Hello,
I currently have problem in a project. The whole page is within Telerik's controls RadSplitter and RadPane. When we use jqChart outside of them everything works fine. After loading the page Chart is visible but if it is inside Telerik's controls and we do a PartialPostBack whole chart disappears.
I read in your forum that around a year ago you had problems with update panel, is it the same situation here or did you fixed update panel problem and this is a new issue.
Best,
Bartłomiej Bocian
