<Image Source="{Binding Photo}" Width="50" Height="50"
Grid.Column="0" Grid.RowSpan="1"/>
<TextBlock Text="{Binding Name}" Grid.Column="1"
Grid.ColumnSpan="1" HorizontalAlignment="Center" VerticalAlignment="Center"/>

</DataTemplate>
</Window.Resources>

其二
<DataTemplate x:Key="hightlightTmp">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
