Dropdown system limitation

Hi Experts,

I was able to create a dropdown using Mr Pradeep Goli's instructions adopted for Java.

[disabling value help forms;

I inserted the dropdown inside a table of 20 lines. Each dropdown contains around 1500 choices. There is also another table of 20 lines with another dropdown with around 3500 entries. This causes a timeout error.

Is this a system limitation or is there another way I can get around this with that much number of entries?

Cheers,

Alfonso

    Do you really need that many entries in a drop-down? Even 150 is a lot to go through. 3500 is just plain ridiculous.There are better ways to handle that sort of thing.

      +1 (Agree with Chris Solomon)

      You'd better look for another approach.

      1) Interface should be usable and not just "be". It is obvious that user (if he/she is not absolutely dumb) will use keyboard typing to at least position himself to the correct range in such a long list. IMHO, that means that simple keyboard entry field with additional check script can do the same job as you need.

      2) At the same time, what 3500 is (e.g. 5 x 7 x 100) so you can split your list into three with 5, 7 and 100 records at a time. Maybe. Hope so. 😊

    Hello Chris and Petr,

    I actually agree with both of you. But like you said, the user is insisting on this feature. If I can tell them that this is impossible due to system constraints, they'll stop insisting for sure.

    In any case, other than a dropdown list, what else can I do to implement a field with thousands of possible entries?

    Petr,

    Where can I see documentation on the solutions you proposed? All of the documents I have on AIF is very basic and doesn't tackle such topics.

    Cheers,

    Alfonso

      Hi All,

      Thanks for the ideas. That should be enough to convince the users not to push for this feature.

      Thanks and Best Regards,

      Alfonso
