在WPF中数据绑定TabControl时,如何使用自定义TabItem控件？

Question

我有一个派生自定义控件TabItem,我想将该自定义数据绑定TabItem到一个股票TabControl.我宁愿避免TabControl为这种罕见的情况创建一个新的.

这就是我所拥有的,并且我没有运气得到正确的控件来加载.在这种情况下,我想使用我的ClosableTabItem控件而不是库存TabItem控件.

<TabControl x:Name="tabCases" IsSynchronizedWithCurrentItem="True" 
            Controls:ClosableTabItem.TabClose="TabClosed" >
    <TabControl.ItemTemplate>
        <DataTemplate DataType="{x:Type Controls:ClosableTabItem}" >
            <TextBlock Text="{Binding Path=Id}" />
        </DataTemplate>
    </TabControl.ItemTemplate>
    <TabControl.ContentTemplate>
        <DataTemplate DataType="{x:Type Entities:Case}">
            <CallLog:CaseReadOnlyDisplay DataContext="{Binding}" />
        </DataTemplate>
    </TabControl.ContentTemplate>
</TabControl>

编辑:这是我最终得到的,而不是尝试绑定自定义控件.我从前一个问题得到的" CloseCommand " .

    <Style TargetType="{x:Type TabItem}" BasedOn="{StaticResource {x:Type TabItem}}" >
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TabItem}">
                    <Border 
                            Name="Border"
                            Background="LightGray"
                            BorderBrush="Black" 
                            BorderThickness="1" 
                            CornerRadius="25,0,0,0"
                            SnapsToDevicePixels="True">
                        <StackPanel Orientation="Horizontal">
                        <ContentPresenter x:Name="ContentSite"
                              VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header"
                              Margin="20,1,5,1"/>
                            <Button 
                                Command="{Binding Path=CloseCommand}"
                                Cursor="Hand"
                                DockPanel.Dock="Right"
                                Focusable="False"
                                Margin="1,1,5,1"
                                Background="Transparent"
                                BorderThickness="0">
                                <Image Source="/Russound.Windows;component/Resources/Delete.png" Height="10" />
                            </Button>
                        </StackPanel>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsSelected" Value="True">
                            <Setter Property="FontWeight" Value="Bold" />
                            <Setter TargetName="Border" Property="Background" Value="LightBlue" />                            
                            <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
                            <Setter TargetName="Border" Property="BorderBrush" Value="DarkBlue" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Answer 1

找到一种方法,从TabControl派生一个类并覆盖这个函数,在我的情况下我希望tab控件的项目(绑定时)是CloseableTabItems

public class CloseableTabControl : TabControl
    {
        protected override DependencyObject GetContainerForItemOverride()
        {
            return new CloseableTabItem();
        }
    }
