how to set item property of a text item in oracle form ? please advise
my name is Kim Dinh . thank you all for reading this post ...I have problem in setting (or change) item property of a text item in my oracle form (still under 32 bit -Oracle Form 6i- running from web portal) ..the story is : after extracting Serial Number from the table , if Serial Numberexist , I will populate the text item field( 20 char ) with it , otherwise the field will be Null .. I want to prevent user from updating this field if Serial Number exist when canvas display this field ...I tried to use SET_ITEM_PROPERTY(pw_block.SN, UPDATEABLE, PROPERTY_FALSE)
