我试图将Syncfusion TaskBar绑定到ObservableCollection,并有一个TaskBarItem列表。 使用代码隐藏,项目添加如下:
TaskBar taskBar = new TaskBar();
TaskBarItem taskBarItem1 = new TaskBarItem();
taskBarItem1.Header = "TaskBarItem1";
TextBlock textBlock1 = new TextBlock();
textBlock1.Text = "This TaskBar that have a TaskBarItem.";
taskBarItem1.Items.Add(textBlock1);
taskBar.Items.Add(taskBarItem1);
这个XAML:
<syncfusion:TaskBar Grid.Row="1"
VerticalAlignment="Stretch"
ItemsSource="{Binding Path=DataContext.Categories, RelativeSource={RelativeSource AncestorType=localV:MainWindow}}">
<syncfusion:TaskBar.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=FirstName}"/>
</DataTemplate>
</syncfusion:TaskBar.ItemTemplate>
</syncfusion:TaskBar>
给我一个TaskBarItems列表,其中Header显示FirstName,而任何TaskBarItem的可扩展区域都没有。如何在可扩展区域中使用正确的绑定/模板来查看标题和数据?

我希望您能够定义ItemContainerStyle
或ContentTemplate
:
<syncfusion:TaskBar Grid.Row="1"
VerticalAlignment="Stretch"
ItemsSource="{Binding Path=DataContext.Categories, RelativeSource={RelativeSource AncestorType=localV:MainWindow}}">
<syncfusion:TaskBar.ItemContainerStyle>
<Style TargetType="syncfusion:TaskBarItem">
<Setter Property="Header" Value="{Binding Path=FirstName}" />
<Setter Property="Content">
<Setter.Value>
<TextBlock>This TaskBar that have a TaskBarItem</TextBlock>
</Setter.Value>
</Setter>
</Style>
</syncfusion:TaskBar.ItemContainerStyle>
</syncfusion:TaskBar>
