    (Re)Mixed Hierarchy Mode in RadGridView for WinForms

    In addition to the fact that our next release focuses mostly on our accessibility and automated testing as described in this blog post, in our upcoming version we will include many bug fixes in all RadControls for WinForms, including a highly optimized version of RadTreeView. In this article however, we want to present a new interesting feature in RadGridView that you will surely find useful. A customer of ours requested a mixed hierarchy mode where he wanted to use a self-reference hierarchy AND the classic hierarchy mode together. The scenario that he described used a file explorer where the main level...

    OData support in RadGridView for Silverlight and WPF: The Netflix Catalog

    December 11, 2010 Share
    The Open Data Protocol – the other Microsoft data access strategy along with WCF RIA Services, did not gain as much as popularity as its RIA cousin (yet!). But here in Telerik we want to give you as much freedom and power as possible and this means making it extremely easy for our clients to access and manipulate their data in applications built with our components. Our RadDomainDataSource is coming soon, but is only one piece in the puzzle of enhanced data support in our controls – starting with RadControls for Silverlight and RadControls for WPF Q3 2010 it’s as simple as pie...

    Using GridView's Object-Relational Hierarchy with Telerik Open Access ORM

    November 30, 2010 Share
    In our previous blog post we showed how to use the new RadGridView Object-Relational Hierarchy with the Entity Framework. The same scenario can be easily implemented with Telerik OpenAccess ORM. The OpenAccess wizard for adding a new DomainModel will help us build the model of the well-known Northwind database in a few easy steps: Once this is done, the auto-generation of the hierarchy is very simple and needs just a few lines of code. We only need the LINQ query to the root object used for a DataSource (in our case “Suppliers”) and then setting AutoGenerateHierarchy to true: NorthwindEntities entities = new NorthwindEntities(); var query =...

    Expression Descriptors in Q3 2010 for WPF & Silverlight

    November 11, 2010 Share
    Another four months have gone by and another awesome release of RadControls has arrived! One of the exciting new features in this release are the so-called 'Expression Descriptors'. Previously, whenever our clients wanted to filter data but needed even more control than our good old FilterDescriptor could provide, they had to subclass it and override some of its methods. Even though that approach works, it is tedious and cumbersome. And, as much as LINQ Expressions rock, having to manually generate expression trees by hand... yuck! The new FilterDescriptor<T> allows you to directly plug a predicate that determines which items are filtered. You...

    Bringing User Experience to the next level in RadGridView for WinForms

    In the upcoming Q3 2010, we bring the extensibility of RadGridView to the next level. We will add the ability to create and replace the row type for all rows stored in the rows collection which will give our customers almost unlimited control over the customization and design of the control. The new feature gives developers the opportunity to extend the default behavior of all descends of the GridViewRowInfo class. Here is how it works: Let’s say that you want to create an expandable filter row which has extended user-friendly UI for filtering: In Q3 2010 this will be possible with a few simple...
