我想在TabControl的标题中显示Image
这个问题(WPF TabItem - Image Binding)似乎是正确的,但我使用了触发器,但它对我的代码没有帮助。
以下是我提供的内容:
<TabControl Name="MainTabControl" Margin="0,28,0,0" TabStripPlacement="Top" >
<TabControl.Resources>
<Image x:Key="imgProfile" Source="/Icons/red icons/profile.png" />
<Image x:Key="imgComment" Source="Icons/red icons/notification.png" />
<Style TargetType="TabItem" >
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<WrapPanel>
<TextBlock Text="{Binding}"
MouseDown="UIElement_OnMouseDown"
FontSize="18"
/>
<Image Height="25" Margin="4,0,4,0"
Source="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Tag.Source}" />
</WrapPanel>
</DataTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" BorderThickness="1,1,1,0" BorderBrush="Gainsboro" CornerRadius="0" Margin="2,0">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
Margin="5,2"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="BorderBrush" Value="Transparent" />
<Setter TargetName="Border" Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="{DynamicResource TabItemNormal}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
<TabItem Name="tiProfile" Header="a" Tag="{StaticResource imgProfile}"></TabItem>
<TabItem Name="tiComment" Header="b" Tag="{StaticResource imgComment}"></TabItem>
</TabControl>
答案 0 :(得分:1)
从TabItem.HeaderTemplate到TabItem.Tag的绑定必须通过TabItem类型的FindAncestor。
在Resources中创建Images,创建BitmapImage,并将它绑定到Image.Source。
所以,资源:
Toys A B C D E F
---- ----- ------- ---- --- ---- ---
A 10.55,12.60
B 7.60,8.90
C 8.90,10.50
D 11.50,13.40
E 17.50,20.30
F 2.57,3.50
Header DataTemplate:
<BitmapImage x:Key="imgProfile" Source="/Icons/red icons/profile.png" />
<BitmapImage x:Key="imgComment" Source="Icons/red icons/notification.png" />
