Thank you for writing.
The observed error is expected, since in Q3 2011 we have removed all our obsolete code from our code base. Release notes can be found here: http://www.telerik.com/products/winforms/whats-new/release-history/q3-2011-version-2011-3-11-1116.aspx
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.
If you were using some of the other obsolete controls, information about their upgrade can be found at the following links:
- RadTabStrip to RadPageView
- RadPanelBar to RadPageView
- RadComboBox to RadDropDownList
- RadListBox to RadListControl
I hope this helps.
