问题 Is usage of events considered bad and all UI logic should be implemented via commands when using MVVM pattern? 回答1: It is worth thinking about what the MVVM pattern really gives you. Seperation of concerns (which is true for all UI patterns) Unit testing of view logic, by executing the view-model without the view. Developer-Designer workflow, allowing designers using Blend to work on the same code. If handling UI events in code behind doesn't prohibit the above, then there is no problem!

问题 The issue is this: Most things I read on the web says that we should avoid actions when creating popup menus because the command framework allows for more decoupling. Example: http://wiki.eclipse.org/FAQ_What_is_the_difference_between_a_command_and_an_action%3F Fair enough. But I am having a heck of a time getting the command framework to add my menu when I right click on a .java file inside the editor, and only when I click inside the editor. I can get the menu to show (using 'with' and the

问题 I asked this question before but don't think I really explained it properly based on the answers given. I have a file named backup.xml that is 28,000 lines and contains the phrase *** in it 766 times. I also have a file named list.txt that has 766 lines in it, each with different keywords.
