c# - Reverse Generated Items & Tab Order of ItemsControl Collection -


so know itemscontrol generate items top-to-bottom in itemspanel. yes can change sort order , generate them in different ways here's actual problem.

if have itemscontrol using itemtemplate multiple uielement's , use example, stackpanel itemspanel end natural tab order of like;

a. 1  2  3  4  5 b. 6  7  8  9  10 c. 11 12 13 14 15

expected, use either order of placement or flowdirection on itemtemplate get;

a. 5  4  3  2  1 b. 10 9  8  7  6 c. 15 14 13 12 11

now, question how achieve? (in efficient way) order more like;

c. 11 12 13 14 15 b. 6  7  8  9  10 a. 1  2  3  4  5

now if you're thinking.. "ugh, shift+tab dummy..." wish option. requirement using tab, , generating collection in reverse bottom top instead of top bottom , having tab order reversed while they're in control. wise try , hijack shift/tab event , convert tab somehow? if case answers part of question.

hopefully someones ran before or enjoys interesting question insight appreciated. thanks!

i tried simple example stackpanel of stackpanels (ie no data binding), , seems flow direction has no impact on vertically stacked panels (it nice if there toptobottom, or bottomtotop option).

i think data model needs (conceptually) list of lists, , need make itemscontrol of itemscontrols (i know it's pain layout can done), , you'll have order outer list backwards controls generated c, b, (because flowdirection doesn't in vertical orientation).

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
