    RadControls version 2012.1.326
    Silverlight version 5.0
    Visual Studio version 2010
    programming language C#
    browser support

    all browsers supported by RadControls

    This project demonstrates how to implement a 'tri-state' CheckBox logic in the RadTreeView while using an MVVM approach. As the built-in RadTreeView 'tri-state' support is designed to work in a declaratively defined RadTreeView, in an MVVM approach you need to create custom logic. You can add a CheckBox control in the ItemTemplate of the RadTreeView and implement the 'tri-state' logic in the view models.
