I have a form with TCaptionPanel's when I try to set the caption after using FindComponent I get an error:

Unable to get property 'tcaptionpanel_setcaption of undefined or null reference

TCaptionPanel(FindComponent('Item' + IntToStr(i))).Caption := MyText;


The TCaptionPanel do have property called Caption;

I tried other properties and I get an error on all of them.

Thanks,
Kim

The FindComponent is returning null, so the component might not exist. I think the name of components is not necessarily set - a while since I dug into that. You'd be better off keeping an array of objects and keep references to the components IMO.

Try to specify the container control, e.g.:

TCaptionPanel(<CaptionPanelParentControl>.FindComponent('Item' + IntToStr(i))).Caption := MyText;

Thanks Uli, that did it.
