> IsEnabled 属性 ComboBoxItem
到 false
You can achieve this by setting IsEnabled
property of a ComboBoxItem
to false
;
因此ComboBox的 ItemSource
(即 Cars
在你的case)可以是一个对象有一些属性(例如 IsSelectable
)指定它是应该启用或禁用,然后使用它与样式,使项目不可选择。
So each item in ComboBox's ItemSource
(i.e. Cars
in your case) can be an object having some property (say IsSelectable
) specifying whether it should be enabled or disabled and then use it with a style to make an item un-selectable. something like this -
<Style TargetType="ComboBoxItem">
<Setter Property="IsEnabled" Value="{Binding IsSelectable}"/>
</Style>
更新:
<Grid>
<ComboBox
Width="120"
Margin="87.2,44.8,0,0"
HorizontalAlignment="Left"
VerticalAlignment="Top"
ItemTemplateSelector="{StaticResource QualityComboBoxTemplateSelector}"
ItemsPanel="{DynamicResource ItemsPanelTemplateHorizontal}"
ItemsSource="{Binding Cars}"
SelectedItem="{Binding SelectedItm}">
<ComboBox.ItemContainerStyle>
<Style TargetType="ComboBoxItem">
<Setter
Property="IsEnabled"
Value="{Binding IsSelectable}" />
</Style>
</ComboBox.ItemContainerStyle>
</ComboBox>
</Grid>
