Global .NET standards

  1. .html or .aspx files only
  2. aspx files have proper DTD – document type declaration
  3. naming - container aspx file and content html component have identical name
  4. naming should be "Capability_purpose.suffix", for example popups are PU_SecurityView.html, Entity_CompanyContacts_Detail.aspx
  5. comments section at the top of every file
  6. overall HTML architecture (html, head, body, form etc)
  7. proper indentation of code
  8. XHTML compliance – closing slashes on images, input, br, etc
  9. one form tag per page right after body tag
  10. No name or ID attribute on form elements
  11. links are absolute
  12. image files use appropriate names: img, icon, btn, nav, text
  13. image tags contain alt, width and height attribute
  14. javascript tags: language and type attributes, variable declarations explicit as var, one statement per line, end lines with semicolon, proper indentation
  15. no changes to CSS by off- site resource – changes must be made with UI collaboration
  16. page weight 35K
  17. no horizontal scrolling at resolutions 800 X 600 or 1024 X 768
  18. browser support IE 5.0 – 8.0
  19. "super-set" html content component should have discreet easily hidden components, as stacked tables or TR for conditional rendering – TD will not work for this
  20. All lists should be width="100%"
  21. % should not be used on any TD (Except snapshot page template)
  22. Styles should NOT be used on the TD for any cell containing inputs, selects or required asterisks – use span instead on the text in question or assign the class to the input itself.

Visual Studio IDE Shortcut Keys

My favorite Visual Studio keyboard shortcuts
  • CTRL+ALT+L: View Solution Explorer. I use Auto Hide for all of my tool windows to maximize screen real estate. Whenever I need to open the Solution Explorer, it's just a shortcut away. Related shortcuts: CTRL+ALT+X (Toolbox), F4 (Properties), CTRL+ALT+O (Output), CTRL+\, E (Error List), CTRL+\, T (Task List).
  • F12: Go to definition of a variable, object, or function.
  • SHIFT+F12: Find all references of a function or variable.
  • F7: Toggle between Designer and Source views.
  • CTRL+PgDn: Toggle between Design and Source View in HTML editor.
  • F10: Debug – step over. Related debugging shortcuts: F11 (debug – step into), SHIFT-F11 (debug – step out), CTRL-F10 (debug – run to cursor). F9 (toggle breakpoint).
  • CTRL+D or CTRL+/: Find combo (see section on Find Combo below).
  • CTRL+M, O: Collapse to Definitions. This is usually the first thing I do when opening up a new class.
  • CTRL+K, CTRL+C: Comment block. CTRL+K, CTRL-U (uncomment selected block).
  • CTRL+-: Go back to the previous location in the navigation history.
  • ALT+B, B: Build Solution. Related shortcuts: ALT+B, U (build selected Project), ALT+B, R (rebuild Solution).
  • CTRL+ALT+Down Arrow: Show dropdown of currently open files. Type the first few letters of the file you want to select.
  • CTRL+K, CTRL+D: Format code.
  • CTRL+L: Delete entire line.
  • CTRL+G: Go to line number. This is useful when you are looking at an exception stack trace and want to go to the offending line number.
  • SHIFT+ALT+Enter: Toggle full screen mode. This is especially useful if you have a small monitor. Since I upgraded to dual 17" monitors, I no longer needed to use full screen mode.
  • CTRL+K, X: Insert "surrounds with" code snippet. See Snippets tip below.
  • CTRL+B, T: Toggle bookmark. Related: CTRL+B, N (next bookmark), CTRL+B, P (prev bookmark).
