问题描述

在我的 Visual Studio 2010 C# WPF 应用程序中，我有 7 个选项卡与交替的 colors 这是我的客户需要的。 他们不喜欢用鼠标悬停在选项卡上并更改选项卡的背景颜色，即使选项卡没有被选中。

Dialog 的部分 WPF XAML 代码如下所示：

 .
 .
 .
 <TabControl Width="auto" Height="auto" Name="MyTabs" SelectionChanged="MyTabs_SelectionChanged">
    <TabItem Header="Tab 1" >
       <TabItem.Resources>
          <Style TargetType="{x:Type TabItem}">
             <Setter Property="Background" Value="LightGreen"></Setter>
          </Style>
       </TabItem.Resources>
 .
 .
 . Tab Contents
 .
 .
 .
    </TabItem>
 .
 .
 .
    <TabItem Header="Tab 2" >
       <TabItem.Resources>
          <Style TargetType="{x:Type TabItem}">
             <Setter Property="Background" Value="LightBlue"></Setter>
          </Style>
       </TabItem.Resources>
 .
 .
 . Tab Contents
 .
 .
 .
    </TabItem>
 .
 .
 .
 </TabControl>

如果我不更改选项卡背景 colors，则没有问题。 但是，对于最终用户而言，具有颜色的选项卡有助于特定应用程序。

我的问题是，当我需要为 WPF 选项卡设置自定义背景 colors 时，如何不使用鼠标将鼠标悬停在选项卡上时更改选项卡颜色？
