Spatial data is all the rage, everyone wants a map in their application to quickly visualize data.  In a previous blog I showed how you could query, and display, SQL Spatial data on RadMap for WPF using Telerik OpenAccess ORM.  In this blog, I will show you how to display the data on RadMap for Silverlight.  This adds a slight twist because we need to transport the SQL Spatial data across a service boundary, but thanks to some updates in RadMap this is still an easy process; so lets take a look! Database Setup The first thing we need is some spatial data. In...

SharePoint provides types and members in the Microsoft.SharePoint.Client namespace for accessing SharePoint remotely from a client computer or server. To get started with SharePoint client object model you will need Microsoft.SharePoint.Client and Microsoft.SharePoint.Client.Runtime assemblies. You can copy these DLLs from the %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\ISAPI folder of the server that runs Microsoft SharePoint Foundation 2010. Using the Microsoft.SharePoint.Client types you can get access to SharePoint List data. However in order to have design time support (Telerik Reporting Data Explorer, Wizards and Expression editor) with SharePoint as data source, you will need the following SharePointDataSource helper class. This class manages the SharePoint credentials,...

One of the new features of the chart control for the Q2 Beta2 release is an API for behaviors. We decided do decouple the chart from some of its features and make them separate objects for the usual software development reasons. Now RadChart has a Behaviors collection that accepts ChartBehavior objects. Whenever an object is added to or removed from this collection a feature is either enabled or disabled in a RadChart instance respectively. We provide three behaviors out of the box and these are ChartPanAndZoomBehavior, ChartTrackballBehavior and ChartToolTipBehavior. The tooltip behavior allows the chart to show a tooltip wherever the user taps...

I like agile user stories. They make sense to me. 15 years ago – I wrote a lot of “Use Cases”. As use cases seemed to have some components I liked – they frightened and intimidated me - I found that as use cases would gradually become more complicated and cumbersome to write – I spent all my time writing, debugging, and maintaining them – yet, I found I was still not communicating with my customer or my development team very well. Quality didn’t improve. We still were at risk of building the wrong product. Agile User ...

Recently there was a feature request for out-of-the-box support for a ToolTip while dragging any of RadSlider's thumbs. Since we don't provide one yet we decided to check whether it is possible to accomplish this scenario with the current implementation of RadSlider. It turned out that it was actually quite trivial. Few attached properties, a little bit of knowledge about tooltips in Silverlight and voila! Below is the class that does all the magic. It is pretty self explanatory. public class SliderToolTipExtensions : DependencyObject {     private static string SingleThumbName = "SingleThumbHost";     private static string RangeStartThumb = "RangeStartThumb";     private static string RangeEndThumb = "RangeEndThumb";       private static string ValuePropertyPath = "Value";     private static string SelectionStartPropertyPath =...
