Title: datamodule
Post by: Medhome on August 07, 2022, 04:23:32 pm

Hi all,

     I wrote a procedure  sumField in form1 and I want to replace the last procedure corresponding to afterOpen event in datamodule of my application.

Can I connect the AfterOpen event on the DataModule from Form1? .

Regards
Med

Nb:
I did datamod.dataset.afteropen := sumfield  in form1   No success.

Data module is just another UNIT, include the unit name in the list of units in your USES list of where you need to access it from.

The AfterOpen event  is fired in the datamodule not in form1!

try: datamod.dataset.afteropen := @form1.sumfield

HI bpranoto,

   That works.

     @sumfield   works also cause we are in form1 .

Thank you.
