As we all know, user input validation is one of the key concerns when developing various types of applications. Best practices and common sense suggest that validation rules should be kept as close to the business logic/domain model as possible. Fortunately, with the addition of Model Validation support with the Q2 2010 release of RadGrid and RadListView for ASP.NET AJAX, this is even easier than before. Please find attached a quick sample which illustrates this improvement in combination with RIA Services DomainValidator and DomainDataSource controls.     Have fun!...

Last time we talked about how to inject code at the beginning of a method. Today I will post how to inject code at the end of a method and I will cover some more complex scenarios as well. So lets start with sample program and then I will explain it in details. using System; using Telerik.CodeWeaver.Hook;   namespace ConsoleApplication2 {     sealed class MyClass     {         public void SayHello() { Console.WriteLine("Hello!"); }           public int SayHello(string name)         {             Console.WriteLine("Hello {0}!", LastName = name);             return (name ?? string.Empty).Length;         }           public string LastName { get; set; }           public int Increment10(ref int...

In June, Stephen Forte wrote a great blog post on Transparency and Software Teams.

Quality is a result of feedback cycles – the tighter the feedback cycles on your team, the more ability your team has to recognize issues and resolve them early. In fact, at Telerik we went so far as to try to have almost real-time transparency with the release of our free Project Dashboard tool that sits on top of Microsoft Team Foundation Server. Our goal was ...

The Q2 2010 release cannot do without several fresh additions and improvements in the WinForms toolbox. You can take a look at what the new version of the most widely used control in the toolset – RadGridView, has to offer. We’ve recognized the need to meet the endless demand for a supercharged, enterprise-oriented component that is able to work with large data sets and being flexible enough to perform operations like sorting, grouping, hierarchy and more, without sacrificing performance. Having that as a premise we have reworked our data grid so the end-users would enjoy a more robust and highly-optimized...

Yesterday a colleague of mine asked me a question about how to invoke a method of a base class' base class. Although it is possible it is not a good idea.
