I'm currently using the RadChart (Q1 2011) in a complex scenario where in a MVVM approach I am binding the chart series to the View-Model to create a truly dynamic chart. I am also using a "Telerik approach" custom theme for my application.
Disappointingly, I cannot upgrade my application to Q3 2011 because this release grudgingly refuses to work for my solution. A series of styling issues and cryptic exceptions has stopped me from proceeding any further. You may view the related posts here
. Frustrated with the breaking changes (why are there breaking changes to begin with?!?), I spent many futile hours trying to migrate my RadChart to the new RadChartView but quickly found that the RadChartView is not ready for real world problems (chart Series are not bindable).
My question is will you be fixing up RadChart so that it will work for Q1 2012 OTB (out-of-the-box) when I upgrade?

This is a reminder to Telerik that if you intend to release new versions, please do the following:
1. Clearly identify the breaking changes.
2. Update your documentations, clearly marking the changes required to get a working solution.
3. Provide an alternative if all-else fails.
I would also like this post to serve as a warning to other developers thinking about upgrading to a newer version. Find out what works and what will break before you waste your value development time trying to guess the errors and end up reverting to an older working version.
