective knowledge.

Nick has spent quite a few years programming in assembly, C, C , and Visual Basic. Sparing the few moments of your life that it takes to read this invigorating and rivetting book will save you time and energy searching across the web for such relevant information.

This is definitely a masterpiece and will be sure to advance your career exponentially, without question.

This should be required reading for anyone who designs interfaces.
