it's known silverlight lacks compelling x:type markupextension (markupextension is not supported in silverlight @ all). there dynamic workaround it? what enums ( x:static )? my need have commandparameter set type or enum value, neither of these supported in silverlight! this has done in code-behind. if build custom object exposes property of type type, not "converted" when set via xaml. this limitation prevents creating things custom enumvalueprovider, exposes type property , updates values properties enum values specified enumeration type. having class allow bind combobox or listbox list of enumeration values in xaml. you can create custom typeconverter above type property, work around issue. don't xmlns resolution you'd expect. depending on situation, may enough. here another example , exposes "known" types via properties, can bind to.

i've got app pulls xml web, , caches locally. parsing xml expensive compared parsing android binary xml, i'd store local copy android binary xml. haven't spotted api creating android binary xml on fly though, c/c++ code used aapt. my motivation taking approach don't use xml values/attributes, may want use more of them in future version of app, , don't want download xml data again. can point me @ right bits of api create android binary xml @ run-time? many thanks, phil lello android binary xml faster because optimized compiler. in runtime, can't create binary xml without having implementation of compiler you.

i reading jqfundamentals weekend, , rebecca murphey talks about: the $.fn.detach method extremely valuable if doing heavy manipulation element. in case, it's beneficial $.fn.detach element page, work on in code, , restore page when you're done. i have table sort this, got "learning jquery", page 140: var rows = $table.find('tr:not(:has(th))').get(); rows.sort(function(rowa,rowb) { ... }); $.each(rows, function(index,row) { $table.children('tbody').append(row); }); i wonder if should detach table , reattach it? detaching element removes dom. so, if detach the table element, whole table disappear or "flash" until re-insert table dom. however, may want detach tbody element dom , reinsert table when done sorting rows.
