Web: ASP.NET AJAX

This is the second module in the ongoing course HTML5 Development For ASP.NET Developers. This module will cover how to create a RESTful service with ASP.NET WebAPI, and how to consume that service in JSON format with jQuery. There is also a very quick primer on the...

JSON (JavaScript Object Notation) is the way to handle data on the client these days. It really is the cat’s pajamas. Almost all the client-side widgets or libraries that you’ll be working with will most likely be utilizing JSON, and sending large chunks of data over the wire as JSON as opposed to other bulky forms of data can lead to some dramatic performance increase across any application. I often come across individuals not sure of what JSON is, or how they can use it today, and I wanted to address this issue in a blog post. Of course I...

In my last blog I introduced the basics of using ASP.NET AJAX and WebAPI together in the same project.  In addition, I showed how to bind results from WebAPI to a Telerik’s ASP.NET AJAX Grid. In this blog I will continue down this path and implement insert, update, and delete operations using WebAPI and RadGrid! Note: While this post focuses on using WebAPI in conjunction with RadGrid, most of the client code can be used when working with RadGrid in client mode.Set It Up! To get started an additional reference needs to be added to the project: System.Net.Http.Formatting Adding this reference allows us...

There’s a ton of cool stuff coming out with ASP.NET 4.5 and Visual Studio 11. If you haven’t had a chance yet, take a look at my top five list of Visual Studio 11 Designer improvements for ASP.NET 4.5 development, as well as my deeper dive into the VS11 Page Inspector tool. Today however, I want to jump a bit more into code since, so far I haven’t covered too much of that! One of the new ASP.NET 4.5 improvements I’m excited about is the ability to have strongly typed controls. That’s right, you heard me, strongly typed! Why am I so...

Lately we’ve been receiving one question quite often - is it possible to increase the RadButton and / or RadFormDecorator’s button default height. Usually people are trying to set the needed value to the Height property: <telerik:RadFormDecorator runat="server" DecoratedControls="All" /> <asp:Button runat="server" Text="RadForm Button" Height="40" /> <telerik:RadButton runat="server" Text="RadButton" Height="40"> </telerik:RadButton>   But the result is not pretty:      By default the RadButton as well as ASP Buttons and inputs of type=”button” decorated by the RadFormDecorator are visually built with sprite images that apply a specific gradient to the element. The sprite image has a specific height, which means you cannot just change the button’s height property because the sprite image will be either cut off or...
