Telerik UI for Winforms

Release History

Q1 2014 (version 2014.1.226)

February 25, 2014

RadBindingNavigator (New Control)

RadBindingNavigator provides a basic UI for navigation through a collection of business objects. Its UI also allows you to add and delete objects. You can use RadBindingNavigator to browse the data of controls bound to a BindingSource. It works flawlessly with one of the other new controls we are introducing in Q1 2014—RadDataEntry

RadCollapsiblePanel (New Control)

RadCollapsiblePanel is a flexible control that helps you save space and achieve easier navigation through your application. You can embed any content inside its collapsible area and set the ExpandDirection to adjust the control's layout per your custom requirements. It also provides built-in expand/collapse animations that you can turn on or off by setting the EnableAnimation property.

RadDataEntry (New Control)

RadDataEntry provides an easy way to display and edit arbitrary business objects in a form layout. The built-in editors are generated by default, so you can achieve a fully operational CRUD support with a single line of code by simply binding to the business object, or to a collection of objects. RadDataEntry provides a built-in validation mechanism you can easily customize according to your validation criteria.
