Question

我在水平行中有多个复选框，并且为内容保留的空间保留了很多空间。如何隐藏内容？

将Content Null设置为空，将其设置为空网格：

        <Style x:Key="RbNoContent" TargetType="RadioButton">
            <Setter Property="ContentTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <Grid>
                            <!--Somehow need to stick Content={TemplateResource Content}-->
                        </Grid>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
        </Style>

我添加单选按钮的代码

            for (int i = 0; i < options.Count; i++)
            {
                var option = options[i];

                ColumnDefinition columnDefinitionRadioButton = new ColumnDefinition();
                columnDefinitionRadioButton.Width = new GridLength(1, GridUnitType.Star);
                grdRadioButtons.ColumnDefinitions.Add(columnDefinitionRadioButton);


                RadioButton radioButton = new RadioButton();
                radioButton.Tag = option.ID;
                radioButton.GroupName = groupGuid.ToString();
                radioButton.VerticalAlignment = VerticalAlignment.Center;
                radioButton.HorizontalAlignment = HorizontalAlignment.Center;
                grdRadioButtons.Children.Add(radioButton);
                Grid.SetColumn(radioButton, i);
            }

那就是它的样子：

根据您的要求，您需要自定义RadioButton样式并隐藏ContentPresenter零件，然后使椭圆水平居中。我已经创建了可以直接使用的完整样式。

<Style x:Key="RadioButtonStyle1" TargetType="RadioButton">
    <Setter Property="Background" Value="{ThemeResource RadioButtonBackground}"/>
