Cannot enable the text item after disable it in Forms 6i

Question

Hi All,
I want to enable/disable the text items depending on the value of the radio group. Since the text items and the radio group are on different tab page, so I place the following code on the WHEN-TAB-PAGE-CHANGED trigger, to do this:
if :recordgroup ='P' then
set_item_property(item1, ENABLED,PROPERTY_TRUE);
set_item_property(item1, NAVIGABLE,PROPERTY_TRUE);
elsif :recordgroup ='K' then
set_item_property(item1, ENABLED,PROPERTY_FALSE);
set_item_property(item1, NAVIGABLE,PROPERTY_FALSE);
end if;
When recordgroup is 'K', item1 is disabled, then when recordgroup has changed to 'P', item1 is still disabled.
Both recordgroup and items are database items.
How come like this?
Thanks is advance,
Vanessa

Hi Vanessa, you must use a "when-radio-changed" trigger, and you need to know what properties of a item are afected when you change any one of this, for your problem ...
if :recordgroup ='P' then
set_item_property(item1, ENABLED,PROPERTY_TRUE);
set_item_property(item1, NAVIGABLE,PROPERTY_TRUE);
-- Add this line:
Set_Item_property(item1, Update_Allowed, Property_True);
elsif :recordgroup ='K' then
set_item_property(item1, ENABLED,PROPERTY_FALSE);
-- If you want, you can delete this line:
set_item_property(item1, NAVIGABLE,PROPERTY_FALSE);
end if;
try it!
Ruben.
