XAML 如何在WPF中将组合框的可编辑文本框的背景设置为透明而不使文本透明？

我想将组合框的可编辑文本框的背景设置为透明。我可以通过编辑控件模板<SolidColorBrush x:Key="ComboBox.Static.Editable.Background" Color="Transparent"/>来实现这一点。但是，当我这样做时，选定项的文本不再出现在组合框的可编辑文本框中。提前感谢！

我根据你的信息修改了下面的代码，没有问题：
请复制默认代码并将相应代码修改为以下代码。
更新的样式名称<Style x:Key="ComboBoxStyle1" TargetType="{x:Type ComboBox}">
装订<ComboBox Style="{DynamicResource ComboBoxStyle1}"> in the combobox

<SolidColorBrush x:Key="TextBox.Static.Background" Color="Transparent"/>

<SolidColorBrush x:Key="ComboBox.Static.Background" Color="Transparent"/>
        <SolidColorBrush x:Key="ComboBox.Static.Editable.Background" Color="Transparent"/>

这是reference document。
