这是我的组合框数据模板
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel KeyboardNavigation.DirectionalNavigation="Contained" Orientation="Horizontal">
<Image Source="{Binding Path=Flag}" Height="25"></Image>
<TextBlock Margin="10,0,0,0" Text="{Binding Path=Name}" VerticalAlignment="Center"></TextBlock>
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
<ComboBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel/>
</ItemsPanelTemplate>
</ComboBox.ItemsPanel>
它工作正常,我想在鼠标位于行区域中的任何位置时选择行,而不仅仅是当它刚刚超过数据时。
谢谢
好的,它由@Jehof 解决,谢谢。第二个问题是“如果我设置模板,为什么它不起作用?” 像这样
<Style TargetType="ComboBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="SnapsToDevicePixels" Value="true"/>
<!--<Setter Property="OverridesDefaultStyle" Value="true"/>-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ComboBoxItem">
<Border Name="Border" Padding="2" SnapsToDevicePixels="False" BorderThickness="1">
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsHighlighted" Value="true">
<Setter TargetName="Border" Property="Background" Value="{StaticResource BackgroundHighlighted}"/>
<Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource BorderBrushHighlighted}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
如果删除 <Setter Property="Template">
... 部分它的工作原理!
