绑定头像模板的Silverlight

我有一个手风琴控件，这是xaml：

<UserControl x:Class="CasesPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit"    
mc:Ignorable="d"
d:DesignHeight="1050" d:DesignWidth="1600">
<UserControl.Resources>
    <DataTemplate x:Key="AccordionItemHeaderTemplate">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>
            <TextBlock Text="{Binding CaseName}"/>
        </Grid>
    </DataTemplate>
</UserControl.Resources>
<Border Margin="20,20,0,20" Background="White" BorderBrush="Transparent" BorderThickness="0" CornerRadius="10">
<toolkit:Accordion Margin="30"  Name="CasesListAccordion" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" ItemContainerStyle="{StaticResource AccordionContainerStyleLawBot}" BorderBrush="{x:Null}" SelectionMode="ZeroOrOne" SelectionSequence="CollapseBeforeExpand" Style="{StaticResource NewAccordionStyle}"
                   ItemsSource="{Binding}" AccordionButtonStyle="{StaticResource AccordionButtonStyleNotEdited}"  HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" Foreground="Black" Background ="White"
         SelectedItemsChanged="CasesListAccordion_SelectedItemsChanged">
    </toolkit:Accordion>
</Border>

类ECase有一个名为CaseName的成员。 我将datatemplate中xaml中的此成员绑定到textblock：

<DataTemplate x:Key="AccordionItemHeaderTemplate">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>
            <TextBlock Text="{Binding CaseName}"/>
        </Grid>
    </DataTemplate>

而且案例名称仍然不会显示在手风琴项目的标题中

有什么想法吗？

您应该将对象指定给Header属性

试一试

<DataTemplate x:Key="AccordionItemHeaderTemplate">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>
            <TextBlock Text="{Binding CaseName}"/>
        </Grid>
    </DataTemplate>

item.DataContext = Case;

item.Header = Case;
