我有一个TabControl,它通过DataBinding获取选项卡和内容。与普通的选项卡不同,我希望所有选项卡的选项卡都是自定义形状(比如椭圆),所以我有一个ControlTemplate,我想应用于所有选项卡。作为WPF的新手,我只是对如何在使用Databinding时将controlTemplate应用于TabControl的tabItem标头感到困惑?
<Window.Resources>
<ControlTemplate x:Key="TabItemControlTemplate1" TargetType="{x:Type TabItem}">
<Grid SnapsToDevicePixels="True">
<Border CornerRadius="12" x:Name="Bd" BorderBrush="Red" BorderThickness="1" Padding="{TemplateBinding Padding}">
<ContentPresenter x:Name="Content" ContentTemplate="{TemplateBinding HeaderTemplate}" Content="{TemplateBinding Header}" ContentStringFormat="{TemplateBinding HeaderStringFormat}" ContentSource="Header" HorizontalAlignment="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type ItemsControl}}}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{Binding VerticalContentAlignment, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type ItemsControl}}}"/>
</Border>
</Grid>
</ControlTemplate>
</Window.Resources>
<Grid x:Name="LayoutRoot">
<TabControl
ItemsSource="{Binding CarCollection}">
<TabControl.ItemTemplate>
<!-- this is the header template-->
<DataTemplate>
<TextBlock
Text="{Binding DisplayName}" />
</DataTemplate>
</TabControl.ItemTemplate>
<TabControl.ContentTemplate>
<!-- this is the body of the TabItem template-->
<DataTemplate>
<ContentControl
Content="{Binding Value}" />
</DataTemplate>
</TabControl.ContentTemplate>
</TabControl>
</Grid>
在那些不使用数据绑定的情况下,我知道如何应用它。问题是当使用数据绑定时,我可以通过下面的代码来实现这一点。
<TabControl HorizontalAlignment="Left" Height="224" Margin="72,66,0,0" VerticalAlignment="Top" Width="412">
<TabItem Header="TabItem" Template="{DynamicResource TabItemControlTemplate1}" Height="19.96" VerticalAlignment="Top">
<Grid Background="#FFE5E5E5"/>
</TabItem>
<TabItem Header="TabItem">
<Grid Background="#FFE5E5E5"/>
</TabItem>
</TabControl>
有什么帮助吗?
您可以尝试使用Style
设置绑定生成的TabItem
的Template
:
<TabControl ItemsSource="{Binding CarCollection}">
<TabControl.Resources>
<Style TargetType="TabItem">
<Setter Property="Template" Value="{DynamicResource TabItemControlTemplate1}"/>
</Style>
</TabControl.Resources>
<TabControl.ItemTemplate>
<!-- this is the header template-->
<DataTemplate>
<TextBlock Text="{Binding DisplayName}" />
</DataTemplate>
</TabControl.ItemTemplate>
<TabControl.ContentTemplate>
<!-- this is the body of the TabItem template-->
<DataTemplate>
<ContentControl Content="{Binding Value}" />
</DataTemplate>
</TabControl.ContentTemplate>
</TabControl>
