我是wpf的新手,我无法弄清楚如何在选择标签项时设置图像。
我写了一个风格,但它不起作用。它向我展示了任何东西......
<Style TargetType="TabItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Grid>
<StackPanel Orientation="Horizontal">
<HeaderedItemsControl Name="img" >
</HeaderedItemsControl>
</StackPanel>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Visibility" TargetName="img" Value="Visible"/>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter Property="Visibility" TargetName="img" Value="Hidden"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
对于选项卡控件,我编写了代码:
<TabControl Name="tabControl1"
HorizontalAlignment="Left"
VerticalAlignment="Top"
Height="311"
Width="503">
<TabItem Name="tabItem1" Background="Red" >
<TabItem.Header>
<Grid>
<TextBlock Text=" First" Width="100" Margin="-2,33,4,16" />
<Image Name="img" Source="menu.png" Height="20" Margin="0,60,0,0" />
</Grid>
</TabItem.Header>
<Grid>
<TextBox Name="denumire" Margin="31,20,169,67" Height="20" Width="60"/>
</Grid>
</TabItem>
<TabItem Name="tabItem2" Header="tabItem2" Background="Red">
</TabItem>
</TabControl>
答案 0 :(得分:0)
按照您的风格,将HeaderedItemsControl
更改为以下内容:
<HeaderedItemsControl>
<TextBlock Text="{TemplateBinding Header}" Width="100"/>
<Image x:Name="img" Source="menu.png" Height="20" />
</HeaderedItemsControl>
并删除<TabItem.Header>
中的整个TabControl
部分。
