About RadTreeView for WinForms and its Supercharged engine
In Q1 2011 we introduced a highly improved version of the RadTreeView control which had all of its internal parts rebuilt in order to support full UI virtualization and customization. This allowed us to attach a new data engine that provided many new and useful features such as built-in filtering and sorting independent from the external data-sources, and support for CRUD operations. For Q3 2011 and Q3 2011 SP1 we made additional improvements to our data engine and in the synchronization between the UI and the data layers. Now, there are two questions which we have been asked lately: “Is the new RadTreeView...

RadTreeView for WinForms Q1 2011 with a new engine under the hood
We were eagerly awaiting the Q1 release to demonstrate you the new cleaner and more flexible API that makes the work with RadTreeView fun. We also wanted to tell you something more about the benefits that come with the new data engine.

Controlling TreeView’s ExpanderStyle Dynamically
Sometimes the TreeView is used in scenarios where the expander style must be styled in custom fashion. Prior 2010 Q3 SP1 there was no easy way to dynamically change the expander style of the TreeView or particular item. TreeView’s ExpanderStyle So we decided to extend the functionality provided by the TreeView. Prior this enhancement changes to the ExpanderStyle property during runtime would not affect already visible items. The property now supports dynamic values and data binding. This way you can easily change the style of the expander of all items in the hierarchy during runtime. Item’s ExpanderStyle Working only with the TreeView’s ExpanderStyle...

Quite often TreeView is used in scenarios where a particular item should be displayed on the screen. You may want to display some item when the tree is initially shown on the screen or when a new item is added. These scenarios look simple but are a bit tricky because you have to wait until the TreeView loads and then make your desired actions. Waiting for Loaded Event TreeView provides the BringIntoView functionality in several forms: you can call BringIntoView from the tree itself and bring a child item; get some TreeViewItem by calling GetItemByPath and call BringIntoView upon this item container;...
