Regarding the RadHtmlChart-DrillDown-RadDock.zip demo I have tried to reproduce the described behavior but to no avail. You can watch a short video with the test here
, and then tell what I am missing.
I have used the Telerik.mdf database and the corresponding fields like in the HtmlChart - Drill-down Chart
online demo. It might be possible that you are referencing invalid fields from this or other database. However, without having enough information about your actual scenario it is difficult to reproduce the unexpected behavior. What I can suggest you is to open a support ticket and send us a fully runnable sample with reproduction steps of the issue
, so we can proceed further with the investigation.
Regarding the second example - RadHtmlChart-DrillDown-RadDock-UpdatePanel.zip, you are right that the drill down clicking performs a full postback and not partial one, so please accept my apologies for the caused mistake. The reason for the unexpected behavior is because the hidden button that is being clicking is put outside of the update panel's boundaries. What I have done in order to fix that was to move the button itself together with its server-side event inside the area of the update panel. Please find the reworked example in the attached archive.
