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:

With this blog post I want to cover the very basics of our brand new RadScheduleView control. It is currently available only for WPF, but soon we will provide a Silverlight version. Please, check my FAQ about RadScheduleView blog post for more information:

http://blogs.telerik.com/valerihristov/posts/10-10-25/telerik_scheduleview_for_silverlight_wpf_questions_and_answers.aspx

To add RadScheduleView to a new or existing application you need to first add references to the following assemblies

Telerik.Windows.Controls

Telerik.Windows.Data

Telerik.Windows.Controls.Input

Telerik.Windows.Controls.Navigation

Telerik.Windows.Controls.ScheduleView

If you like to drag controls from the Visual Studio Toolbox, add RadScheduleView to the Toolbox following the instructions below (in the official release it will be automatically added when you install RadControls):

I am a fan of the manual...

I would like to answer a few questions that you might have about our brand new RadScheduleView control.

Q) When is the Silverlight version coming?



A) We will do our best to provide the Silverlight version by the end of the year.

UPDATE: We already published a pre-beta version that can be downloaded in this forum. The Beta is expected in Mid February, the RTM version will be available with Q1 2011 in Mid March.

Q) Why did you create a new control instead of changing the existing RadScheduler?



A) We wanted to address...

The Q3 release RadControls will come packed with shiny features and a couple of new controls, but that’s not all! We’ve fiddled with the complex machinery under the hood and made it better too.

Let me introduce you the new and improved provider interface (ABC, actually) for RadScheduler:

Due to the rising popularity of Rich Internet Applications (RIA) e.g. Silverlight applications, the developers get more dependent on services for coordinating application logic between the middle tier and the presentation tier and the logical question raises how to use an already working WCF RIA Service as a datasource for Telerik Report. This is very useful if you want to enable the exact same business data access logic for clients other than Silverlight. For example to a WPF, WinForms or WebForms application. Thus we have made some tests locally and decided to share our observations in this post.

Prerequisites:

We will examine the WCF...

Q3 2010 is around the corner and it will be yet another promising release for RadControls for WinForms. In the previous milestone we introduced 5 new controls, added a faster and more robust data layer to RadGridView and improved its UI layer.

Our last major release of the year will deliver an enterprise upgrade to the Telerik GridView and Scheduler controls which will enhance demanding LOB applications with better user experience and performance.

We already started the pre-release blog wave with WPF and it is time to continue with some details about the Telerik suites for ASP.NET AJAX and MVC.

The highlight of the upcoming Q3 2010 release for RadControls for ASP.NET AJAX is the addition of two new controls – RadTreeList and RadButton.

RadTreeList is a valuable extension of the toolset as it adds yet another means to display data in hierarchical format. The treelist combines the flexibilities of a traditional treeview and a grid in one hybrid control. It will give developers the freedom to manipulate the underlying data and display it in...

Several weeks before the official release we wanted to give a preview of some of the major new controls and features coming in Q3 2010.

The new ScheduleView control for WPF 

As we announced in the beginning of this quarter we started working on a brand new scheduling component. Now that the first bits appeared you can find the new ScheduleView in the RadControls for WPF bundle. We decided to develop this new control as we wanted to prepare a really advanced Scheduling control that would fit in any application scenario. You can review the major features of the control on its product...

I’m happy to announce that with our Q3 2010 Release of RadControls for Silverlight and WPF you will be able to load records on demand using our brand new VirtualQueryableCollectionView:

The collection will load records only when needed and you can check it in action on our beta demos:

I’ve attached also two applications to illustrate how to use VirtualQueryableCollectionView in different scenarios:

- Using ItemsLoading event / Load() method in Silverlight Download
