Prism can be thought of as a set of libraries that help Silverlight applications to be scalable and testable. It has a number of features (modularity, view regions and commanding) that help with this. A common scenario is to use Prism with a Docking control. You may want to create a shell with a Docking control and to mark some of the pane groups as regions and to use panes (or their content) as views.

In this article we will create a sample application that accomplishes this scenario with the RadDocking control for Silverlight. We will need one additional step to...

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...

We've been asked several times, what is the right way of using connection strings from the configuration file, so that Telerik Reports would work both in run time and design time. The answer can be found in this new Knowledge Base article:

Using connectionStrings from configuration file

It is worth mentioning that the Report and Data Source Wizards do this automatically when instructed to save the selected connection string in the config file.
A working solution using the approach from the latter article can be found in our Visual Studio examples.

Enjoy!

Welcome back for some more information about the Telerik OpenAccess ORM support for LINQ.

Today we provide a brief list of the System.String properties and methods that are supported by our LINQ implementation. When any of the below listed methods are used in a LINQ query, Telerik OpenAccess ORM translates the method call to equivalent SQL which is then executed on the server.

Please note that the table lists the MS SqlServer specific SQL translation.

 

Properties

String.Length

len (string_expression)

 

Methods

String.CompareTo	expression = expression
String.Contains	match_expression LIKE pattern
String.EndsWith	match_expression LIKE pattern
String.Equals	expression = expression
String.IndexOf(String)	CHARINDEX (expression1,expression2, –1)
String.IndexOf(String,Int32)	CHARINDEX (expression1,expression2, start_location)
String.Insert	CASE   WHEN( LEN(ISNULL(column_name,'')) = start_index) THEN ISNULL(column_name,'') + value ...

In my previous article on the same topic I described how to replace the ItemsPresenter of RadComboBox with a RadTreeView. It was as simple as updating the control template. Unfortunately the controls’ selection synchronization relied on a bug in RadComboBox that we recently fixed – the control was able to have a value in its SelectedItem property, that was not present in its Items collection. Now, in order to workaround this new problem, we have to either inherit RadComboBox, or create an attached behavior that will allow us to get the SelectedItem of the inner RadTreeView. The code you have to write...

To enable support for Visual Studio 2010 Beta 1 you will need to select “Complete” when installing RadControls for ASP.NET AJAX Q2 2009 SP1

 

 

One cool new feature of Visual Studio 2010 is that snippets now work in the HTML editor. Code snippets for C# and VB have been supported in previous versions of Visual Studio, however the new HTML Snippets feature gives you the same productivity boost when writing markup or ASP.NET server control declarations in the HTML Editor.

 

The following procedure describe how to use RadControls for ASP.NET AJAX code snippets:

 

• In Visual Studio 2010, on the File menu, point to New...

Often we need to display in a TreeView flat, self-referencing data, loaded from a database, that has properties ID and ParentID (or similar) that define the hierarchy. The Telerik TreeView for ASP.NET can automatically bind itself to such data, but our Silverlight TreeView cannot do this out of the box. Fortunately, this “limitation” can be easily avoided with a simple value converter. There is a little trick, however – each data item needs a reference to its parent collection.

Consider the following very simple data object:

public class DataItem : INotifyPropertyChanged
{
    private string text; 

 public int ID { get; set; }
    public int ParentID {...

The following video shows how to use the Telerik OpenAccess WCF Wizard with ADO.NET Data Services. The video is done by .NET Ninja in training Peter Bahaa and uses more or less the same code I showed yesterday on my blog. Enjoy!

 

Telerik OpenAccess WCF Wizard Part II- Astoria from Stephen Forte on Vimeo.

I have been a big fan of using the RESTful ADO.NET Data Services (aka Astoria). If you want to use Astoria out of the box without any modifications you really have to use the Entity Framework. But as long as you are using a data access library that supports IEnumerable and IQueryable (and IUpdateable to be useful for CRUD) you can use Astoria with just a little bit of extra work. 

Telerik OpenAccess supports LINQ and IUpdateable and can be used in Astoria as shown here. In a nutshell you have to first create your data access layer, then a web site to host your ADO .NET Data Service and...
