Auto Complete Entry Field

[Quinn Rayen]

Hi,

We have a requirement to have an auto complete entry field to pick up address from the list. Initially the list will be blank, once the user starts entering some text, need to populate the filtered address list retrieved from a third-party URL.

I am unable to use the auto complete option field as the initial list is empty I cannot type a word in it.

Please advise the options available to implement this.

Thanks

Regards

Quinn

Hi,

 

Try using the BufferChanged event on a separate entry field and dynamically populate a separate option field?

 

You will get an event for each key press.

 

I have not tried the BufferChanged with option field style set to OF_EDITABLE , but I would give it a go until Bodo says it doesn’t….

 

Good luck

 

Adrian

An OptionField does not have a BufferChanged event, so you would have to use it on an EntryField and have an additional ChoiceField (OptionField/ListField) to provide the value list the user can pick from.

Kind regards,
Bodo.

Hi Quinn,

Here is a link to a generic procedure developed by Gary Hansford.  It was designed for a customer lookup tool for support staff to locate a customer among 6 million entries in the database.

https://groups.google.com/g/openroad-users/c/ry7EeG5EEkE/m/pQ8aSZpFwToJ

I also have some examples which lookup to a tablefield and reposition the highlight based on the entry in a filter column.   If these sound useful, please send me a message direct.

Cheers
