wpf - Binding from trigger to object in Collection -

i have object these properties:

islightonval collection 2 fields: string state name , bool value, can see in 2nd picture:

in controltemplate of object, want create trigger for: when value of first object in collection true, this....

i can access property islightonval1 , islightonval1 of 1st picture, cannot access collection.

so working fine:

<trigger property="islightonval1" value="true"> <setter property="foreground" targetname="tkvalue1" value="{staticresource amber}"/> </trigger>

but when seek collection, never have access, tried:

<trigger property="{binding islightonval[0].value, relativesource={relativesource ancestortype=namespace:myobject}}" value="true"> <setter property="foreground" targetname="tkvalue1" value="{staticresource amber}"/> </trigger>

but trigger's property doesn't seem take binding...

anyone have solution?

regular triggers meant used on ui element properties. if want base of operations trigger on bound value need utilize datatrigger

<datatrigger binding="{binding islightonval[0].value, relativesource={relativesource ancestortype=namespace:myobject}}" value="true"> <setter property="foreground" targetname="tkvalue1" value="{staticresource amber}"/> </datatrigger>

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...
