radio-button

问题 I have a radio button group in Android. I receive events when the items are selected. Normal so far. But I don't get the event if the user clicks on an already selected item.

Thanks a lot. 回答1: i don't understand why you would get an event when clicked on an already checked radio button, but if you want to unselect a radio button by a click on it if it is already selected!! check

问题 I'm attempting to change the border color of a radio button label when it is selected in the form. I found this question which is pretty much exactly what I am looking to do: CSS - How to Style a Selected Radio Buttons Label? but when I try it with my own code the color doesn't change on select. This is driving me nuts, I can't figure out why it won't apply the border color - any help is very much appreciated. I have uploaded the code I am working with here: http://jsfiddle.net/SHfr5/ but I

问题 I am developing a page for rating questions.

问题 I use code with Radio Button (see last code) to insert a new row into row 15, which pushes the old data down, and at the same time, copies the same formulas into row 15 that were once there (in row 15) before the button is clicked. Once the button is clicked, I can enter 3 digit data into E15, then hit enter, and all formulas calculate across row15, based on what is entered in E15. Now I love how the code performs, but for some reason, the formula in CG15 changes from =IF(CF15=1,IF(CF15<>""

问题 In my android application, I need to disable radio group in xml layout. I searched, but I found only through pro-grammatically not in xml layout.

问题 I am trying to find out how to make a radio button in XAML - I see there is a way to do it in android but was wondering if there is a simple cross platform way to do it without needing additional nuget packages. 回答1: Up to my findings, there is no any in-built Radio button in Xamarin. Directly to your answer @Sparkz, there is method to build custom Radio button, but it is using other nuget packages to implement it. I also had the same problem, but I used xamarin Picker in my project instead
