Try this Instead,
试试这个，
<TabControl x:Name="tabCtrlMain" ItemsSource="{Binding Items}" >
<TabControl.Resources>
<Style TargetType="TabItem">
<Setter Property="Header" Value="{Binding FileName}" />
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate DataType="{x:Type TabItem}">
<Border x:Name="grid">
<ContentPresenter>
<ContentPresenter.Content>
<TextBlock Text="{TemplateBinding Content}"/>
</ContentPresenter.Content>
</ContentPresenter>
</Border>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
</TabControl>

I know this is awfully old now, but I thought I'd throw my two cents in just for the sake of completeness and historical accuracy :)
我知道这现在已经很老了，但我想我会为了完整性和历史准确性而投入我的两分钱:)
I prefer to use the ItemContainerStyle to do the same thing just because it feels a little cleaner to me because it states the purpose exactly:
我更喜欢使用 ItemContainerStyle 来做同样的事情，因为它对我来说感觉更简洁，因为它准确地说明了目的：
<TabControl ItemsSource="{Binding Items}">
<TabControl.ItemContainerStyle>
<Style TargetType="TabItem">
<Setter Property="Header" Value="{Binding FileName}" />
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<Border>
<TextBlock Text="{Binding Content}" />
</Border>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.ItemContainerStyle>
</TabControl>
Also, if the only goal is to get the FileName into the tabs then it can be much simpler:
此外，如果唯一的目标是将 FileName 放入选项卡中，那么它可以简单得多：
<TabControl ItemsSource="{Binding Items}" DisplayMemberPath="FileName" />
