getting twine sets display layer

we're operative an home information component being combined c# controlling nhibernate map objects database. mvc settlement being used removed business explanation ui. here problem,

how non-static sized opposite set strings ui?

for instance contact vigilant have ability named city binds city hit lives. republic app combined some-more 80 cities. those cities combo box? (or information grid, tables, ...) instance city array fixed. there need supplement another city enlarged time. (if city list changes, recompiling problem)

for instance contact vigilant have another ability named foobar going reason 1000 opposite twine values values going comparison combo box property. set grown users want. bucket combo box values? (if twine list statically combined combo box object, recompiling problem)

i have opposite solutions below

1. all twine values statically combined combo box formula designer


2. get values apparatus file


3. write those values an xml record (actually same above, nonetheless need recompile)


4. make city vigilant values list city list nhibernate


5. make category named stringholder type value property. twine values(including city foobar) combined only list named stringholder. those values pivotal "city" "foobar" nhibernate.

which choose? advise me another one?

thanks all
