Question

我有一个ListBox，当一个事件发生在ListBox之外时（点击一个按钮）我需要申请

CategoriesUnselectedDataTemplate

到CategoriesListBox

的元素

Anyidea如何解决这个问题？

        <Custom:SurfaceListBox
                x:Name="CategoriesListBox"
                ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                ScrollViewer.VerticalScrollBarVisibility="Hidden"
                ManipulationDelta="CategoriesListBox_ManipulationDelta"
                IsManipulationEnabled="True"
                SelectionChanged="CategoriesListBox_SelectionChanged"
                ItemTemplate="{DynamicResource CategoriesUnselectedDataTemplate}"
                VerticalContentAlignment="Stretch"
                HorizontalContentAlignment="Stretch"
                SelectionMode="Single"
                Margin="115,131,-117,-49">
        </Custom:SurfaceListBox>



    <DataTemplate x:Key="CategoriesUnselectedDataTemplate">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <TextBlock Name="titleCategory" TextWrapping="Wrap"
                           Text="{Binding CapitalizedDescription, FallbackValue=CategoryName}"
                           Foreground="#2fb8dc"
                           FontFamily="/GateeClientWPF;component/Fonts/#Letter Gothic L"
                           HorizontalAlignment="Left"
                           VerticalAlignment="Center"
                           FontSize="30"
                           Margin="0,10"/>
            <Image Source="Assets/common/right_grey.png" Width="20" Height="20" Visibility="Visible" HorizontalAlignment="Left" VerticalAlignment="Center" d:LayoutOverrides="Height" Grid.Column="1" Margin="10,0,0,0"/>
        </Grid>
    </DataTemplate>

如何将数据模板应用于ListBox？
