wpf combobox的三角形的颜色怎么写

Posted 2023-04-12

原有的 是黑色的，我想改成自己想要的 颜色？？怎么改？还有就是下拉 后选项的颜色怎么写的？？

参考技术A 正好刚写的Combobox的模板，拿着玩吧。。。觉得不满意就重写，没必要纠结于他怎么做。。。默认模板都不够爽。。。只要修改模板中相关控件的颜色即可。。。
<ControlTemplate TargetType="TextBox" x:Key="ComboBox_TextBox">
<Border x:Name="PART_ContentHost" Focusable="False" Background="TemplateBinding Background" BorderBrush="White" BorderThickness="1"/>
</ControlTemplate>
<ControlTemplate x:Key="ComboBoxToggleButton" TargetType="x:Type ToggleButton">
<Border Grid.Column="1" Cursor="Hand" BorderBrush="White" BorderThickness="1" Background="#ff00a0a0" Height="21" Width="21">
<Path Data="M 6,7 L 10.5,14 L 15,7 z" Fill="White"/>
</Border>
</ControlTemplate>
<Style TargetType="ComboBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ComboBox" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Border Grid.ColumnSpan="2" BorderBrush="White" BorderThickness="1"/>

<ToggleButton Grid.Column="1" Template="DynamicResource ComboBoxToggleButton" x:Name="ToggleButton" Focusable="false" IsChecked="Binding Path=IsDropDownOpen, Mode=TwoWay, RelativeSource=RelativeSource TemplatedParent" ClickMode="Press"/>

<TextBox Visibility="Hidden" Template="DynamicResource ComboBox_TextBox" HorizontalAlignment="Left" x:Name="PART_EditableTextBox" Style="x:Null" VerticalAlignment="Center" Focusable="True" Background="Transparent" IsReadOnly="TemplateBinding IsReadOnly"/>

wpf里combobox怎么取数据

怎么把combobox中的显示的值写入数据库里，我用
string s = null;
s = comboBox1.SelectedValue.ToString();
取combobox1的值发现取到得是“system.windows.control.comboboxItem:基层”
而我想要的就是其中显示的“基层"
急求！^_^

参考技术A 你好：

combox是这样组成的：combox的Items属性包含多个comboxItem，comboxItem是保存数据的地方。
通过comboBox1.SelectedItem.Content或omboBox1.Items[index].Content来获得的 参考技术B

有没有使用绑定？

有没有指定SelectedValuePath？

追问

没有，请问怎么用？

追答

如果你是直接在Xaml里面添加的Item，那试试直接用s = comboBox1.Text;

追问

基层
高级

追答

直接用s = comboBox1.Text
