How can I filter a list form??...

demi222 · 2005-07-20

I have Table A which has the following fields:

Code of type code 10
Description of type text 30
G/L Account Number with table relation to "G/L Account"."No."

The Primary key is Code and G/L Account Number.

so...this can be an example of some records:
Code........................Description........................G/L Account No.
EEEE...........................Description of EEEEE............12345678
EEEE...........................Description of EEEEE............33333333
EEEE...........................Description of EEEEE............55555555
FFFF............................Description of FFFFFF.............9999999
FFFF............................Description of FFFFFF.............8888888

I have made a List form from Table A which shows only Code and Description. This form is the LookupFormID for Table A.

On another form, I have a Textbox with a TableRelation to Table A, which has a source expression CCC, which is a Global Variable of text 30.

Now...

When I click on the Textbox's lookup button I want the List to show up without repeating ...for example...
I would want from the above the following to show up:
EEEE...........................Description of EEEEE
FFFF............................Description of FFFFFF

what shows up now is:
EEEE...........................Description of EEEEE
EEEE...........................Description of EEEEE
FFFF............................Description of FFFFFF
FFFF............................Description of FFFFFF

Is this possible? Can anyone help me?

The best way is to create a new table - Table B - with fields Code and Description.
In table A you will use a TableRelation for filed Code using Table B.
The SourceTable for List form will be the new table (Table

.

Another way is to use temporary table in the List form.

I don't want to have to make another table... how could I do it with a temporary table?

s.delikostov · 2005-07-20

IF TableA.FIND('-') THEN REPEAT
  TableATemp.RESET;
  TableATemp.SETRANGE(Code,TableA.Code);
  IF NOT TableATemp.FIND('-') THEN BEGIN
    TableATemp.INIT;
    TableATemp.TRANSFERFIELD(TableA);
    TableATemp.INSERT;
  END;
UNTIL TableA.NEXT = 0;

FORM.RUNMODAL(ListForm,TableATemp);

  if TableA.FIND('-') then
  repeat
    TableA.MARK := true;
    TableA.SetFilter(Code,TableA.Code);
    TableA.Find('+');
    TableA.SetFilter(Code);
  until TableA.Next=0;
  TableA.MARKEDONLY := true;
  FORM.RUNMODAL(0,TableA);

Another solution is to fill temp. table in same manner and show this virtual table. But BEST is (if something other is not problem than) - split the tables>

Table A: Code + Description
Table B: Code (linked to table A), G/L Account No. (Linket to GL Acc.), Description (lookup flowfield to table A)

than you can made lookup to table A and you have correct list...

which trigger do I put this code in?

s.delikostov · 2005-07-21

In the button where you run the List form

kine · 2005-07-21

Or in OnLookup trigger... or you can modify it to work with Rec and insert it into the lookup form OnOpen... (without the FORM.RUNMODAL line)

s.delikostov,
According to your code, TableA is a record variable to my table and TableATemp is a temporary record variable to the same table.
When I do TableATemp.SETRANGE(Code,TableA.Code) the first code is Rec.Code right?
Well... I tried this, and it didn't work... it didn't show the ones it is supposed to show. if there were
Code...........Code Description........G/L Account
AAA ............. AAA description........12344
AAA...............AAA Description........33333
BBB...............BBB Description........44444
BBB...............BBB Description........55555
CCC..............CCC Description........66666

It only showed CCC nothing else.

KINE,
I tried yours...
TableA is the temporary record variable of my table right? When I do
TableA.SETFILTER(Code,TableA.Code) the first code is Rec.Code right?
The second SETFILTER you have only has Code in it... that isn't right...???
Should it be the same as the first SETFILTER?

s.delikostov · 2005-07-21

Before
FORM.RUNMODAL(ListForm,TableATemp);

add the line:
TableATemp.RESET;

kine · 2005-07-21

The construction

    TableA.SetFilter(Code,TableA.Code);
    TableA.Find('+');
    TableA.SetFilter(Code);

means, skip all next records with same Code as Now and than clear this filter... TableA.Next then go to next code...

Oh, sorry, correction, the line must be

    TableA.SetRange(Code);  //SetRange instead SetFilter...

Ok.. now it works... but something else is different now.

I have a Textbox with SourceExpression lalala which is type Text 30
and it has a Table relation to Table A....

Now, when I click the lookup it opens the list form just as I wanted, but now, it doesn't let me double click on the item I want it to show.

Before I put the code on the OnLookup trigger, it showed me everything, and I would simply double click on the one I wanted, and it would show it.

How can I make that work again?

try to use this construction:

  if FORM.RUNMODAL(0,TableA) = Action::LookupOK then
...

demi222 · 2005-07-22

Before, when the List form opened, and I chose one of the items and double clicked,
it would then put the rest of the information I wanted in the table box I have below the lookup text box...

Now, do I put the code I had OnAfterGetRecord in the OnLookUp trigger?

kine · 2005-07-22

In OnLookupTrigger is common C/AL structure this:

  <set filter to record (for example TableA)>
  TableA.SETRANGE("Field 5532",'VALUE I WANT');
  if FORM.RUNMODAL(0,TableA) = Action::LookupOK then begin
    <use TableA to read the selected record and assign values you need>
     VALIDATE("Field 1", TableA."Field 123");
  end;
