Help validate listField.

Hello

I wonder if anyone can help me with a problem.  I have a list on a screen, but I need to validate that only can select in sequence, I appreciate if someone can help me with this problem.

Thank you.

Here's what I'd do:

1 create an object that would be responsible for the validation logic (check if the order was valid, reset validation, etc.).

2. replace the fieldChangeNotify to call the validation manager with the Index of the selected item.

3A this stage, the Manager of Validation check the source and decides what to do: let the user continue (validation completed successfully), display an error (invalid input) or do nothing and wait for the rest of the entry.

I think you should get started now.

    Hi all

    Working in Forms 10g on Windows XP.

    I have a field of type CHAR maximum length 10. When I enter some value(ex: 12T34A) in it, WHEN-VALIDATE-ITEM Tigger valid which has 2 blokcs(declare...begin...end) plsql.
    My requirement here, is if the value I entered number and length is < = 6 as 123123, so I want to skip the first plsql block and continue with the 2nd block.
    How can I check whether the value I entered number and how to write if condition say?

    Help me please...

    Well, clearly, you will need test if the entered value is numeric or alphanumeric. This is possible in boxes for the value of a NUMBER and by managing any generated errors. For example:

    DECLARE
      n_test  NUMBER;
    BEGIN
      n_test := TO_NUMBER(:BLOCK.ALPHA_NUMERIC);
    EXCEPTION
       WHEN VALUE_ERROR THEN
          Clear_Message;
          Message('Value of :BLOCK.ALPHA_NUMERIC is not a number.');
          Message(' ');
    END;
    

    To use it in your conditional statement, you can write something like the following:

    DECLARE
       n_test     NUMBER;
       b_success  BOOLEAN := FALSE;
    BEGIN
       --First test for Number Value.
       BEGIN
          n_test := TO_NUMBER(:BLOCK.ALPHA_NUMERIC);
          b_success := TRUE;
       EXCEPTION
          WHEN VALUE_ERROR THEN
             b_success := FALSE;
       END;
    
       IF ( b_success ) THEN
          -- Perform a calculation :BLOCK.ALPHA_NUMERIC value
       ELSE
          -- Do something else with the value.
       END IF;
    END;
    

    Hope this helps,
