Although we are trying to keep the number of breaking changes at the minimum, some features just can't be implemented without redesigning certain parts of RadControls. We are listing the introduced breaking changes in our Release Notes
. You will notice that they are marked in red for better readability. The most important list of changes is the one concerning Q2 2010
. It this version included a completely redesigned RadGridView control, along with one new control (RadPageView) that substitutes RadTabStrip and RadPanelBar. Moreover, RadListBox and RadComboBox are replaced by RadListControl and RadDropDownList respectively. RadPanelBar, RadTabStrip, RadComboBox and RadListBox are still a part of our code base, but they are obsolete and will be removed in a future release. You can take a look at this article
which describes how you can update the obsolete controls to the new ones.
