Look at 'set_item_property'. But what do you mean by 'disable' a button? Try the 'visible' property. But I have this doubt as to whether you can 'disable' a button but I can't see it in the documentation.

SET_ITEM_PROPERTY('BLOCK_NAME.button_name', label, 'you_label');
SET_ITEM_PROPERTY('BLOCK_NAME.button_name', visible, property_false);

regards.

Yes you can. I've attached a small example.
For those unable to download it: The form consists of
- an alert MYALERT
- a control block CTRL
- a push button PB_ENABLE_DISABLE with label 'Disable'
- a push button PB_NOTHING with label 'Nothing'

PB_ENABLE_DISABLE will switch the enabled property of push button PB_NOTHING. PB_NOTHING will show myalert.

Button PB_ENABLE_DISABLE has the following code:

Begin
	If Get_Item_Property('CTRL.PB_NOTHING', ENABLED) = 'TRUE'
	Then
	  Set_Item_Property('CTRL.PB_NOTHING', ENABLED, Property_False);
	  Set_Item_Property('CTRL.PB_ENABLE_DISABLE', LABEL, 'Enable');
	Else
	  Set_Item_Property('CTRL.PB_NOTHING', ENABLED, Property_True);
	  Set_Item_Property('CTRL.PB_ENABLE_DISABLE', LABEL, 'Disable');		
	End If;
End;

Button PB_NOTHING has the following code:

Declare
	pb PLS_INTEGER;
Begin
	pb := Show_Alert('MyAlert');
End;

Granted, quick and dirty but it demonstrates the use.
