APEX

i have a page with following components.

a report that has and edit link.
a text box to catch the primary key from report link when it is clicked
a number of elements (text boxes, check boxes and LOVs) which are used as data entry form.

Now my design is that user enter values save them and no sooner did they save, the report depicts new
values. if user want to edit any record, they click on edit link and the data entry form elements
should now bring all those values from DB on page. i m successful to pick primary key and bring
it in a hidden text box and wrote a dynamic action on its change event that will bring values from
DB and set all page elements. but but but.........the change event doesnt work. it only work
when focus is lost from the text box...!! offcourse user wont want to click in that "hiddent" text
box and then click some where else to bring values in page data entry form......

help is humbly requested from forum or if any other solution approach is to be used easier than
one i m using, would be appreciated.

thanks in advance for reading my bore question :)
