[Lazarus] dbgrid with a lookup field
please see https://docs.google.com/document/d/1RprJLM1i7dgJvfz-lDryH-Jc9I8xVv8gvzsKeYoI6Ps/edit?usp=sharing I have a DBGrid with a lookup colum, say column 0. The user selects a row in the picklist and the focus goes to the undelying lookup cell (0), what makes sense. However I'd like the focus set to cell with index 2 in the row. How do I do that? Which event is fired when the user makes a selection in a lookup column? Thank you Peppe Polpo -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Issue #40774, patch by Bernd Jung. Anything else I could check ? Please bisect to find commit that broke it for you. I did that, going back half a a year (I did my last lazarus update roughly 2 months ago). It didn't change anything. So I rebuilt 'bigide' instead of 'useride'. All worked. I then removed the anchordockingdesign package, and after a make of useride, the bug was no longer there. Meaning the error is in the anchordocking package. It seems I didn't start a new project since I activated anchordocking. (which is a little over a month ago...)
