Combobox & automatic change of text input?

FFF · Post by **FFF** » Thu Mar 18, 2021 8:55 am

Guys,
i use a commercial C# app, which has a combobox to enter text for searching a table.
Now, i enter e.g. "Preuss" - and the control changes this automatically to "Preuß". I enter "Preuß" and it get's changed to "Preuss", i didn't manage to find a consistent way of behaviour.
Confronted the maker and got back: "this does the control automatically, we can't influence this."
I have zero experience with Winform.Control.Combobox - can that be a valid response?

Hi Karl,
System.Windows.Forms.ComboBox contains the possibility for custom autocomplete, so it should depend on the programmer what would be to be completed.
But maybe he has used some form of a customcontrol, either 3rd party or developed by someone inhouse.

Hi Karl

No - that is nonsense.

I don't have a double s key on my keypad. Possibly something to do with your keyboard, Font settings etc.

If it was the control itself everyone using it, everywhere would have flagged up a problem.

Thx Wolfgang,
custom-autocomplete was my idea, too. I doubt this is a special implementation, as in this case it's really only used as stupid textinput...
Wouldn't have complained, but they treat my finding as "wish", while i see it as "bug" - as it controls the result of a query, so retrieving, often wrong, subsets, i think it qualifys a priority A++ B)

Sorry, Terry,
but equally nonsense

- if my keyboard would cause this, it would do this for all these controls on my machine - what's not the case.
No, i'm confident they'll fix this, was only bothererd, as they didn't seem to realize the brisance of the wrong implementation...

Hi Karl,

What happens when you enter "Franzi" ? Does it change to "Franziska", and "Franziska" changes to "Franzi" ?

Seriously: Searching for "autocomplete combobox problems umlaute" show several hits. Here´s a link that describes a similar "ss" -> "ß" problem, but no solution.

maybe one of the other hits is more helpfull ...
