Combobox Drop Icon?

Classic Servoy

Why should some of my combobox’s show the drop down image arrow and some not?

I’ve checked the settings on those that do and those that dont and I cant determine what makes one show the image and another not?

What’s the criteria? :?

Further Investigation has revealed that if there are two column criteria selected in the Valuelist (even if its the same column selected twice), then the drop down arrow does not appear on smart client forms - though they do on web client.

If a single column is selected in the valulist then the arrow appears in both clients?

Can this be by design? :?

I really need the columns to appear consistant in the smart client - all showing or all not showing.

I noticed that I can use the drop down functionality in a TEXT_FIELD without making it a COMBOBOX too (with a valulist added)! This works in smart client but not web client - though it has the advantage of not showing the drop arrow at all it needs to be web client compatible for my purposes unfortunately.

Any thoughts :?:

what do you mean with 2 column criteria? 2 display dataproviders in the valuelist?

this shouldnt matter at all. Are you saying that you sometimes in the smart client dont see that drop down arrow?
If you use a combo you always should see that.

what kind of os are you on? Because it could be platform specific.

a type ahead (textfield with valuelist) should work fine in the webclient. If that isnt the case then you should make a case in our support system.

Thanks for the response Johan - if I have two criteria in the value list (one saved in the Db and a different one displayed) then I dont see the drop down arrow.

isnt the change that you see just between an editable or none editable combobox?

in an editable you have sort of a drop down icon, but that you also should see on a none editable but then the complete thing is a drop down.

if you have different return as display values then yes the combobox will be readonly

Thats pretty much the answer I was looking for Johan

  1. If a combobox is based on a valuelist with two criteria then its non-editable (even if the properties say it is)
  2. The drop down icon indicates if the combo is editable or not.

I might be wrong but I don’t think that’s explained any place in the docs???
