Re: Popup list callback function not being called...urgent help needed

[Vidya Amar]

Rodolphe,
            Yes, I tried the following to set the no. of items in the list.
Still the callback function  is not being called when the form opens.
        LstSetListChoices(List, NULL, n);//n is set from the no. of records in the
database
        LstSetDrawFunction(List, MainListDraw);
The callback function however gets called when the popup trigger is selected
after the form opens. Can you please help me to get the callback function
working on the form open?
Vidya.
did you set the number of items of the list before, so the callback is
called as many time as the number of item specified ?
