It has been a while since we introduced the initial version of the OData binding API for our controls. Despite providing robust OData binding, the old API had one major drawback – it was tedious to configure. A lot of markup was required and there was no design time in order to make developers life easier. Well, this is no longer! I am glad to announce that with Q2 2012 we are shipping our newly baked ODataDataSource control which is intended to replace the old API and provide more robust and straightforward way to consume OData services.

Visual OData Binding

 Its goal...

In the previous series of OData binding related posts we introduced OData support for our Grid, ListView and navigation controls. Well, it is time for a new control to utilize such binding. I am happy to announce that forth from Q2 2012 one can easily bind the Telerik's ASP.NET Ajax Scheduler to OData exposed feed using simple markup.

Why OData

One may ask why OData when it is possible to expose AppointmentData objects via simple ASMX/WCF service and have the Scheduler directly bound? Well, the OData binding gives you the freedom to bind against any JSON structure, as long as the core scheduler Data...

As a follow up to the webinar hosted by our colleague Carl Bergenhem "Build an E-Commerce ASP.NET AJAX Application", we decided to pick up from where he left the example and extend it to a fully working application incorporating RadControls and the EBay's OData feed.

We loved the idea of a MetroUI based layout and introduced the new Metro Skin for RadControls, which fit the initial design with almost no customizations.

This was also a great opportunity to demonstrate the new OData Client-Side binding feature of RadGrid. So we rolled up our sleeves and set to work.

After playing around with the...

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...

The third, and final, episode of the ASP.NET AJAX webinar series took place yesterday. Much like with the first to webinars I wanted to make sure that I followed the webinar with a blog post containing all of the questions asked during the presentation, as well as a link to all of the recorded webinars. You can find a list of the questions asked below, and as always if your exact question is not found here then it’s due to a duplicate (or very similar) question.

Q&A

• Can the RadAjaxManager support partial post back that appends new controls to the page?
  ...

Part two of the webinar series occurred yesterday and, just like with the first one, I wanted to follow up with a blog post answering all of the questions that came up. I also wanted to thank everyone that attended, you guys were great and were very attentive (as I saw after reading the chat logs regarding my initial Eval statement!). Your exact question might not be included here, but that’s just due to a duplicate (or very similar) question. You can find all the answers to the questions below:

• Will this code be made available for download the webinar? ...

The Open Data Protocol – the other Microsoft data access strategy along with WCF RIA Services, did not gain as much as popularity as its RIA cousin (yet!). But here in Telerik we want to give you as much freedom and power as possible and this means making it extremely easy for our clients to access and manipulate their data in applications built with our components. Our RadDomainDataSource is coming soon, but is only one piece in the puzzle of enhanced data support in our controls – starting with RadControls for Silverlight and RadControls for WPF Q3 2010 it’s as simple as pie...

RadGrid's client-side databinding capabilities got boosted to a new level with the Q3 2010 release of Telerik RadControls for ASP.NET AJAX. RadGrid now supports automatic databinding to OData web services. For those of you who have never heard, OData (short for Open Data) is a data exchange protocol that enables data transactions to be carried over standard web protocols (HTTP, Atom, and JSON). OData exposes your data over the web to a variety of consumers, building on technology that is widely adopted.

With the Q3 2010 release, we have added automatic client-side databinding support for OData services. To configure RadGrid for binding to an OData service, you...

Similar to this post, I’ve made a similar example on how to load on demand RadTreeView for Silverlight three level hierarchy using MVVM and OData service:
