I must admit that coming up with a meaningful and relatively short title was really hard this time. Anyway, here is the scenario:
The problem is related to the fact that every splitter movement (no matter how small it is) triggers update of the whole layout cycle (measure-and-arrange) for the grid contents, and the framework cannot cope with that for a control with complex layout mechanics like RadChart. The solution? You can take advantage of the RadChart Exporting API and improve the user experience of the application by replacing the actual chart control with a snapshot image during the splitter drag action (once the drag is complete, you can restore the actual control).
Here are the necessary steps in order to achieve this functionality:
You can find attached a sample application as well.
Hope this helps.
