c# - multiple uses of attached property does not work -

-

my guess i'm not understanding attached properties correctly. i'm trying convert flowdocument on richtextbox html string property in view model. have 2 richtextboxes using richtextboxassistant class (thanks this blog post):

<richtextbox x:name="rtb_description"      local:richtextboxassistant.bounddocument="{binding myvm.description,         validatesondataerrors=true}"/>  <richtextbox x:name="rtb_descriptionhowto"     local:richtextboxassistant.bounddocument="{binding myvm.descriptionhowto,         validatesondataerrors=true}" />

in richtextboxassistant class, have dependency property:

public static readonly dependencyproperty bounddocument =     dependencyproperty.registerattached(         "bounddocument",         typeof(string),         typeof(richtextboxassistant),         new frameworkpropertymetadata(             null,             frameworkpropertymetadataoptions.bindstwowaybydefault,             bounddocumentchanged         )     );

the problem bounddocumentchanged method gets hit when change value in first richtextbox, rtb_description, not when change value in rtb_descriptionhowto. when change text or rtb_descriptionhowto, never reach bounddocumentchanged. result of richtextboxassistant being static class? how can fix can use richtextboxassistant multiple richtextboxes?

coline had right idea: tried removing attached property first richtextbox, , changing value of second richtextbox still didn't put me in bounddocumentchanged. turns out descriptionhowto property in view model null, instead of html string. when initialized @"<html><body></body></html>", things started working.

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
