    RadControls for ASP.NET AJAX and validation

    Our good friend Peter Blum recently announced official support for our upcoming RadControls for ASP.NET AJAX (aka "Prometheus"). All customers that are using his Data Entry Suite will be able to integrate validation into the Telerik controls almost invisibly and without much pain and effort.    For those of you that are not familiar with Peter Blum, he is an ASP Insider and the author of the BEST set of validation controls on the market. I don't have any reservations to recommend his products as they are well done, very stable and very well documented.

    IE strikes again

    After the MIX announcement about IE8 I immediately downloaded the beta to check how RadGrid behaves. Unfortunately, it seems that TABLE elements are not fully implemented and this leads to a lot of issues. If you try to access table rows or tBodies you will get "Unexpected call to method or property access".   For some reason, some of the new properties are prefixed with "ie8_" and I am wondering when they will get an "ie9_" prefix.

    Web Resources demystified: Part 2

    “Why is my page sprinkled with links to webresource.axd?” By default RadControls (both “Classic” and “Prometheus”) utilize Web Resources to embed external files. By external files I mean the following: JavaScript files – they contain the code implementing the client-side features of the controls CSS files –they define the visual appearance of the controls Images –various GIF, JPG or PNG files used by the CSS files RadControls "Classic" embed all JavaScript files and the default skin (thoughtfully named "Default"). If you use any other skin or create your own it will be served from the location specified via the SkinsPath property ("~/RadControls/<ControlName>/Skins" by default). Reducing the number...

    Web Resources demystified: Part 1

    Every now and then I see people asking one of the following questions: “What is a web resource?” “Why is my page sprinkled with links to webresource.axd?” “Why are my JavaScript and CSS files not cached?!” “Why do all requests to webresource.axd fail with 404 or 500?” I will try to answer them in a series of blog posts. I will also give some details what web resources are, how they work and what are they good for. Web Resources 101 Web Resources are files which are embedded in an assembly. The WebResource.axd HTTP handler loads them and serves them to the browser. Web Resources were introduced in ASP.NET 2.0....

    Squeezing the last millisecond from the page load time

    Hi, my name is Erjan Gavalji. I am a developer in the ASP.NET division at Telerik. I am new to blogging, but I hope the topics I present will be of a real use. RadControls for ASP.NET provide rich client-side functionality and nice look trough a number of external files - JavaScript code and CSS definitions. Those resources are registered through <script> or <link> tags and are downloaded by the browser. Part of the client-side code in RadControls “Prometheus” is shared between all controls. It is contained in a different file to prevent downloading it multiple times when several controls coexist in a...
