How to disable (grey out) button in report

Question

Hi,
Can any one; pls help how to disable button (grey out) on some specific condition.
I have a report of 2 pages; In first page it displays few records; once click on specific record control goes to next page 2; And here i have button (template based button); Once click on this it perform pl/sql procedure.
My requirement is: The button should disable (should not hide) when moves from page 1 to page 2 based on some specific returned values in page 2.
I have return code in button conditions (Condition type = PL/SQL Function Body Returning a Boolean)
Sample code is:
if :value1 = 'disable_test_value' then
return false;
else
return true;
end if;
The above code is working fine with button completely disappers if the :value1 = 'disable_test_value' (which is suppossed to be as we gave return false).
My question is: Is there any way; we can still show button (but button disabled or grey out; so that no action can perform on this button )? And also show some text message in other text field when button is disabled?
Thanks!!

I have an example: http://apex.oracle.com/pls/otn/f?p=27168:1 using theme #2. You need to use a theme that has a "grayed-out" alternate button template.
To accomplish this I:
1) Created one item named P1_VALUE1 to contain the condition as to whether the button should be enable ("enable_test_value") or disabled ("disable_test_value").
2) Created an enable button with a "Button Style" of "Template Based Button" with "Button Template" value of "Button". I had the "Condition" type of "PL/SQL Function Body Returning a Boolean" to be:
if :p1_value1 = 'disable_test_value' then
return false;
else
return true;
end if;I had the "URL Target" to be: javascript:alert('Performing function ...');
3) Create a disabled button with "Button Style" of "Template Based Button" with "Button Template" value of "Button, Alternate 3". I had the "Condition" type of "PL/SQL Function Body Returning a Boolean" to be:
if :p1_value1 != 'disable_test_value' then
return false;
else
return true;
end if;I had the "URL Target" to be: javascript:alert('Performing function ...');
