我是WPF的新手,我无法让DataTemplateKey找到我的ListBox。
<Window.Resources>
<ControlTemplate x:Key="FocusTemplate" >
<Rectangle Fill="Azure" Width="290" Height="55" />
</ControlTemplate>
<Style x:Key="FocusStyle" TargetType="{x:Type Control}">
<Setter Property="Template" Value="{StaticResource FocusTemplate}"/>
</Style>
<Style TargetType="ListBoxItem">
<EventSetter Event="GotFocus" Handler="ListItem_GotFocus"></EventSetter>
</Style>
<DataTemplate DataType="{x:Type TextBlock}">
</DataTemplate>
<DataTemplate x:Key="CustomListData" DataType="{x:Type ListBox}">
<Border BorderBrush="Black" BorderThickness="1" Margin="-2,0,0,-1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="55*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleX="1" ScaleY="1"/>
<SkewTransform AngleX="0" AngleY="0"/>
<RotateTransform Angle="0"/>
<TranslateTransform X="0" Y="0"/>
</TransformGroup>
</Grid.RenderTransform>
<!--<ScrollViewer x:Name="PART_ContentHost" />-->
<TextBox Width="290" TextAlignment="Left" VerticalContentAlignment="Center" BorderThickness="0" BorderBrush="Transparent"
Foreground="#FF6FB8FD"
FontSize="18"
FocusVisualStyle="{StaticResource FocusStyle}"
Name="editingBox"
TextWrapping="Wrap"
Text="{Binding .}"
Grid.Column="1"
Grid.Row="1"
MinHeight="55"
Cursor="Hand"
IsReadOnly="True"
>
<TextBox.Background>
<LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
<LinearGradientBrush.RelativeTransform>
<TransformGroup>
<ScaleTransform CenterX="0.5" CenterY="0.5"/>
<SkewTransform CenterX="0.5" CenterY="0.5"/>
<RotateTransform Angle="0" CenterX="0.5" CenterY="0.5"/>
<TranslateTransform/>
</TransformGroup>
</LinearGradientBrush.RelativeTransform>
<GradientStop Color="#FF2D4984"/>
<GradientStop Color="#FF182D56" Offset="0.042"/>
</LinearGradientBrush>
</TextBox.Background>
</TextBox>
</Grid>
</Border>
</DataTemplate>
<Style TargetType="{x:Type ListBox}">
<Setter Property="ItemTemplate" Value="{StaticResource CustomListData }" />
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" />
</Style>
</Window.Resources>
<Window.DataContext>
<ObjectDataProvider
ObjectType="{x:Type local:ImageLoader}"
MethodName="LoadImages"
/>
</Window.DataContext>
<ListBox ItemsSource="{Binding}" Width="320" Background="#FF021422" BorderBrush="#FF1C4B79">
<ListBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}">Transparent</SolidColorBrush>
</ListBox.Resources>
</ListBox>
以下代码将找到TextBlock
var key = new System.Windows.DataTemplateKey(typeof(TextBlock));
var r = (DataTemplate)this.FindResource(key);
但是,当我将类型更改为ListBox时,无法找到该键。我错过了什么?

您已为ListBox DataTemplate
提供了另一个密钥,具体为x:Key="CustomListData"
。
x:Key
属性优先于基于DataTemplateKey
生成的自动DataType
。删除该密钥,即可找到自动DataTemplateKey
。
