组合框鼠标悬停 [英] Combobox Mouseover

问题描述

我想要改变我的组合框背景（ mouseover ）在stackoverflow上阅读很多帖子，并尝试过这样的代码：

 < ComboBox.Resources> 
< SolidColorBrush x：Key ={x：Static SystemColors.HighlightBrushKey}Color =Red/> 
< /ComboBox.Resources> 
  

，结果如下：

但这不是我想要的。我想更改此背景：

我该如何做？

解决方案

Naive Solution ：
只需向资源中添加刷子并通过ComboBox的Background属性（通过StaticResource绑定）引用它：

 < Window x：Class =WpfApplication2.MainWindow
 xmlns =http://schemas.microsoft.com/winfx/2006/xaml/presentation
 xmlns ：x =http://schemas.microsoft.com/winfx/2006/xaml
 Title =MainWindowHeight =350Width =525> 
< Window.Resources> 
< SolidColorBrush x：Key =BackgroundColorKeyColor =Red/> 
< Style TargetType ={x：Type ComboBox}> 
< Style.Triggers> 
< Trigger Property =IsMouseOverValue =True> 
< Setter Property =BackgroundValue ={StaticResource BackgroundColorKey}/> 
< / Trigger> 
< / Style.Triggers> 
< / Style> 
< /Window.Resources> 
< Grid> 
< ComboBox Height =25/> 
< / Grid> 
  

问题：
背景颜色将重置为默认颜色。解决这个问题的唯一解决方案是覆盖组合框的默认模板。

修复：
修改默认的ComboBox模板。
msdn上存在ComboBox默认模板。以下是链接 - http://msdn.microsoft .com / en-us / library / ms752094（v = vs.100）.aspx 。请参阅ComboBox ControlTemplate示例部分。

I would like to change the background (mouseover) color of my combobox when i move with a mouse over it.

I have read many post on stackoverflow and have tried a code like this:

<ComboBox.Resources>
    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red"/>
</ComboBox.Resources>

and thats the result:

But that's not what I wanted. I want to change this background:

How can I do that?

解决方案

Naive Solution: Just add brush to the resources and reference it from the Background property (via StaticResource binding) of the ComboBox:

<Window x:Class="WpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <SolidColorBrush x:Key="BackgroundColorKey" Color="Red"/>
    <Style TargetType="{x:Type ComboBox}">
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Background" Value="{StaticResource BackgroundColorKey}" />
            </Trigger>
        </Style.Triggers>
    </Style>
</Window.Resources>
<Grid>
    <ComboBox  Height="25"/>
</Grid>

Problem: After item is selected the background color is reset back to the default color. The only solution to fix this is to override the default template of the combobox.

Fix: Modify default ComboBox template. ComboBox default template is present on msdn. Here is the link - http://msdn.microsoft.com/en-us/library/ms752094(v=vs.100).aspx. See "ComboBox ControlTemplate Example" section.
