Previewformcreate Event

rbuser

?Not sure if I have this correct. created the event but on preview of
report the event is not fired.
Does this only work with custom preview forms?

What I was hoping to do was set the preview forms caption, or is there
another way of doing it?

In my quick testing, the OnPrevewFormCreate event is firing correctly
and as designed.

Are you loading templates? If so, you need to be sure to assign this
event after the template is loaded.

Yes I am loading templates.

Why assign it after a template loaded would make a difference?

But will try it after the template is loaded.

Thanks

Report templates save the entire report definition including event
references. By loading a template you are essentially clearing out all
existing event references to the report object and replacing them with
the references saved with the template. Once the template is loaded,
you need to re-assign any Delphi event handlers to avoid loosing them.

A more elegant solution would be to keep all event code local to the
template using RAP.
