Question

我想在菜单项中添加单选按钮。

我已经看到一些答案，其中人们将单选按钮作为菜单项。但我希望我的菜单项具有适当的单选按钮，可以在Winforms轻松完成。

为了确保我没有得到与其他人相同的答案，这里是菜单项的单选按钮应该是什么样子的图片：

顺便说一下，我正在使用C＃，WPF。

您可以通过更改其Template-property来更改控件的外观：

            <MenuItem>
                <MenuItem.Template>
                    <ControlTemplate>
                        <RadioButton>Radio</RadioButton>
                    </ControlTemplate>
                </MenuItem.Template>
            </MenuItem>

编辑：使用RadioButton作为MenuItem-Icon，以获得图片中显示的外观：

                <MenuItem Header="Hallo">
                    <MenuItem.Icon>
                        <RadioButton/>
                    </MenuItem.Icon>
                </MenuItem>
