radio-button

问题 I have a property of type boolean presented with checkbox. I want to change that to two radiobuttons that bind on the same property presenting the value true/false. How can that be done? 回答1: <RadioButton GroupName="Group1" IsChecked="{Binding PropertyValue}" Content="Yes" /> <RadioButton GroupName="Group1" Content="No" IsChecked="{Binding PropertyValue, Converter={StaticResource BoolInverterConverter}}" /> public class BoolInverterConverter : IValueConverter { #region IValueConverter Members

问题 I am using a TableLayout with TableRows as my main activity. Inside the TableLayout is a Radio Group containing 2 Radio Buttons inside the activity (the Radio Group being inside a table row). I want to be able to align the rightmost radio button to the right edge screen, so the "gap" is between the left radio button and right button (instead of after the right radio button). i.e. So instead of having | (x) (x) gap | I will have |(x) gap (x)| where (x) are the Radio Buttons and | are the edges

问题 I have a project that requires some values to get updated with JavaScript from an HTML radio change event. For some reason in IE, it seems that the onchange event isn't called until the radio has lost focus. Unfortunately due to the way the code is setup, I can't use the click event and have to use the change event. Does anyone know of a way to force IE to raise the change event as soon as the check is changed rather than when it looses focus? Thanks. 回答1: Just to add, you can force IE to

问题 I'm wondering if there's a way to move the label text of a radiobutton to a different area, e.g. below the actual button. Below is an example of a few radiobuttons being placed using grid that I'm using: from tkinter import * from tkinter import ttk class MainGUI(Frame): def __init__(self, parent): self.parent = parent Frame.__init__(self, parent, background="white") self.mainframe = ttk.Frame(root, padding="8 8 12 12") self.mainframe.grid(column=0, row=0, sticky=(N, W, E, S)) self.mainframe

问题 I am trying to put a letter inside a radio button (with Materialize framework) like the A and B in this image. How do I do this? 回答1: You cannot do that. But instead, you can make something similar using CSS: label {display: block; padding: 5px; position: relative; padding-left: 20px;} label input {display: none;} label span {border: 1px solid #ccc; width: 15px; height: 15px; position: absolute; overflow: hidden; line-height: 1; text-align: center; border-radius: 100%; font-size: 10pt; left:

问题 I'm having a problem with nested model forms that contain radio buttons, when I have multiple models all the radio buttons are treated as being in the same group. My model contains a has_many relationship like this: class Order < ActiveRecord::Base has_many :order_items accepts_nested_attributes_for :order_items end Class OrderItem < ActiveRecord::Base belongs_to :order end I then have a partial that creates the OrderItem model form using <% fields_for "order[order_items_attributes][]", order

问题 I have an app that uses radio buttons. The default for this button is set in the main.xml file, ie: android:id="@+id/rb_sat1E" android:checked="true" In the Java file I have: final RadioButton radio1 = (RadioButton)findViewById(R.id.rb_sat1E); I have also created a 'Reset' button in the main Java file and can use the following code to reset TextView information ie. pos1_deg.setText("0.0"); But how do I reset a radio button? I would have thought it to be something like radio1.setBoolean("TRUE"

问题 I want to have the "label", - the text you set in your RadioButton to show left of the button and have some padding in between. Adding an additional TextView into the layout doesn't work because my RadioGroup does not work (i can choose multiple buttons) if i add anything other then a RadioButton into the RadioGroup . So, how can i change the RadioButton to be <text><buttondrawable> instead of <buttondrawable><text> 回答1: You can achieve this by setting android:button="@null" and adding the
