If you've been along for the ride so far with this series, you already know that we've hooked a SQL database up to RIA Services using an ADO.Net Entity Data Model and a DomainDataService data context. If you've missed it, check out the prior two posts (or search RadScheduler for Silverlight learning series in the Telerik Blogs site). Now that we're here, we have three more events to handle and we've got a fully-functional RadScheduler for Silverlight hooked up to RIA services. First up, the two easy events- AppointmentAdded and AppointmentDeleted. AppointmentAdded Event This event is pretty straightforward and does not require very...
If you think the light from the Silverlight 3 release has already gone dim, then you should wait to see the new blast that the Telerik team has prepared just to make sure that once again everybody is looking in the same direction. In this article I will introduce one of the new controls that are already extending the enormous capabilities of Silverlight 3.
One of the buzz words that came up with Silverlight 3 is the Plane Projection that allows you to render UI element in a plane projection. We have been passionately waiting for this and...
In a recent webinar, I showed an example of how you can build a superior user experience in an ASP.NET website by using RadChart for Silverlight. The Telerik Silverlight chart has animations, rich rendering, and is much more visual appealing than the “static” RadChart for ASP.NET. But while the Silverlight chart is a great way to enhance data visualizations in your ASP.NET site, how do you handle users that don’t have Silverlight installed? One approach is to implement “graceful degradation.” Graceful degradation is an important and familiar principle in web design, and essentially it means this: if you build features into...
If you are using some of the predefined modal dialogs part of RadWindow: Alert, Prompt and Confirm you may find this article quite handy. As you know the calls to these methods are asynchronous, thus you cannot stop the current UI thread in order to get the user feedback from the windows synchronously. This introduces some issues such as the need to declare class member variables whenever they may not be necessary. Due to that there have been a few requests on our support website to create a generic parameter inside the static calls of the dialogs with the purpose of carrying...
It’s often necessary to modify or format some of the raw data received by your data tier application or other data sources. In Silverlight, you can create your own value converter and introduce your own formatting rules. In this blog post I will create a simple value converter that formats double values, and then use it with a RadComboBox. First, let’s create a class that will represent our data source. The equivalent of this class in more realistic scenario would be a proxy class generated by your data tier application in case you use RIA services. public class Data : List<Item> { public Data() { this.Add(new Item() { Name = "Ferrari", Price = 120000 }); this.Add(new Item() { Name = "Mercedes", Price = 100000 });...
