Question

Dear Friends,
I'm new to the oracle forms .. i want to restrict a filed update against a condition in my form.
I am using multi record block. I want to disable few fields in a row e.g. there are 10 records in the record block i want to disable three items of 2nd record on the basis of some condition. How can i do it??

HI,
you can use the form-built in procedure SET_ITEM_INSTANCE_PROPERTY and the appropriate property....(UPDATE_ALLOWED = PROPERTY_FALSE).
For example:
  begin
    if <your_condition>
      then
          set_item_instance_property('<your_item1>',<record_number/CURRENT_RECORD>,UPDATE_ALLOWED ,PROPERTY_FALSE);
         set_item_instance_property('<your_item2>',<record_number/CURRENT_RECORD>,UPDATE_ALLOWED ,PROPERTY_FALSE);
     else
         set_item_instance_property('<your_item1>',<record_number/CURRENT_RECORD>,UPDATE_ALLOWED ,PROPERTY_TRUE);
         set_item_instance_property('<your_item2>',<record_number/CURRENT_RECORD>,UPDATE_ALLOWED ,PROPERTY_TRUE);
    end if;
  end;
