Rendering subcategories on click in asp.net mvc3 -


i new mvc3, developing first project in mvc3. have left side bar filled top categories. on click of top category, want display sub categories under clicked category. subcategories can @ no of level.

  • how go it?
  • should use partial views?

on click of category, first have check if has subcategory, if yes render sub categories.

i think best option here use ajax , dynamic load of data.

on javascript code bind click event of first level nodes ajax call method on server.

this method should: check if node has children, if has return list of children associated it, if hasn't should return info adverting client code it.

your ajax call on success should check if receive list of subnodes or message adverting there's no subnodes. if has subnodes append them html structure, if hasn't nothing (or whatever want when clicking on top node without children).

from here can make system grow in complexity as want, using different methods different node levels , behaviours, etc...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
