Question

我正在开发一个自定义控件，并希望将两个依赖项属性传递给控件样式的setter中的Multi Converter。我的转换器启动，但值显示为UnsetValues。

xmlns:custom="clr-namespace:WPFStyles.CustomControls"
                xmlns:con="clr-namespace:WPFStyles.Converters">

<con:PopUpVisibilty x:Key="PopUpVisibility"/>

<Style TargetType="{x:Type custom:PopUpNotification}">
    <Setter Property="MaxHeight" Value="150"/>
    <Setter Property="MaxWidth" Value="250"/>
    <Setter Property="Visibility">
        <Setter.Value>
            <MultiBinding Converter="{StaticResource PopUpVisibility}">
                <Binding RelativeSource="{RelativeSource Mode=FindAncestor,AncestorType={x:Type custom:PopUpNotification}}" Path="IsOpen"/>
                <Binding RelativeSource="{RelativeSource Mode=FindAncestor,AncestorType={x:Type custom:PopUpNotification}}" Path="Header"/>
            </MultiBinding>
        </Setter.Value>
    </Setter>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type custom:PopUpNotification}">

如何正确传递这些属性的任何帮助都会很棒。

我希望这可行：

<MultiBinding Converter="{StaticResource PopUpVisibility}">
    <Binding RelativeSource="{RelativeSource Self}" Path="IsOpen"/>
    <Binding RelativeSource="{RelativeSource Self}" Path="Header"/>
</MultiBinding>

如何将RelativeSource Self绑定到MultiConverter WPF
