Reporting: Using connectionStrings from configuration file
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! ---------------- Steve... -

LINQ Tip of the week: System.String support
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 ...August 28, 2009 1 min read -

TreeView in ComboBox, take 3 (Silverlight 3, WPF and RadControls)
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...August 28, 2009 3 min read -

WebAii Testing Framework: From HTML to XAML and Back -- RadHtmlPlaceholder
Along with the Service Pack of RadControls for Silverlight Q2 we released an update of the free test automation solution, the WebAii Testing Framework. There are additions, fixes and improvements in all the components including the core WebAii, WebAii RadControls for Silverlight and ASP.NET AJAX. With this post I’d like to bring your attention to the latest addition to our Silverlight controls wrappers – the RadHtmlPlaceholder one. As you probably know, the control itself is a pretty useful component part of the RadControls for Silverlight suite.August 27, 2009 3 min read -

Multi-Item Drag and Drop with the RadListBox for WinForms
Earlier this week, I ran across a forum post asking about how one would go about creating multiple RadListBoxes that supported multi-item drag and drop. This sounded like a fun challenge, so I decided to take it on. Referencing an earlier forum post that described single-item drag and drop, I came up with the following solution. Calling DoDragDrop() immediately changes the mouse pointer and readies the RadListBox for the drag-and-drop operation. Originally, I had tried calling this function in the MouseDown event, but this lead to unpredictable clunky behavior due to the fact that DoDragDrop() was getting called before I had the chance to ...August 27, 2009 1 min read -

Self-reference hierarchy with Telerik TreeView for Silverlight
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 {...August 27, 2009 4 min read -

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...
