问题 I need a button-like control that can have a Checked property, so that when clicked it stays pressed. I had that functionality in WinForms, with the CheckBox control, setting the Appearance property to "Button". Can someone help me? 回答1: Use a ToggleButton, it has all the functionality you see in a CheckBox since it is derived from it. 回答2: WPF has a built-in ToggleButton control that serves this purpose. If you need to change the visual appearance of this default control you will need to

问题 Right guys. I need your brains as I can't find a way to do this properly. I have a view model: public class EditUserViewModel { public User User; public IQueryable<ServiceLicense> ServiceLicenses; } User is unimportant as I know how to deal with it.

问题 I have a component that contains some checkboxes.

问题 I am using Bootstrap. I have a table with a checkbox in a header and in each collumn. I am trying to make "check all" functionality on jQuery, but it seems that bootstrap does not use checked attribute. As I see, it adds span tag around my checkbox and adds a class 'checked' to it.

Any other suggestions deal with multiple child checkboxes and solves the problem by watching on them. 回答1: http://jsfiddle.net/xJhEG/ I made it in a
