Question

我正在使用MahApps TabControl。如果我从xaml添加项目，我可以设置＆＃34; CloseButtonEnabled = true＆＃34;并显示关闭按钮，当我尝试绑定ItemSource时，不会出现关闭按钮。任何想法，我怎么能解决这个问题？

以下是我的示例代码：

SELECT "VBUK-UVALS",
       CASE ("VBUK-UVALS") WHEN 'A' THEN 'Closed'
                           WHEN 'B' THEN 'Open' -- CASE ("VBUK-UVALS") removed
                           ELSE 'Other'
       END AS "ColumnA"
FROM   "Local"."INFOSET"."ZCA_TESTAR"

Answer 1

您可以尝试以下方法：

<Window.Resources>
<Style x:Key="MyCustomTabItem" BasedOn="{StaticResource MetroTabItem}" TargetType="{x:Type Controls:MetroTabItem}">
    <Setter Property="Controls:ControlsHelper.HeaderFontSize" Value="15"/>
    <Setter Property="Foreground" Value="Red"/>
    <Setter Property="CloseButtonEnabled" Value="True"/>
</Style>
</Window.Resources>
<Controls:MetroTabControl ItemsSource="{Binding AvailableFiles}" ItemContainerStyle="{StaticResource MyCustomTabItem}" SelectedIndex="{Binding SelectedIndex}"  Grid.Row="1" >           
    <Controls:MetroTabControl.ItemTemplate >
        <DataTemplate>
            <TextBlock Text="{Binding Title}" />
        </DataTemplate>
    </Controls:MetroTabControl.ItemTemplate>
</Controls:MetroTabControl>

Answer 2

此处的问题是您覆盖MetroTabItem的完整样式。

如果您只想要进行其他更改，请执行此操作

<Window.Resources>
    <Style BasedOn="{StaticResource {x:Type Controls:MetroTabItem}}" TargetType="{x:Type Controls:MetroTabItem}">
        <Setter Property="Controls:ControlsHelper.HeaderFontSize" Value="15"/>
        <Setter Property="Foreground" Value="Red"/>
        <Setter Property="CloseButtonEnabled" Value="True"/>
    </Style>
</Window.Resources>

MetroTabItem中的BasedOn="{StaticResource MetroTabItem}"是一种风格，而不是类型。

希望有所帮助！

当使用ItemSource = {Binding ..}时，Mahapps TabControl无法设置CloseButtonEnabled = true
