Question

我正在使用WPF Extended CheckComboBox。我在app资源中有一个模板，我在其中修改了一些样式选项，但是我找不到如何更改复选框颜色。

有人有想法吗？

这是我正在使用的模板：

<Style x:Key="CheckComboBoxStyle1" TargetType="{x:Type xctk:CheckComboBox}">

CheckBoxes没有特殊的风格。您可以通过向CheckBox添加隐式CheckComboBox样式来设置这些样式：

<xctk:CheckComboBox>
    <xctk:CheckComboBox.Resources>
        <Style TargetType="CheckBox">
            <Setter Property="Background" Value="Yellow" />
        </Style>
    </xctk:CheckComboBox.Resources>
</xctk:CheckComboBox>

CheckComboBox框颜色
