Question

我正在尝试使用时间轴设计ItemsControl，该时间轴显示与箭头/线条相关的子项目。这些项目是自定义控件，我想将这些行连接到控件的边框。

最好的方法是什么？

Answer 1

好的，这是Itemscontrol的代码：

 <ItemsControl DataContext="{StaticResource StratCol1}" ItemsSource="{Binding}">
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Horizontal" />
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>

        </ItemsControl>

这是项目集合：

<ctrl:StrategyCollection x:Key="StratCol1" >
        <ctrl:StrategyNode Height="150" Width="Auto" Title="Title A" StrategyParameter="{StaticResource dpara}" Period="All year" IsChecked="False"/>
        <ctrl:StrategyNode Height="150" Width="Auto" Title="Title B" StrategyParameter="{StaticResource dpara}" Period="3 Months" IsChecked="False" />
    </ctrl:StrategyCollection>

这是项目的风格：

<Style TargetType="{x:Type ctrl:StrategyNode}">
        <Setter Property="SnapsToDevicePixels"
      Value="true" />
        <Setter Property="OverridesDefaultStyle"
      Value="true" />


        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ctrl:StrategyNode}">
                    <ControlTemplate.Resources>

                    </ControlTemplate.Resources>

                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto" />
                            <ColumnDefinition Width="Auto" />
                        </Grid.ColumnDefinitions>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal" />
                                <VisualState x:Name="MouseOver">

                                    </Storyboard>
