checkbox

问题 I'm using the ListView to provide a list for the user to choose from. Here is the main code: SimpleAdapter adapter = new SimpleAdapter(this,contacts, R.layout.list_contact, from_contacts, to_contacts); listview_selected_contact.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); listview_selected_contact.setAdapter(adapter); I wonder why the checkbox doesn't show?

问题 I am using a in-place editable listview control for a project. The editable listview adds a 'SubItemClicked' event so that each 'cell' can be edited. lstSD2.SubItemClicked += new ListViewEx.SubItemEventHandler(lstSD2_SubItemClicked); I also have the listview checkboxes enabled with a 'ItemChecked' event. The problem is that once the 'ItemChecked' event is enabled double-clicking on any row fires the 'ItemChecked' event and prevents the 'SubItemClicked' event from firing. Is there a way to

问题 Let's suppose: a page with some dynamically generated checkboxes outside of a form element. After the user has checked some of the checkboxes, I would love to append all those checkboxes (either checked or unchecked) into the form element so that when the user click the "submit" button, the form takes into account the checkboxes, their ids, names, data-names and their status (checked or unchecked). Is that possible ? I have tried a codpen here: https://codepen.io/anthonysalamin/pen/ZxvZpP

问题 I'm using a checkbox in Semantic UI. I would like to switch the position of the label and the input but it's proving to be kind of a pain.

问题 I have three checkboxes. Each checkbox has a 'name' and 'age' text box next to them. 'Singles' checkbox box has one set of these textboxes while 'Couples' checkbox has two sets. I'm looking for code which will provide an 'alert' message prior to submitting a form to say all textboxes must be filled in if corresponding checkbox is ticked.
