[NO, some field types are compatible] Will changing field type corrupt values?

hi there,

[i have a question]
If I change the type of a field, will I loose or corrupt values that were already input?

[in more detail]
My live-site has a field of type 'checkbox'. current config is: 1::yes%% .
Problem: Client needs category-page with filtering; filtering needs to offer 'any', 'yes', 'no'.
But current filter on category-page is set to 'dropdown-selector' and of course only offers 'any' and 'yes'.

Although I assume, that changing my checkbox into a radiobuttons-group with a config like: 1::yes%%0::no%% would work, but now above question arises: "Will that do something bad to my data?"

Thank you a lot and sorry for this lengthy question

Hello

changing field type will
- maintain all common paramaters (e.g. "Required")
- also the fields have compatible values:
select, selectmultiple
radio, radioimage
checkbox, checkboximage

* but note that adding / removing into a fieldgroup: selectmultiple, checkbox, checkboximage into a fieldgroup, will distribute their values across the fieldgroups

so you can change the fieldtype without problem,
just in your case you may not need to change the field type ??
- the way that the field's filter is displayed is another parameter inside the "Filtering" TAB

first, thanks for your lightning-fast reply!

>> the way that the field's filter is displayed is another parameter inside the "Filtering" TAB
yes, but in my case I seem to have a discrepancy between field editing and filtering:
- editing currently allows 'yes' or ~no checkbox checked.
- filtering currently allows 'any' or 'yes'.
In other words: I can't filter what my field doesn't know about, right?

- filtering should allow 'any', 'yes' and 'no'.
My approach would be to add 'no' to the field's editing config, making it necessary to change it's type to radiobuttons (client doesn't like dropdown).
Or are you saying there is a way to interpret '~no checkbox checked' (in editing) as 'no' in the filters, while still telling the difference from 'any'?
