It has been more than a year since the last time we discussed WebAPI with WebForms, and a lot has changed in that time. Microsoft has released a 1.0 release of WebAPI and Telerik now supports using WebAPI as a client-side datasource for many of our controls. In this article, I will show you how to configure WebAPI to work with one of Telerik’s most popular controls, our Grid for ASP.NET AJAX. Without changing the appearance of the grid, I will convert the grid from server-side databinding to client-side databinding and show you how it supports sorting, filtering and paging with WebAPI.

The Q1 2013 release of Telerik’s ASP.NET AJAX controls has been officially out for less than 24 hours, so let me brief you on the highlights: ...

I recently started reacquainting myself with the Telerik MVC Extensions, and it seems I had forgotten just how awesome they are! I want to talk about a few of the less known features I find really awesome in the extensions.

VS Extensions

Telerik’s MVC extensions come with built in Visual Studio extensions to make project creation, and configuration, a snap.  In addition, the extensions include a variety of project templates to help start new projects: 

 

What Makes it Awesome

Instead of forcing me to manually check for updates, the extension proactively alert me to any available updates:

When opening a project using an older...

Q3 2011 is knocking on the door and along with all the cool stuff you will find inside, there is one feature that we would like to tell you about now. Do you remember Excel-Like functionality, which allows the end-user to effortlessly apply filter by selecting items from a popup list? Now we are including a bunch of new stuff to it.

 

Calendar filter popup
First of all is a new calendar popup. It will be shown by default for date columns, and it will allow for easily selecting a date from RadCalendar. For additional convenience, there are a couple of predefined...

RadGridView provides numerous handful approaches to customize its appearance, even at runtime. For example, you could use formatting events or the Style property. However, sometimes it is handy to specify complex conditions in a script form. In our previous release we introduced an expression editor which allows for using formulas and expressions both at design time and runtime. In our next release we will introduce the same powerful feature for conditional formatting. You and your end-users will be able to target and style RadGridView cells and rows using powerful expressions.

With the help of our existing rule-based conditional formatting you can easily highlight all cells...

If you haven't heard, Odata is a Web protocol that exposes your data to the Web, allowing consumers to make queries through a set of URI parameters. RadGrid, Telerik's ASP.NET AJAX Grid control features a rich client-side API that enables you to easily bind to OData services and have all the paging, sorting and filtering done without ever posting the page to the server. That is all fine if your data is flat. Binding to hierarchical data, however, is another story. RadGrid officially supports hierarchical databinding on the server only. But let's go unofficial for a while. In this blog post we'll demonstrate an approach for detail table databinding...

This week we are about to release a private CTP of RadControls for WPF. We will be sending the CTP build to all people who have previously requested WPF controls. If you still haven't requested WPF controls from our support or sales folks don't hesitate to drop them a line and we'll send you a build.

If you're reading regularly the Telerik blogs may be you haven't missed Vassil's post about the Show Off videos which we prepared for MIX 08.
In case you've watched carefully the "Telerik Resort Explorer" video you probably are asking yourself at least a couple of questions:
1) Oh my! Telerik will...
