Hi All,

I'm new member! Thanks for atention and sorry for my english.

I need know how do for disable or enable only a item (text item field type) based in other checkbox field type and not all my block.

For example bellow:

--Enable/Disable TEXT_ITEM1
IF   (NVL(:UNINEG_TIPO_DESPESAS.CHECK_BOX_ITEM, 'N') = 'N') THEN
     SET_ITEM_INSTANCE_PROPERTY ('TEXT_ITEM', CURRENT_RECORD, UPDATE_ALLOWED, PROPERTY_FALSE);
     SET_ITEM_PROPERTY          ('TEXT_ITEM', BACKGROUND_COLOR, 'r214g214b214');
ELSE
     SET_ITEM_PROPERTY          ('TEXT_ITEM', BACKGROUND_COLOR, 'r255g255b255');
     SET_ITEM_INSTANCE_PROPERTY ('TEXT_ITEM', CURRENT_RECORD, UPDATE_ALLOWED, PROPERTY_TRUE);
END IF;



I did inserted the code up, in post-query and pre-record triggers from my block and when-checkbox-changed in trigger from checkbox item, but, no functioned. The system saw the selected line only and enable/disable all my block instead of disable only the line selected.

Anybody can help me, please?

Thanks guys!

The above code sets the update allowed for a single instance of an item in a block and the background colour of all the instances of the item in the block. You can set visual_attribute using set_item_instance_property.

Show us your code... My first impression is that you are not passing the CURRENT_RECORD parameter to the Set_Item_Instance_Property() built-in, but we need to see your code to confirm what the cause is.

Hi Craig,

Thanks for help!

Bellow my code, I'm inserted in post-query and pre-record triggers from my block and when-checkbox-changed, when-validate-item and post-change trigger in my check-box item.

Quote:

--Enable/Disable TEXT_ITEM
IF (NVL(:MY_BLOCK.CHECK_BOX_ITEM, 'N') = 'S') THEN
SET_ITEM_INSTANCE_PROPERTY ('TEXT_ITEM', CURRENT_RECORD, UPDATE_ALLOWED, PROPERTY_FALSE);
SET_ITEM_INSTANCE_PROPERTY ('TEXT_ITEM', CURRENT_RECORD, NAVIGABLE, PROPERTY_FALSE);
SET_ITEM_PROPERTY ('TEXT_ITEM', BACKGROUND_COLOR, 'r214g214b214');
ELSE
SET_ITEM_PROPERTY ('TEXT_ITEM', BACKGROUND_COLOR, 'r255g255b255');
SET_ITEM_INSTANCE_PROPERTY ('TEXT_ITEM', CURRENT_RECORD, UPDATE_ALLOWED, PROPERTY_TRUE);
SET_ITEM_INSTANCE_PROPERTY ('TEXT_ITEM', CURRENT_RECORD, NAVIGABLE, PROPERTY_TRUE);
END IF;



Thanks and regards!

That code doesn't set visual_attribute at any point.

The same way you set other properties. You do need to have some visual attributes set up. Form builder help describes all this in detail - have a look.

Jean,
Quote:
SET_ITEM_PROPERTY ('TEXT_ITEM', BACKGROUND_COLOR, 'r214g214b214');
 ELSE
 SET_ITEM_PROPERTY ('TEXT_ITEM', BACKGROUND_COLOR, 'r255g255b255');

This code will set the background_color for all instances of the TEXT_ITEM object. Like CookieMonster stated, you want to create a Visual Attribute object (in the Visual Attribute node of the Object Navigator) for each background color and then use the Set_Item_Instance_Property() built-in to set your different background colors.
