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...

Having the ability to quickly, and easily, present an important piece of information to your users is very important. However, having a huge window or a JavaScript alert popup appear in the middle of the screen certainly isn’t too discrete and can end up annoying the user. This is why we created the RadNotification control. This new component allows you to have a similar popup to what you might already be used to from Outlook, a quick box that appears somewhere on the screens and then later disappears. In this blog post we will take a look at this new...

Have you ever searched for a quick and simple way to notify your users that something new is going on? Or just to show them some status message upon specific condition or time interval? This is now pretty easy to achieve with the new RadNotification control which joins RadControls for ASP NET AJAX suite in the Q2 2011 release!

Until now, you could achieve the same effect by using some popup in multiple approaches but you will always need to add a timer, load on demand code, server script or something else, depending on the exact requirements and that is why...

This blog post will show you, how to use the new lower level ADO API to execute stored procedures that are returning out parameters, return values and multiple result sets. In this example we will use Microsoft SQL Server 2008 as backend which supports combining all of these features.

The Setup

We create a new Console Application project. Next we add a reverse engineered Domain Model based on the Northwind database.

Let’s add a stored procedures to the database which will cover all our requested features.

   1: CREATE PROCEDURE SPCombinedFeatures @InParameter INTEGER, @OutParameter INTEGER OUTPUT

   2: AS 

   3: SET @OutParameter = ( SELECT COUNT(*) FROM [Categories])

For those of you that attended the What’s New for Desktop Developers in Q2 2011 Release Webinar, thank you for attending!  For those that didn’t get to attend (or for those of you that want to go back through it since it was jam packed with information), the recording worked perfectly, and I will be posting it to Telerik TV in the next 48 hours! 

Several people attending the webinar asked for the source code for my project that I created to demo the features as well as the powerpoint slides, and you can get them both here (slide deck, code...
