c# - Multiple DisplayMember using special class -

i trying listbox display concatenation of multiple rows of table accommodation.

because can't edit datasource, prepared class, accommodationentity, contains both original accommodation object , string want listbox display.

however, reason, fail set displaymember property of listbox, displays default jibber-jabber.

i set listbox follows:

accommodationlist.displaymember = "texttoshow"; // load , set accommodation list<accommodationentity> relatedaccommodations = dt.listholidayaccommodation(relatedholiday); accommodationlist.datasource = relatedaccommodations; accommodationlist.refresh();

the class objects stored in datasource looks this:

class accommodationentity { public accommodation classicaccommodation; public string texttoshow; public accommodationentity(stay relatedstay) { this.classicaccommodation = relatedstay.accommodation; string = relatedstay.datefrom.tostring(); string = relatedstay.dateto.tostring(); string city = relatedstay.accommodation.location.tostring(); string hotelname = relatedstay.accommodation.name.tostring(); this.texttoshow = hotelname + ", " + city + " (" + + " - " + + ")"; } }

} `

and finally, there method searching (returning right objects):

public list<accommodationentity> listholidayaccommodation(holiday selectedholiday) { list<accommodationentity> ubytovani = new list<accommodationentity>(); var stays = singlestay in selectedholiday.stays select singlestay; foreach (stay singlestay in stays) { accommodationentity newstay = new accommodationentity(singlestay); ubytovani.add(newstay); } homecoming ubytovani; }

i know datasource contains right data, reason, seems displaymember property remains set "".

any help appreciated.

thanks.

did seek set displaymember , displayvalue this. "name"/"value" name of property in accomodation class.

list<accommodationentity> relatedaccommodations = dt.listholidayaccommodation(relatedholiday); accommodationlist.datasource = relatedaccommodations; accommodationlist.displaymember = "name"; accommodationlist.valuemember = "value";

update:

make sure texttoshow property, not public field.

c# winforms data-binding

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
