restriction when navigation

[sali]

Hi, every one

On witch way I can navigate to another block when validate item without restriction

thanks..

[miritika]

can u please elaborate the question.

[sali]

I sorry miritika..

I mean, if I want to move to another block when I change the value of text item. but if I use GO_BLOCK in WHEN-VALIDATE_ITEM trigger the compiler return restriction.

How can I do that ..
Thanks ..

is POST-TEXT-ITEM also restricted?

In order to move to another block when the value of item is changed, you must use the when-new-item-instance trigger of the next item in the sequence of items in the block or the when-new-record-instance trigger in the case the item is the last in the record and the proprety navigation sequence of the block is next record, and finially, the when-new-block-instance trigger if the navigation sequence is next block

Bye, Rayd

Hello,

In POST-TEXT-ITEM you can not use restricted built ins.
All navigational built ins are restricted built ins.

In Key triggers you can use restricted built ins.

Example :
In KEY-NEXT-ITEM Trigger
--------------------------------
if < Condition > then
Go_Block('Block Name');
end if;

Hope this will help u .

KEY-NEXT-ITEM Trigger is not fired in cas of mouse navigation, isn't it?

Hello,

Yes u r absolutely right.

[sasmita]

Hello,

U can go in two ways :
First one is :
U can go for two trigger at the block level
Example :
One is :
In KEY-NEXT-ITEM Trigger
--------------------------------
if < Condition > then
Go_Block('Block Name');
end if;

Second is :
In WHEN-MOUSE-CLICK Trigger
--------------------------------------
if < Condition > then
Go_Block('Block Name');
end if;

This will solve both from key board as well as thru mouse navigation.

Second one is :
Can do like this also, then u do not have to worry about by key board or mouse navigation.

WHEN-TIMER-EXPIRED
---------------------------
DECLARE
tm_name VARCHAR2(20);
BEGIN
tm_name := Get_Application_Property(TIMER_NAME);
IF tm_name = 'MY_TIMER' THEN
Go_block('Block Name');
END IF;
END;

WHEN-VALIDATE-ITEM
----------------------------
declare
t timer;
begin
if then
t :=create_timer('MY_TIMER', 1, NO_REPEAT);
end if;
end;


Hope this will help u ..
