Thank you for contacting Telerik Support.
In Q3 2011, we have removed all obsolete controls from our code base after they were marked as obsolete for more than one year. The release notes are available here:
My advice for this case will be to perform the upgrade in two stages. First, upgrade to Q3 2010 where all obsolete controls and their descendants exist. For most of the obsolete controls, we offer a Conversion Tool, which will help you with the conversion. This tool can be used for the following conversions:
- RadTabStrip to RadPageView
- RadPanelBar to RadPageView
- RadComboBox to RadDropDownList
- RadListBox to RadListControl
Additionally, If you have used the old implementation of our docking control (DockingManger), you will be able to convert it to the new implementation ( RadDock ) again from the option in the old control Smart Tag.
The only obsolete control which you will manually convert is the RadToolStrip control. The reason for not providing a tool for conversion of this control is the fact that both controls are semantically different, so you will have to manually recreate the control by using RadCommandBar . From my experience, I can say that this is an easy conversion.
After you convert all your controls to their descendants and clean all errors and warnings, then you can perform an upgrade to the latest version.
I hope that you find this information helpful. If you have any questions, during the transition process, do not hesitate to contact us.
