问题 I'd like my UITableView to behave like the the table in the Contacts editor, i.e. the user should hit Edit and an "add new category" row should appear at the bottom of each section.

Also, how do I respond to clicks on the "add new category" row? The row is not clickable in my current implementation. Do I need to

问题 I saw this same question for VIM and it has been something that I myself wanted to know how to do for Emacs. In ReSharper I use CTRL-D for this action. What is the least number of commands to perform this in Emacs? 回答1: I use C-a C-SPACE C-n M-w C-y which breaks down to C-a : move cursor to start of line C-SPACE : begin a selection ("set mark") C-n : move cursor to next line M-w : copy region C-y : paste ("yank") The aforementioned C-a C-k C-k C-y C-y amounts to the same thing (TMTOWTDI) C-a

Thanks 回答1: The formatter:'actions' is not yet good documented. The current version of jqGrid 3.8.2 support some options which you need. In lines 394-466 of the jquery.fmatter.js of the current version you can see more. What you need are onEdit , afterSave (on "Submit") and delOptions.onclickSubmit parameters. To tell the truth I didn't use the

问题 I've build a custom cell with IB, and display it on a tableView , that doesn't cover the whole window. I set up a toolbar and gave it a button, which toggles the isEditing attribute and the buttons title. I also made the if(!self.editing) in the didSelectRowAtIndexPath . I get the feedback, that when the button is hit, I am in editing mode, but my custom cells don't show the delete-sign on the left. If I swipe a cell, the Delete button on the right appears, but the App crashes, if I push that

问题 What is the best way to achieve bulk editing of a grid view in ASP.net? I don't want the user to have to click edit on each individual row to change it.

Is a grid view even a good way to go about achieving this? 回答1: Try this: In you gridview create a template column with textboxs next fill all with
