I'm still confused about what it is you are asking. Are you saying that when the timer on page1 fires it refreshes the grid on page 3 and you don't want it to? Also why are you opening the table Trans1 in this code (it will be openned by the SELECT statement)?

Here's a little clean up of your code to make it a bit more efficient

Move the following code into the form's Init or Load event.

SET SAFETY off
SET CENTURY on
SET DATE BRITISH
SET TALK OFF
SET STATUS off

Now we can get rid of the variable and use the property directly and save a clock tick. We can also speed things up a bit by using the WITH/ENDWITH constructs.

*event timer
If Not Used('trans1')
    USE trans1.dbf Alias trans1 Again In 0 Shared
Endif

SELECT trans1
WITH ThisForm.pageframe1.page1
  IF EMPTY(.text4.value)
    .Grid1.visible=.f.
  ELSE
    WITH .Grid1
      .visible=.t.
      SELECT  TAlias1.time1,TAlias1.date1,TAlias1.roomno,TAlias1.place1,TAlias2.mobile,TAlias2.tel,TAlias2.empname, TAlias1.discerror,TAlias1.sno ;
        FROM trans1 TAlias1, emp1 TAlias2 ;
       WHERE  TAlias1.empno = TAlias2.empno   ;
         AND TAlias1.fexerno=val(ThisForm.pageframe1.page1.text4.value) AND mark1=0;
    ORDER BY date1,sno ;
        INTO table TAlias1
