WPF Telerik TreeListView样式设计

Telerik控件 TreeListView

修改其中样式

1、添加TreeListView控件

<telerik:RadTreeView x:Name="ObjecTreeView" Padding="0,5,0.5,5" Grid.Row="1" BorderThickness="0" ScrollViewer.HorizontalScrollBarVisibility="Disabled"
telerik:StyleManager.Theme="Windows8" SelectionMode="Single" Background="White" SelectionChanged="ObjecTreeView_OnSelectionChanged"
SelectedValuePath="DisplayName" AutoScrollToSelectedItem="True" IsExpandOnSingleClickEnabled="True" FocusVisualStyle="{x:Null}" >
            <telerik:RadTreeView.ItemTemplateSelector>
                <styleSelector:ObjectTreeTemplateSelector ItemTemplate="{StaticResource ObjectItemTemplate}" 
TreeItemTemplate="{StaticResource ObjectTreeTemplate}"></styleSelector:ObjectTreeTemplateSelector>
            </telerik:RadTreeView.ItemTemplateSelector>
        </telerik:RadTreeView>

View Code

通过模板选择器，选择相应的模板

2、模板

1）级联模板

<!--对象树母模板-->
    <HierarchicalDataTemplate x:Key="ObjectTreeTemplate"
ItemsSource="{Binding ObjectTypeModels}"
ItemTemplate="{StaticResource ObjectItemTemplate}" ItemContainerStyle="{StaticResource RadTreeViewItemStyle1}">
        <StackPanel Orientation="Horizontal">
            <Image Source="..\..\Images\操作图标\内容\文件夹.png" VerticalAlignment="Center" Height="14" Margin="0,0,5,0"/>
            <CheckBox x:Name="MotherCheckBox" Visibility="{Binding CheckBoxVisibility,Mode=TwoWay}"
IsChecked="{Binding IsChecked,Mode=TwoWay}" Click="ButtonBase_OnClick"></CheckBox>
            <TextBlock Text="{Binding DisplayName,Mode=TwoWay}" Margin="5,0,0,0" />
        </StackPanel>
    </HierarchicalDataTemplate>

View Code

2）子模板

<!--对象树子模板-->
    <DataTemplate x:Key="ObjectItemTemplate">
        <ContentControl Content="{Binding}">
            <ContentControl.Style>
                <Style TargetType="ContentControl">
                    <Setter Property="ContentTemplate" Value="{StaticResource ObjectItemTemplateNoSelect}"></Setter>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadTreeViewItem}}, Path=IsSelected}" Value="true">
                            <Setter Property="ContentTemplate" Value="{StaticResource ObjectItemTemplateSelected}"></Setter>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </ContentControl.Style>
        </ContentControl>
    </DataTemplate>

View Code

选中样式

<!--对象树选中状态子模板-->
    <DataTemplate x:Key="ObjectItemTemplateSelected">
        <StackPanel Orientation="Horizontal">
            <Image Source="..\..\Images\操作图标\内容\文件_Click.png" VerticalAlignment="Center" Height="14" Margin="0,0,5,0"/>
            <CheckBox x:Name="ChildCheckBox" Visibility="{Binding CheckBoxVisibility,Mode=TwoWay}" IsChecked="{Binding IsChecked,Mode=TwoWay}"></CheckBox>
            <TextBlock Text="{Binding DisplayName,Mode=TwoWay}" Foreground="#FFB83838" FontWeight="Black" Margin="5,0,0,0"/>
        </StackPanel>
    </DataTemplate>

View Code

未选中样式

<!--对象树未选中状态子模板-->
    <DataTemplate x:Key="ObjectItemTemplateNoSelect">
        <StackPanel Orientation="Horizontal">
            <Image Source="..\..\Images\操作图标\内容\文件.png" VerticalAlignment="Center" Height="14" Margin="0,0,5,0"/>
            <CheckBox x:Name="ChildCheckBox" Visibility="{Binding CheckBoxVisibility,Mode=TwoWay}" IsChecked="{Binding IsChecked,Mode=TwoWay}"></CheckBox>
            <TextBlock Text="{Binding DisplayName,Mode=TwoWay}" Margin="5,0,0,0" />
        </StackPanel>
    </DataTemplate>

View Code

2、TreeListView的样式，设置子项的容器、焦点样式等。

<!--模板的样式-->
    <Style x:Key="RadTreeViewItemStyle1" TargetType="{x:Type telerik:RadTreeViewItem}">
        <Setter Property="FocusVisualStyle">
            <Setter.Value>
                <Style>
                    <Setter Property="Control.Template">
                        <Setter.Value>
                            <ControlTemplate>
                                <Rectangle Margin="0" Stroke="Transparent" StrokeThickness="0"/>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </Setter.Value>
        </Setter>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>

                <ControlTemplate TargetType="{x:Type telerik:RadTreeViewItem}">
                    <Grid x:Name="RootElement">
                        <Grid.RowDefinitions>
